Today I faced challenge where I had to reinstall some IBM xSeries servers in a datacenter far far away using PXE boot. These servers did not have an RSA\/RSAII card, but that is really not a problem using PXE. I prepared the kickstart on the first of the servers and did some reinstalls to get it right. And then I issued an ipmi command to reboot the rest of the servers. … and then nothing happened. Well the rest of the servers rebooted back into the old OS instance. It was ofcourse an issue with the boot order in the BIOS on the servers.<\/p>\n
Now what? Either drive to the DC or call someone there to get it fixed. …. or use the IBM ASU tool to change the BIOS settings from within an OS instance. It is quite a useful tool<\/p>\n
Without further ado<\/p>\n
