upgrade Solutions Enabler - getting symcfg discover error message

if you get this message after upgrading solutions enabler and trying to refresh the database via symcfg discover, then do the following:

# /usr/symcli/bin/symcfg discover
The SYMAPI database file cannot be used because it was written by a version of SYMAPI that is no longer supported

then do this:
#  > /var/symapi/db/symapi_db.bin

That's the same as doing: cat /dev/null > /var/symapi/db/symapi_db.bin

Now you can do the symcfg discover without errors.

long hostname - kernel tuneable.

Long hostname - longer than 8 characters:

If a server is not properly configured for long host names, the kernel tunable  expanded_node_host_names  needs to be set to1 and the server may need to be rebooted (even though the kernel tunable parameter is dynamic).

I believe this only works if you have certain patches installed or at 11.31 or something, not sure.

individual umask in sftp/scp

For HPUX (at least some of the 11.31 versions) the following can be used in sshd_config to set the umask for individual users or groups:

Add the following two lines at the end of the file to configure the sftp umask for a group of users.

Match Group  <group name>
ForceCommand  internal-sftp  -u 73

Or, add the following two lines at the end of the file to configure the sftp umask for a single user.

Match User   <user name>
ForceCommand  internal-sftp -u 73

syslogd cores

 HP-UX syslog crashes with a core file in /var/adm/syslog.   file /var/adm/syslog/core:  ELF-32 core file - IA64 from 'syslogd' - received SIGXFSZ

 

if none of your files in /var/adm/syslog are over 2GB, then change the LOG_SIZE to NOLIMIT in /etc/default/syslogd  like this:

 

query value:

ch_rc -l -p LOG_SIZE /etc/default/syslogd

 

set to NOLIMIT:

ch_rc -a -p LOG_SIZE=NOLOMIT /etc/default/syslogd

 

what happened is that OVO (HPOM) process opcle had syslog.log open and it hit 2GB so when syslog was recycled, the opcle process didn't release and the system still thinks that syslog.log is over 2GB.  That's the theory anyway.  I guess if that's the case you probably could just restart OVO/HPOM and that might fix it.

EMC Open Migrator

move / sync data transparently to end user - better than rsync cause
it's synced real time via dynamic kernel module. it works on raw
logical volumes. Here's how it works. you configure new logical
volumes of the exact same size as the old ones using new LUNs (and a
new VG of course, which is a good time to maybe change the VG details
- max PE, etc). then create session files which "pair" up the old LV
to new LV. Once the sync is complete and you can take an outage,
unmount the old LV and VG and new ones too. Then stop the session and
mount the new stuff.

Open Migrator (OpenMigrator or OM) details:

create session file, /tmp/session1_pairs contents:

ECC agent install issues on HPUX

if you have file systems listed in fstab that won't mount, dont think you can get away by doing an -x mount_all_filesystems=false.  You'll probably need to comment them out of fstab.  ECC is sometimes bundled and kicks off a secondary swinstall that doesn't get any options passed to it.

 

also if you get the following message in swagent.log:

An unsupported version of Master Agent was found.  Please uninstall from /usr/ecc to continue.
./install_native.sh[372]: /usr/ecc/install_native.log: Cannot create the specified file.

 

but yet, there is no /usr/ecc.....    it's finding a file in /var/emc/.eccrc and thinks there's a previous version installed - just delete that file and try again.

hpux 11.23 panic lo_realvfs

Panic string: lo_realvfs

 

if you have automountd or autofs turned on and an application or someone tries to access the local machine via /net/HOSTNAME, autofs creates a LOFS mount it since it's a local file sytem.  This rarely cuases problems but there is a known issue with the LOFS code that causes a panic, with Panic string: lo_realvfs in the /etc/shutdownlog

 

The work-around is to add the -L option to AUTOMOUNTD_OPTIONS in the nfsconf file:

check the options first:

ch_rc -vlp AUTOMOUNTD_OPTIONS

 

add the -L option:

ch_rc -ap AUTOMOUNTD_OPTIONS=-L

 

reboot the box or restart NFS:   (you may only have to restart nfs.client, but I have not tested that)

/sbin/init.d/nfs.client stop

/sbin/init.d/nfs.server stop

/sbin/init.d/nfs.core stop

HP SmartArray controller disk replacement steps on HP i2 blades

This is for the BL860c i2 blades (and other i2 models):

Replace a failed LVM mirror disk that is attached to a SmartArray SAS controller.

