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

HPUX verses Solaris

An SA's comparison of HP-UX verses Solaris: 

http://www.loudermilk.org/software/solaris-hpux.html

 

I'm still biased to HPUX, although this guy makes some compelling arguments: DTrace, p*/process command tools, hardware (path) identification, log rotation, shadow file, patch numbering.  especially the Dtrace and /usr/proc/bin tools.

 

 

ssh without being prompted for password

if you have public keys on most of your boxes but not all and are
running a script against all of them, but don't want the script to
just pause at the password prompt, then specify the
"PreferredAuthentications" option:

ssh -o PreferredAuthentications=hostbased,publickey

I couldn't get the PasswordAuthentication=no option to work, so the
above saved me

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.

allow control D keyboard sequence to work

the EOF key (generally control D) gets trapped/ignored by the shell on some systems.  Here's how to turn that off:

 

 

hit control-D
server$ Use 'exit' to logout

server$ set -o | grep ignoreeof
ignoreeof        on

server$ set +o ignoreeof

server$ set -o | grep ignoreeof
ignoreeof        off

server$ hit cntl-D

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.

adding secondary IP interface and IP index number to APA

just put the IP in netconf using the Physical PPA lan port (like normal), then when APA starts, it will bind it to the APA port
INTERFACE_NAME[1]=lan0:1
IP_ADDRESS[1]=1.2.3.4
SUBNET_MASK[1]=255.0.0.0
INTERFACE_STATE[1]=up

if adding a secondary IP once APA is already running: bind it to the APA PPA (lan900)  as follows:

and to skip iso check use the /noisocheck or /n  switches on truecrypt or mount the ISO using a virtual cd driver


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.

Backtick grave accent ` iPhone

The backtick (grave accent) ` character is missing from the iPhone and iPod touch normal keyboard layouts. ( 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.

It might be helpful if a bunch of us complained about this missing key on the iPhone and iPod touch keyboards - leave feedback about the missing backtick/grave accent character at: http://www.apple.com/feedback/iphone.html

Really stupid for them to have it on the email address fields even though it's an invalid char for email addresses.

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.

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.

ECC agent fails or hosts don't appear

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

route add default 192.168.1.1

ping 129.168.1.1

to reuse IP on different interface, unload the tcpipv4 driver, find the driver handle first:

create virtual media iso file

the following was derived from http://www.docs.hp.com/en/5991-6250/ch04s01.html

create an ISO file suitable for EFI environment using the Virtual Media option on the HP BL860c blade servers

in linux:
create a boot image big enough to fit the files you want on the CD (5MB example):
dd if=/dev/zero of=/tmp/boot.img bs=1024 count=5000

make a fat file system on it:
mkfs.msdos /tmp/boot.img

mount it:
mount -o loop -t msdos /tmp/boot.img /tmp/bootcd

copy any files needed into the mount point (/tmp/bootcd)

unmount the device:
umount /tmp/bootcd

create the directory structure to hold the dos file system:
mkdir -p /tmp/isofolder/boot

copy boot.img to the directory created above

create the iso file:
mkisofs -o mynewiso.iso -b boot/boot.img -c boot/boot.cat -no-emul-boot /tmp/isofolder
(optional -J and -R, joliet and rock ridge extensions)

note: from the EFI, only the msdos file system (boot.img) will be usable, the rest of the image will only be fully usable once the OS boots.  (HP-UX only supports virtual media on 11.23 Dec 2007 and Higher)

to access the GSP via the "internal port", which might not work on all GSP versions:

create the device file for the gsp internal port, delete device file when done for security reasons:
cd /dev

In dos you could:
move *.txt *.cvs

but the wildcard characters don't work that way in unix. You must do something like the following, where EXT1 is the original extension and EXT2 is the new one:

for i in *.EXT1
do
mv $i ${i%.EXT1}.EXT2
done

for example: to rename all .txt files to .ascii run the following shell script:

Naviagent not responding on unix host

Had two hosts that were not responding to navisphere, "agent is unreachable" or some bable...

on each host there was a /agentID.txt file that the agent reads before re-creating the /etc/log/HostIdFile.txt     The purpose of agentID.txt is to make naviagent bind to a specific IP address on a multi-homed system.  The IP address listed in the file doesn't need to exist on the system, it uses the IP without verification.

I stopped the agent, deleted both HostIdFile.txt and agentID.txt, then started the agent and it now is using the correct IP address in HostIdFile.txt

NFS exports to PC clients on EMC Celerra

Doing NFS exports to a PC client normally requires and authentication daemon running on the host system: pcnfsd on unix systems, just referred to as pcnfs on EMC Celerra   So it's more complicated than setting up NFS for Unix clients.

do a powerlink (powerlink.emc.com) search for: pcnfs celerra
look for a pdf document titled: Configuring NFS on Celerra
one of the appendixes: NFS Authentication for PC Clients

There's also a primus article regarding pcnfs: emc43806, below is the gist of the article:

# Set up a user account.
#     Open the /nas/server/server_x/netd file with a text editor, add pcnfs on a separate line, and save the file.
#     Where x is the number of the Data Mover.
#     Reboot the Data Mover.
#     Export a file system for the user(s) to access.
#     On the PC, launch the PC-NFS. Refer to the vendor's respective user manual for details on what is required
          at this point for setup and/or login.
#     Enter the username and password as required by the software package.

