CentOS - yum update failed - Retrieving GPG key ...

While using yum to update CentOS

Get the "Retrieving GPG key .." error, files get downloaded but fail to update

I solved the problem by get the RPM-GPG-KEY from the first CD of the installation media. In my case, it is "RPM-GPG-KEY-CentOS-5"

Need to import this key to RPM's DB, run the following command as root

rpm --import RPM-GPG-KEY-CentOS-5

VM everywhere

Saw the following headline a few days ago "VMware stock loses 33% on revenue"

Apart from Microsoft and VMWare, even Oracle is offering VM software for free(I wonder when Oracle will start selling burger !)

IBM ServRaid-7k "Wrong SCSI controller found - 3E22"

Found this error when install the IBM ServRaid-7k

Wrong SCSI controller found - 3E22

The problem is related to the on-board HostRAID. We have to disable the the on-board HostRAID first. Press "Ctrl-A" during bootup and use the SCSI utility to diable HostRAID

If you want to switch back to the HostRAID from ServRaid-7k. You have to enable the SCSI device manually in the BIOS since it will be disabled automatically after the ServRaid-7k is removed; otherwise, not even the SCSI will work.