 

Notes:  For this example /dev/disk/disk2 is the failed disk and /dev/disk/disk4 is the new device that was created because the SAS controller identified a new disk.

Notes:  For this example the SAS controller device is /dev/ciss0

Notes:  The failed disk is in volume group vg00

 

Identify the disk by serial number.  Give the Bay number to the HP CE so they know which disk to replace:

sautil /dev/ciss0 -s

scsimgr get_info -D /dev/rdisk/disk2

 

Deactivate the PV:

pvchange -a n /dev/disk/disk2

 

Replace the failed disk.

 

Activate the WWID of the new disk.  The Error can be ignored.  A new disk device should be created:

scsimgr -f replace_wwid -D /dev/rdisk/disk2 dsf

scsimgr: ERROR: Cannot convert hardware path to an IO tree node

 

Find the new disk device that was created:

ioscan -fNnC disk

 

Create a description file to create the EFI partitions:

# cat >> /tmp/idf << EOF

3

EFI 500MB

HPUX 100%

HPSP 400MB

 

Use idisk to setup the disk partitioning on the new disk device:

idisk -wf /tmp/idf  /dev/rdisk/disk4

insf -e –C disk

 

Assign the old instance number to the replacement disk:

io_redirect_dsf -d /dev/disk/disk2 -n /dev/disk/disk4

 

Verify that /dev/disk/disk2 is in a claimed state:

ioscan –fnNC disk

 

Use mkboot to format and populate the newly created EFI partition:

mkboot -e -l /dev/disk/disk2

 

Change the AUTO file contents to the proper mode:

mkboot -a "boot vmunix -lq" /dev/rdisk/disk2

 

Restore the LVM reserved areas (PVRA/VGRA):

vgcfgrestore –n vg00 /dev/rdisk/disk2_p2

 

Reattach the new disk:

pvchange -a y /dev/disk/disk2_p2

 

Sync volume group:

vgsync vg00

 

Use lvlnboot to ensure that the LVM logical volumes are prepared:

lvlnboot -R

lvlnboot -v

SAS controller on HPUX itanium disk replace

The SAS controller in the first generation BL860C (and other models) has some special commands in order to replace a failed disk.  I would recommend using the built-in RAID-1 capabilities of this controller - that way you no longer need to worry about LVM mirroring.  But if you need to use LVM mirroring then, add the couple steps below to your standard LVM mirror root/boot disk procedure:

#get the SAS controller dsf:

saslist get_info ctrl sasd

#get info on the disks:

sasmgr get_info -D /dev/sasd0 -q raid

#if the disk is working enough to turn on the attention LED:

sasmgr set_attr -D /dev/sasd0 -q lun=/dev/dsk/c0t1d0 -q locate_led=on

AFTER the disk is replaced:

#since each disk will have a unique WWID, the server will assign a new HW path and persistent dsf

#to change them first change the hardware path (legacy style)

sasmgr replace_tgt -D /dev/sasd0 -q old_tgt_hwpath=0/2/1/0.0.0.1.0 -q new_tgt_hwpath=0/2/1/0.0.0.2.0

