Disk sequence


I have two raid cards on the same machine (raid 1 & 5).

Raid 1 shows up as sdb and raid 5 shows as sda.

I want to install the OS on raid 1, but the fact that it shows as sdb it just don't look right. Is there anything I can do to make it as sda?

Swap the slot of the pci cards?

I think this is just comestic.

This shouldn't matter at all to the system. Probably swapping the PCI slots would rearrange the drives to suit you, though I don't think you should even bother.

By the way, I just moved my system from sdc2 to sde1. Sda is nothing but a data drive, as is sdb, and sdc just got cycled out of service (used to be system drive).

I doubt that that would work to swap the drive order. unless both raid cards are addressed by the same driver ?? otherwise:

In order to get this to work you probably would have to rearrange the order in which the scsi drivers are loaded.

But as jiml8 says, it doesn't matter to systems on which your main (boot and/or root) partition resides. It's important that your system BIOS is able to find the raid1 array to actually boot the OS from.