Doing an remsh or rlogin and receiving the following message:  "There is no passwd entry for you"   means that something in the local password file is screwed up.   In my case, a daemon was changing it's password entry and kept adding ....,  to the password field until it started to span multiple (10) lines in the password file.  Any system call that would search the passwd file would stop at the screwed up entry.  Removing and fixing the messed up entries solved the problem.

logname error in rlogin session on particular tty

when you rlogin and your tty is pts/0 (/dev/pts/0) you might get the following message when trying to execute logname:

logname: could not get login name

It appears that rlogind doesn't update /etc/utmp This of course appears to be intermittent if you have several clients doing rlogins, the first one that uses /dev/pts/0 will have the problem, the other will probably be fine. This is more of a problem if you are using the logname command in something like /etc/profile

Only noticed this on 11.23 (both IA and PA platforms). Both had PHNE_32818 installed. A possible fix is PHNE_33792, but I couldn't test it. A workaround is to use the variable $LOGNAME instead of the command logname.

Error: IP netmasks don't match, interface lan0 on node0
Error: IP netmasks don't match, interface lan0 on node1

but if your netmasks do match properly and currently in netconf, then the cluster binary file needs to be deleted and recreated from the ascii file.

get serial number of server hardware in Linux

In Redhat Enterprise or maybe other linuxes to poll the serial number of the server or workstation hardware from the bios using dmi:
dmidecode

May have to install the package from repositories.

EMC Clariion array - using powerpath vs pvlinks

I think I've found the answer to whether or not we should use Pvlinks when configuring our volume groups in HP-UX - the answer being no.  It's only recommended to use alternate links when booting from a storage array, which we don't do on any of our HPUX hosts.

From the powerpath admin guide:

EMC recommends using LVM alternate links (PVLinks) when you
boot from a storage system. If the primary path fails, an automatic
switch to the alternate path occurs. If PowerPath is not installed,
using alternate links increases availability in the event of hardware
problems.
PowerPath uses alternate links as part of its boot/root failover
strategy, but not for load balancing, path prioritization, or other
PowerPath-related reasons. Thus, EMC recommends that you use
LVM alternate links when booting from a storage system. Otherwise,
EMC recommends disabling PVLinks when using PowerPath.

powerpath check force: "Cannot remove device that is in use"

removing some ports on a clariion on a HP-UX host running service guard, I received the following:
$ powermt check force
Warning: CLARiiON device path c13t2d3 is currently dead.
Cannot remove device that is in use: c13t2d3

Powerpath is pretty darn smart; the last port 0 linked to a disk device was part of the same lvm volume group as one of my cluster lock disks.  It wasn't even listed in as the lock disk for my cluster (in the cluster ascii file), but it was in the same volume group that the lock disk was in.

I had to stop the cluster services on the node, then powerpath allowed me to remove the connection.  This node of the cluster is currently the failover node, so I was able to bring er down without any impact.

vgscan not working / ignite not recreating volume groups

I encountered a problem the other day with ignite not recreating the volume groups properly - it was caused by a component of service guard that was stuck on that machine.  For some reason (maybe because serviceguard was once installed on the box), the file /dev/slvmvg (serviceguard file for shared volume groups) also prevented vgscan from working.  Once I removed the file, vgscan created the volume groups without a problem.

gig card on hp-ux 11.00 doesn't keep speed/duplex setting

A 1000Base-T card in an 11.00 box was giving me grief.  the switch port was set to 100 full duplex, but the card kept staying at AUTO even though the speed/duplex was changed via sam and verified in the /etc/rc.config.d/hpgelanconf file; that, of course, cause collisions and a bunch of network errors because the card negotiated 100 half duplex.  There's a patch that fixes the issue:  28995   make sure the config file has the speed and duplex value in uppercase:

HP_GELAN_SPEED[0]=100FD

swinstall and rpc exception communications error

mkboot complains about logical volumes when none exist

$ mkboot /dev/dsk/c2t6d0
There appear to be non-boot logical volumes on this device.
Overwriting them could destroy all the data on this device
Should the logical volumes be overwritten [y/n]? y

solution:
because PV isn't marked as bootable.   pvcreate -B /dev/dsk/c2t6d0
or
PV belongs (or thinks it does) to a volume group already.  (tread lightly here!):
Fix by using the -f (force) option:  pvcreate -Bf /dev/dsk/c2t6d0
