Good post by Brian Smith (thank you)
This is a small update to my previous posting on mapping Virtual SCSI disks easily via a script. As input to the script you give it the LPAR name, the label for the mapping, and the LUN serial number, and the script will find the VIO servers, figure out which vhost adapter on each VIO matches up to the LPAR, and find the correct hdisk to map based on the serial number on each VIO server. The script just prints out the command that needs to be run to map each LUN (it doesn’t map anything itself), and then you can copy and paste the command yourself to actually map it.