#then change the persistent dsf

io_redirect_dsf -d /dev/disk/disk3 -n /dev/disk/disk8

sas commands (Hardware mirroring) hp-ux

HPUX SAS controller commands - hardware mirroring (only on some controllers)

status of serial attached SCSI raid set:

sasmgr get_info -D /dev/sasd0 -q raid

get controller HW path and device file

saslist get_info ctrl sasd

get list of LUNs being controlled by the sasd driver

saslist get_info lun sasd

status all physical drives

sasmgr get_info -D /dev/sasd0 -q phy=all

statistics of HBA (for problems)

sasmgr get_stat -D /dev/sasd0

track down disk problems

sasmgr get_stat -D /dev/sasd0 -q phy=all

clear statistics on PHY 1

sasmgr clear_stat -D /dev/sasd0 -q phy_in_port=1

start a search when opening a file in vi

cimprovagt using too much memory

if cimprovagt is using too much memory, you can restart it by restarting the whole cimserver ( /sbin/init.d/cim_server stop / start  OR cimserver -s ; cimserver ).  Or you can just disable then re-enable the module.  There seems to be lots of memory leaks in the modules, or upgrade if possible.

- Identify the provider:

# ps -ef | grep cimprovagt

# cimprovider -l -s

- Disable provider sample:

#cimprovider -d -m MODULE

#cimprovider -l -s

or shutdown/start the module:

#cimprovider -d -m MODULE

#cimprovider -e -m MODULE

excessive dots during HPUX startup

two ways to mitigate a bunch of dots during the startup script process on HP-UX:
Change the GSP/MP/iLO "asynchronous" port to the correct terminal
type: vt100 verses HPTERM. usually you can get in and do a "CA"
(configure asynchronous) and change the console terminal type there.

OR:
One suggestion I've seen on the HP forums is to try setting
"LIST_MODE=1" in /etc/rc.config.d/list_mode, rather than the default
value of zero. This forces the startup to use the same line-oriented
mode regardless of the terminal type. It might be worth a try.

HPUX LVM logical volume size limit

2TB is the max size for a logical volme and file system on 11.23,

AT&T vs T-mobile sim card in straight talk phone

difference between att and tmobile sim card in a straghttalk phone or service:

look at the SIM card numbers. If it starts with 890126 its T-mobile. 890141 for AT&T.
OR  check bottom of packaging of the phone. Look for the white label. Look on the right for an "A" or "T" (AT&T or T-mobile)

Packet tracing in HPUX

quick primer to packet tracing/logging/sniffing in hpux.  "nettl" network tracing and logging, no need for tcpdump (even though it's probably better).

get status on trace or logging:

/usr/sbin/nettl -status [log |trace |all]

start/stop trace:

nettl -tn pduin pduout loopback -e all -tracemax 65536 -f /tmp/me

nettl -tf -e all

the output file can be opened in wireshark/ethereal.

format commands

netfmt -vf nettl.LOG000 > /tmp/nettl.txt

netfmt -nl1f me.TRC000 > me.out

combine both nettl and netfmt to filter results:

add a filter to ~/.netfmtrc like the following for dns

filter tcp_sport 53

filter tcp_dport 53

filter udp_sport 53

filter udp_dport 53

then start the trace (be sure to turn off):

nettl -tn pduin pduout -e ns_ls_ip | netfmt -1

or

nettl -tn pduin pduout -e ns_ls_ip -m 250 -ks 10M -us 30M -nk 5 -nu 5 | netfmt -1

turn it off again, even if control-c (intr) was used:

not a tech topic - the real reason why they hate us

Be honest with yourself, they (the terrorists) don't hate and want to kill us because we're free and our culture is different from their's.  If that was true, then why haven't we been attacked earlier than the 1990's; why isn't Canada, Switzerland, and the Netherlands being attacked?

The real reason, which might be hard for some to accept, is that we have military bases, occupy their "holy land", and invade their country.  Violence is not acceptable, but put yourself in their shoes and ask what you would do if that was happening in your country.

no powerpath and getting LUN ID

If you don't have powerpath and need to get the LUN ID to device special file (dsf)/ disk device on HP-UX, try using the following switch on the syminq command (part of Solutions Enabler):

syminq -identifier device_name

example:

syminq -identifier device_name | head

Device Device

------------------------- ----------------------- ----------------

Name Num Vendor Array ID Name

------------------------- ----------------------- ----------------

/dev/rdisk/disk428 09B8 EMC *redacted* N/A

/dev/rdisk/disk429 09B9 EMC *redacted* N/A

Actually I think the default syminq output (without any switches) shows the lun id, but it’s hidden in the “device” “serial Number” column. Skip the first 3 digits in the column (part of the array ID). The next 4 digits (or so) are the Lun ID.

