Re-entering the server serial number and product ID
After you replace the system board, you must re-enter the server serial number and the product ID.
1. During the server startup sequence, press the F9 key to access RBSU.
2. Select the System Options menu.
3. Select Serial Number. The following warning is displayed:
WARNING! WARNING! WARNING! The serial number is loaded into the system
during the manufacturing process and should NOT be modified. This option
should only be used by qualified service personnel. This value should
always match the serial number sticker located on the chassis.
4. Press the Enter key to clear the warning.
5. Enter the serial number and press the Enter key.
6. Select Product ID.
7. Enter the product ID and press the Enter key.
8. Press the Esc key to close the menu.
9. Press the Esc key to exit RBSU.
10. Press the F10 key to confirm exiting RBSU. The server will automatically reboot.

This is the official instructions in the manual. I applied the following steps:

1 – Advanced Options

RBSU 1 Serial Number

2 – Serial Number

RBSU 2 Serial Number

3 – Inserting the new one and then exiting

RBSU 3 Serial Number

Suse Linux 10 SP2 – rpmlib(PayloadIsLzma) <= 4.4.6-1 is needed by

If you try to install or update a package and the following error message appears

root@suselinux10sp2:~ # rpm -Uvh supportutils-1.20-81.1.noarch.rpm
warning: supportutils-1.20-81.1.noarch.rpm: Header V3 DSA signature: NOKEY, key ID 823559f0
error: Failed dependencies:
rpmlib(PayloadIsLzma) <= 4.4.6-1 is needed by supportutils-1.20-81.1.noarch

You need to verify if the compression method is supported by rpm.

root@suselinux10sp2:~ # rpm —showrc | grep Payload
rpmlib(PayloadIsBzip2) = 3.0.5-1
rpmlib(PayloadFilesHavePrefix) = 4.0-1

In this machine, only bzip2 is supported. One work-around is to update the rpm package before trying to install/upgrade the package where the error message appeared.

IBM Rational ClearCase mount.mvfs: Too many open files in system

There is a Linux host where ClearCase can’t mount any more VOBs

mount.mvfs: Too many open files in system

Reading this note on http://www-01.ibm.com/support/docview.wss?uid=swg21234500#linux says the following:
The number of VOBs that can be mounted simultaneously under Linux is 1022, but this limit can be increased by configuring your MVFS. After you edit the mvfs_param.c file as described below for the kernel version of your system, rebuild and reinstall the MVFS or vnode module using the instructions contained in the README.txt file in the directory containing mvfs_params.c.

This is exactly the case on my system

root@linux:~ # df -h | grep vbs | wc -l
1022
