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)

Help USB to serial adapter

I'm looking for some advice:  anyone out there that uses a USB to rs232 serial adapter to connect to the local console port on HP9000 boxes successfully on several old and new models?

I bought a USB-serial adapter at best buy, installed the drivers and connected it to a local console port of several rp2450.  I can only receive screen updates from the console, but my keystrokes (transmit) isn't working from the PC to the console port.  However, on a new BL860c blade and an L1500 I can both send and receive via this usb-serial adapter.

Do you have a clue what could be the problem?  If anyone reading this blog knows, please post a comment!  Thanks  >/dev/null

GSP firmware notes

If you aren't locally connected to a GSP and want to upgrade the firmware, you can do it via the lan console. You'll have to either be connect via local console or via the GSP's internal port.

All of the following information was gleaned from:
http://forums12.itrc.hp.com/service/forums/questionanswer.do?sortPointsFlag=1&threadId=836831&admit=109447627+1200601321780+28353475

to get the version of the GSP: the 'he' command will show version in the first line of output:
Hardware Revision 8 Firmware Revision A.01.10 May 24 2001,11:05:55


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
mknod tty1p0 c 1 0x010000

vi /usr/lib/uucp/Systems and add the following line exactly:
gspiport Any;5 gspiport,f900 - ''''\r\d\r\d\r ogin:-BREAK-ogin: uucp asswrd: uucp-BREAK-ogin: uucp asswrd: uucp


vi /usr/lib/uucp/Devices and add the following exactly:
gspiport tty1p0 - 9600 direct

connect via:
cu -l /dev/tty1p0

do the firmware upgrade via the XU command.

to exit the cu command type the following two characters: ~.

rename file extensions easily in Unix

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:
for i in *.txt
do
mv $i ${i%.txt}.ascii
done

HPUX: lpadmin - can't open member file

problem adding a printer on HPUX (10.20 in my case, but this error occurs on all versions)
lpadmin: can't open member file

one possible cause:
/etc/lp needs to be owned by the 'lp' user id.

fix:

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

make Firefox in Ubuntu look much better

The look and feel of web pages in FireFox in Ubuntu (possibly other Linux distros) by default stinks (in my opinion).  Trying to convert myself from Windows solely to Linux, this has been hard, but I found a way to make the fonts look really good in Firefox (improves the entire experience):
http://www.ubuntuforums.org/archive/index.php/t-91280.html

Change the fonts in preferences:

where it says, serif, select 'Bitstream Vera Serif'
where it says, Sans-serif, select 'Bitsteam Vera Sans
where it says, Monospace, select 'Bitsteam Vers Sans Mono'

My switch from Windows XP to Ubuntu Linux:

ll /dev/dsk | grep 052200

0x1f052200
The First two hex digits (1f - 31 decimal) denote the major device number. If you do an lsdev, you will note that 31 is the scsi disk block device.

After that it decodes as follows the following hex digits:
05 - c5
2 - t2
2 - d2
00 - the last two minor device digits are driver specific
But yours is: SCSI Block Disk Device, c2t2d2

the last 6 digits are the minor number of the device.

nfs / rcp / CDE issue

This problem seems to keep happening since this box was upgraded to 11.11.  The rpc/nfs daemons seem to restart at 00:05.  Killed all fin_wait_2 connections and restarted nfs/rpc daemons.:

stuff=$(/usr/bin/printf "%.2x%.2x%.2x%.2x%.4x%.2x%.2x%.2x%.2x%.4x\n" \
$(/usr/bin/netstat -an -f inet | /usr/bin/grep FIN_WAIT_2 | \

solution:  It was being caused by a cronjob stopping and starting rpc, but was not doing it correctly.

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.