Example (lun ID in bold):

Symbolic links on HP CIFS/Samba 3.5.4

using symlinks on HP CIFS/Samba 3.5.4 can be an issue if the parameter unix extensions = yes (which is the default). Look up the man page for smb.conf for more info on it.

use the testparm -v command (-v = verbose), this will show ALL settings (built-in defaults) along with all the custom settings from your config file.

Since "unix extensions" only helps when using HP CIFS clients, IMO it should be disabled by default. so do this in the global section of smb.conf

when modifying the profile, only the parameters that are changing need to be listed; you don't need to re-do the entire syntax

three ways that work: first two only work if the ignite server and client are in the same ethernet broadcast domain (subnet).

  - last option gives fast boot time, first and second options requires less administration.

1. dbprofile -dn ignite -dhcp

2. dbprofile -dn ignite -dhcp -b "/opt/ignite/boot/nbp.efi"

3. dbprofile -dn ignite -sip IGNITE.IP.ADDRESS -cip CLIENT.IP.ADDRESS -gip GATEWAY.IP.ADDRESS -m NETMASK -b "/opt/ignite/boot/nbp.efi"

example - ignite IP 192.168.1.2,  client IP 192.168.0.2, gateway/router IP 192.168.0.1, netmask 255.255.255.0

dbprofile -dn ignite -sip 192.168.1.2 -cip 192.168.0.2 -gip 192.168.0.1 -m 255.255.255.0 -b "/opt/ignite/boot/nbp.efi"

to actually use the dbprofile:

lanboot -dn ignite

or to pick a specific NIC to boot from: lanboot select -dn ignite

to find list of NICs, run:

lanaddress

sometimes on NPARS, not all NICs show up, so do the following to re-connect the EFI drivers:

HPUX 11.31 lvm2

Wow LVM2 found in HPUX 11.31 has lifted a lot of burdensome limits on volume groups.  vgcreate automatically creates the  device group file; VGs are only limited by the MAX VG size you specify when creating the VG, using the -S option; hitting the max VG size is the only case where a backup/recreate/restore is needed.  Here's a list of helpful commands:

LVMP_CONF_PATH_NON_BOOT  found in /etc/lvmrc  (in March 2010 release)  allows lvm2 vg configuration file backups to an alternate location because of the large size of VG 2.X backups

lvmadm - (-t) displays limits of LVM1 and LVM2 VG 1.0 and VG 2.0 and up;  (-l) also lists the contents of /etc/lvmtab and lvmtab_p

lvmadm -l

--- Version 1.0 volume groups ---

VG Name /dev/vg00

PV Name /dev/disk/disk3_p2

        /dev/disk/disk2_p2

--- Version 2.1 volume groups ---

VG Name /dev/vgXX

PV Name /dev/disk/diskXXX

convert from legacy to persistent DSF: use vgdsf

/usr/contrib/bin/vgdsf –c vgXX

vgcreate using the new LVM2 VG2.0+ notation:

vgcreate -V 2.1 -s 16 -S 4t vgXXX /dev/disk/diskxxx /dev/disk/diskxxx

convert from VG1.0 to VG2.0+

The -r does a "review" to make sure the VG can be converted.

vgversion -V 2.1 -r vgXX

before the convert will run the VG has to be deactivated:

vgchange -a n vgXX

vgversion -V 2.1 vgXX

ioscan new options for persistent dsfs:

ioscan -m dsf /dev/disk/disk127

ssh without being prompted for password

if you have public keys on most of your boxes but not all and are

making skype portable

To make skype run on a usb flash drive or some other portable device follow the following:

 

http://www.gruups.com/usbskype/

 

First...Download the NEWEST version of Skype (Older versions won't work) and install it on any computer as normal.

