Some Fibre Channel HBA models found on HP Proliant running Linux

I was updating some servers and this is a small list that I created to help to update the firmware

Problems updating firmware on QLogic QLE2460, QLE2462 and QMH2462 on HP Proliant

I’m having problems updating the firmware on fibre channel HBA cards QLE2460, QLE2462 QMH2462.

For example, this server has a single channel 4Gb QLE2460 and dual channel 4Gb QLE2462

I think the solution will be to update the firmware offline using the HP SPP DVD and selecting Firmware update

Server booting correctly but file /boot/grub/grub.conf is missing

I was checking a server that didn’t have the file /boot/grub/grub.conf but it was booting without any issues.

The server is a Proliant Gen9

libstdc++.so.6 is needed by hpacucli-8.70-8.0

I have a Suse 9 that is not installing the hpacucli

In this server it is a local disk so it was added to the multipath blacklist

root@linux:~ # vi /etc/multipath.conf
blacklist {
devnode “^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*”
devnode “^hd[a-z]”
devnode “^sd[ab]$”
devnode “^cciss!c[0-9]d[0-9]*”
}

If you are in a VMware host, you can safely disable this module.

root@linux:~ # cp /var/opt/OV/bin/instrumentation/mp_mon.cfg /var/opt/OV/conf/OpC/

In the configuration file /var/opt/OV/conf/OpC/mp_mon.cfg set disable to yes

root@linux:~ # vi /var/opt/OV/conf/OpC/mp_mon.cfg
disable = yes

Suse Linux 9 boot – cciss: cmd f6b80498 has CHECK CONDITION byte 2 = 0x3

cciss
At startup I was receiving this message

cciss: cmd f6b80498 has CHECK CONDITION byte 2 = 0x3
cciss: cmd f6b80000 has CHECK CONDITION byte 2 = 0x3

I found that this is a media error. Since I rebooted because the filesystem / became read-only that made sense.

I ended up reinstalling this server

Remove the graphical screen with progress bar in Red Hat Enterprise Linux and Suse

Edit file /boot/grub/grub.conf or /boot/grub/menu.lst and on the line that contains the word kernel, remove the word splash or rhgb (Red Hat Graphical Boot) from this line.

You will boot in text mode until it is time to transition to graphical mode otherwise you will remain on text mode.

Use this to check all console messages when booting. Useful if you need to connect remotely and pressing Esc or F2 fails

If you need to check, boot the kernel using the option splash=off or remove rhgb. You also can use consoleblank=0 to not turn off the screen.

How to remove files with strange characters

To remove files that contain symbols and unknown characters, list the files with ls -li and take note of the inode number

root@linux:~ # ls -li
total 4420
2495260 -rw——- 1 root root 13810 Jan 28 2011 ????!
2495249 -rw——- 1 root root 13810 Jan 28 2011 ????!

Run the find command and see if it shows the desired file

root@linux:~ # find . -inum 2495260
./????!

And then complete the find command to search, find and remove the file.

root@linux:~ # find . -inum 2495260 -exec rm -i {} \;
rm: remove regular file `./20\36406\b!’? y

Changing HP Proliant serial number

If you want to do it online, with some tool under Linux, it can’t be done.

Unless you have an HP Proliant 100 series, you need to enter the RBSU and change the serial number.

Setsys Utility for HP ProLiant 100 series G5 and G6 Servers

Always remember to change the serial number back when replacing the system board.
