1, if you are running a windows cluster, you need to use the LSI Logic
SAS controller, not the paravirtual.
This is true if the cluster is Windows 2008, not for Windows 2003.
2. Why would you need to set a boot order for more than 1 or 2 drives?
You should make sure the devices are configured with the ID you want
them to have when you are adding the virtual machines. Make sure the
SCSI id matches how you want the drives to be recognized. You don't
have a boot image on more than 1/2 drives, do you?
It's not that I want to modify the boot order, but after adding the new drives/controllers these changed the default boot order, therefore I need to be able to re-select 0:0 as the boot drive.