Find the Skype.exe from where it was installed.
(Usually C:\Program Files\Skype\Phone\Skype.exe )

Copy the Skype.exe file to any directory on your USB Drive

In that new directory create a directory called "data"

Now create a file (with notepad) called "skype.bat"

Edit the "skype.bat" file and place the following line there:
skype.exe /datapath:"Data" /removable

 

/tmp on Solaris 10

On Sun Solaris 10, /tmp is a tmpfs type file system.  It is supposed to make reads/writes to the temp filesystem fast, but there are some caveats:

 

http://www.softpanorama.org/Solaris/Processes_and_memory/swap_space_management.shtml

Swap Space and the TMPFS File System
The TMPFS file system is activated automatically in the Solaris environment by an entry in the /etc/vfstab file. The TMPFS file system stores files and their associated information in memory (in the /tmp directory) rather than on disk, which speeds access to those files. This results in a major performance enhancement for applications such as compilers and DBMS products that use /tmp heavily.

The TMPFS file system allocates space in the /tmp directory from the system's swap resources. This means that as you use up space in /tmp, you are also using up swap space. So if your applications use /tmp heavily and you do not monitor swap space usage, your system could run out of swap space.

Use the following if you want to use TMPFS but your swap resources are limited:

Mount the TMPFS file system with the size option (-o size) to control how much of the swap resources TMPFS can use.
If you are close to running out of swap space, you can use your compiler's TMPDIR environment variable to point to a larger, real directory.
Using your compiler's TMPDIR variable only controls whether the compiler is using /tmp or not. It has no effect on other programs' use of /tmp.

putty command sender

Putty Command Sender:  http://www.millardsoftware.com/puttycs

Sends keystrokes to putty windows.  Filters allow selection of putty sessions/windows to which the commands are sent.  You can exclude/include and use wildcards in the filter.  I don't think it supports regular expressions other than * and ?  Allows arrow keys, control characters, and a lot more.

Be real careful when using this, experiment first on lab systems.

how to add a bulk load of putty sessions

add bunch of putty sessions.  This requires cygwin base install which includes the sed command.  Be sure to add \cygwin\bin to the path:
create a "template" putty session with all the settings you want.  go into the registry and export the session: HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions\session_name

put a list of machine names in test.txt

then in dos:

for /f %a in (test.txt) do type m.reg | sed -e 's/Template_NAME/%a/g'>> all.reg


These sessions can then be used in putty session manager or any of the other putty related tools.

differences trying to retain ownership/permissions on HP-UX and nfs

on HP-UX (by default anyway), you can change ownership of a file as a normal, non-root user. This means you can do a cp -p to copy files retaining permissions and ownership on HP-UX file systems. However, if using NFS, be aware that the underlying NFS server's operating system controls privileges to file ownership. Therefore most Linux/Solaris/NAS boxes that are NFS servers and mounted on HP-UX, will not allow a successful cp -p for retaining ownership (or chown by a normal non-root user).

Specifically it can be an issue on EMC Celerra NAS servers, but there's a way to change it:
To change this behavior you can change the Celerra server parameter, rstchown to 0, the default is 1.

Here's a copy someone posted: http://www.scribd.com/doc/6116381/Celerra-Network-Server-Parameters-Guide-5639-A03

contents:
Sets restricted file ownership.0 = Allow the owner of a file to change the file ownership or group ID to any other owner or group because chown and chgrp follow the less restrictive POSIX semantics.1 = Allow only the superuser to change the owner of a file. The current owner can change the group ID only to a group to which the owner belongs.This parameter applies to NFS, but not to CIFS.

contents of first link:
Here is how:

1. Format your USB stick from Windows: FAT, Quick, Default Allocation Size.

2. Download Grub4DOS from: http://download.gna.org/grub4dos/
Choose latest version. Here is the one I got: http://download.gna.org/grub4dos/grub4dos-0.4.4-2009-06-20.zip

3. Download Grub Installer from: http://download.gna.org/grubutil/
Choose latest version. Here is the one I got: http://download.gna.org/grubutil/grubinst-1.1-bin-w32-2008-01-01.zip

4. Extract them on your hard disk. Run: grubinst_gui.exe

5. Click DISK. Choose your USB stick. Go 2 boxes down and click REFRESH. On the PART list, choose "WHOLE DISK (MBR)". Make sure everything else is unchecked below.

If it says something about --skip-mbr-test, type: "--skip-mbr-test" without quotes in EXTRA box.

Click INSTALL. DOS box should pop up and tell you it transfered MBR.

6. Copy: file "grldr" from your extracted files to your USB stick.

7. Create a text file in the root of your USB stick and name it: menu.lst

Put inside:

title TRUECRYPT RESCUE DISK
find --set-root /tc.iso
map --mem /tc.iso (hd32)
map (hd0) (hd1)
map (hd1) (hd0)
map --hook
root (hd32)
chainloader (hd32)

And save the file.

8. Copy TrueCrypt Rescue Disk (the iso you created during system encryption) to root of USB and rename it to: tc.iso

If you don't have the iso, go to TrueCrypt program: SYSTEM > CREATE RESCUE DISK... Follow hte prompts and copy that file to USB and rename it to tc.iso

That is all.

( as of OS 3.0 ) To use it, go into the mail app and in the email to/cc/bcc fields you should see the backtick in the upper left on the symbols virtual keyboard. Then just copy and paste it wherever you need it.

password aging field

http://www.tech-faq.com/password-aging.shtml
http://www.cse.ohio-state.edu/~mamrak/CIS762/unix_encryption_tut.html


On non-trusted systems password aging is stored as part of the encrypted password each user's account in the system's password file.  The password field, which is the second field is divided in two by a comma.  The first portion, characters 1-13, is the encrypted password.  The second portion, after the comma (characters 15-18), is the password aging field for that account.
password aging field (characters 15-18) breakdown:
character 1: max weeks password is valid before expiration
character 2: min weeks password before password can change
remaining characters: last password change (in number of weeks since 1/1/1970)

the characters are Base-64, so it's kind of tricky.  See the above links for a conversion table for Base64.

calculate:
,N/TT

N = 25 weeks, 175 days max password lifetime
/ = 1 week, 7 days miniumum password before changing
S = 30
T = 31
31 * 64 = 1984
1984 + 31 = 2050 weeks since January 1, 1970 = 08/07/08

logname and utmp/utmpd problem

I've encountered the following problem a number of times:
ssh (or telnet) into a box, sometimes only occurs on a particular tty, like /dev/pts/1
$ logname logname: could not get login name
even though:
$ id
uid=101(me) gid=102(mygroup)

UPDATE for sshd issues:
update your version of SSH or HP patches; see the last couple comment on this ITRC Forum posting.
try changing UsePrivilegeSeparation to no in sshd_config: /etc/opt/ssh/sshd_config
UsePrivilegeSeparation no

then send a SIGHUP to sshd:
kill -s SIGHUP $(cat /var/run/sshd.pid)
end update

It seems like the utmp database is corrupt or not functioning properly. When logname gives the error message "could not get login name", then system doesn't know who I am, so it thinks I'm root (it writes root-root in the sulog file).

To fix it, I just stopped and restarted the utmpd daemon process: /sbin/init.d/utmpd stop ; /sbin/init.d/utmpd start

This problem sometimes causes logins to hang when processing /etc/profile, if logname is used in /etc/profile or another login script.

doesn't fail back to original active port because both ports have the same priority.

using Twitter with Google talk for your domain

http://www.kavinda.net/2007/07/31/HowToTwitterOnGTalkForYouDomain.aspx  explains how to add the necessary DNS SRV records to your zone in order to twit via Google chat.  This is necessary to get twitter to work with Google Talk when your using Google Apps for your domain.

Go to the Chat section under 'Service Settings' when in the administration 'manage this domain' page for your domain.  a link will be to: http://www.google.com/support/a/bin/answer.py?answer=60227&hl=en   But you'll need to follow the above instructions as well (maybe, haven't tried yet)

HP APA (auto port aggregation)

HP-UX has no built in lan aggregation or failover; I know - it's a damn shame.  (note: serviceguard does have a local lan failover mode)  HP APA (Auto Port Aggregation).

Be sure to do the configuration from a console connection or connect from a NIC that won't be involved in APA, otherwise you'll drop and may not be able reconnect over tha lan if you screw up the config.

commands to configure it:
lanqueryconf
lanapplyconf
lancheckconf
landeleteconf

Here's my quick and dirty version of creating a lan failover group:

--- APA configuration --
added the following line to /etc/rc.config.d/hp_apaconf
HP_APA_USE_SYSLOG=1

add the following to: /etc/rc.config.d/hp_apaportconf
HP_APAPORT_INTERFACE_NAME[0]=lan5
HP_APAPORT_CONFIG_MODE[0]=LAN_MONITOR

HP_APAPORT_INTERFACE_NAME[1]=lan6
HP_APAPORT_CONFIG_MODE[1]=LAN_MONITOR


 /sbin/init.d/hplm stop
 /sbin/init.d/hpapa stop
 /sbin/init.d/hpapa start
 /sbin/init.d/hplm start

create ascii file:
lanqueryconf -s

change priority of both primary and secondary to the same value, so that failback doesn't occur.
vi /etc/lanmon/lanconfig.ascii

check validity of ascii file:
lancheckconf

apply the changes to the binary file:
lanapplyconf

check config:
lanscan and lanscan -q and lanadmin -x -v PPA  and netstat -in



Once it's configured, here are some useful commands for looking at the status:
real status of ports:  lanadmin -x -i 900 
load balancing mode:   lanadmin -x -l 900
verbose config:        lanadmin -x -v 900

Where 900 is the PPA number for the apa/failover group

serviceguard error renaming hosts

The following is from renaming hosts or changing their IP addresses in a SG cluster.  In addition to changing all the cluster configuration files (cmclnodelist, cluster ascii, package ascii and control files) from the old names to the new names, you also probably need to delete /etc/cmcluster/cmclconfig (the cluster binary config file).  The old IP address are "stuck" in there and cmcheckconf or cmapplyconf  won't proceed without deleting the cluster binary file.

If you don't delete it, here's the message you will receive when running cmapplyconf or cmcheckconf:

Checking nodes ... Done
Checking existing configuration ... Done
Warning: Unable to get configuration for cluster CLUSTER_NAME
Error: Node HOSTNAME is refusing Serviceguard communication.
Please make sure that the proper security access is configured on node
HOSTNAME through either file-based access (pre-A.11.16 version) or role-based
access (version A.11.16 or higher) and/or that the host name lookup
on node HOSTNAME resolves the IP address correctly.

single vs. dual core in HP-UX

use machinfo:  /usr/contrib/bin/machinfo

the following hints are from: http://forums11.itrc.hp.com/service/forums/questionanswer.do?threadId=1209686

Single-core processors ======================
processor family: 31 Intel(R) Itanium 2 Family Processors


Dual-core processors ====================
processor family: 32 Intel(R) Itanium 2 9000 series
or
processor family: 32 Intel(R) Itanium 2 9100 series


So, processor family 32 means dual core;  processor family 31 means single core.

ECC agent fails or hosts don't appear

the hosts don't appear in the EMC Control Center (ECC) master server, or one does but then is replace by another. Sometimes the agent starts, but then unexpectedly quits/dies. If you clone your boxes, exclude /var/ECC or else!

Otherwise just: stop the agent; nuke /var/ECC ; restart agent is the fix for this issue it seems


open a http://powerlink.emc.com account and see the article: "Hostname change not reflected in ControlCenter console." EMC doc ID: emc139067

Looks like you also need to remove a couple more files in /usr/ecc/exec any files with the extensions .lck, .port, .uid and .comfile
