Storage disk startup sequence

Hello everyone.

I'm using an HP cluster. In device manager on any node, it reports the disks in the storage as being "caught" first than those in the local server.  

So, when I should see the configuration:
Local server disks
disk0 - c:
disk1 - p:  
Storage disks
disk2 - l:
disk3 - y:
disk4 - h:
disk5 - q:

I see it upside down:
Storage disks
disk0 - q:
disk1 - h:
disk2 - y:
disk3 - l:
Local disks
disk4 - c:
disk5 - p:

Checking boot.ini and active disk partition (diskpart), seem like they are ok. No errors being entered in event log.

Just wanted to know what may have caused the inversion. How could my server be checking the storage drives first?

Thanks in advance

I suspect the lightpulse HBA is in a lower PCI bus/slot number than your RAID controller, does boot.ini list it as booting off multi(1) ?

Info on lightpulse HBA (as seen on Device Manager >> Properties):
PCI Slot 3 (PCI bus 6, device 1, function 0)

Raid controller info (Smart Array 5i; as seen on Device Manager >> Properties):
PCI bus 1, device 1, function 0

Info on boot.ini:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Enterprise" /fastdetect
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Windows Server 2003, Enterprise - Backup" /fastdetect
C:\CMDCONS\BOOTSECT.DAT="Microsoft Windows Recovery Console" /cmdcons

Again, all seems okay here...

Do you have the high availability kit, i.e. dual HBAs and securepath? That messes up with the disk numbers and signatures making it really hard to get the cluster to come up after a restore.

Yes I do mate :)

Could you give me some more info on the subject, please? For example, would a re-instalation solve this? If so, what steps should be taken?

Or if U think a re-instalation wont do much good, what should I expect in terms of behaviour for the cluster? Until now, its working as normally as any other machine - should I pay attention to something?

I haven't got much info, http://support.microsoft.com/default.aspx?scid=kb;en-us;886800 relates to the issue but if your cluster is already up I can't see how the signatures/disk number scan have been re-written. http://support.microsoft.com/default.aspx?scid=kb;en-us;293778 says there's also a new version of ftdisk.sys for win2000 for the same problem but I wouldn't replace it if everything is up and running, you may not be able to restore a cluster disk from full backup but you can certainly rebuild the cluster and restore the data.

That's not exactly what happened to me, what happened to me was I was meant to change the disks for bigger ones and was prepared to rewrite the signatures to match after finally finding dumpcfg.exe on the web (MS lists it in the res kit but not available to download) and also had a copy of clusterrecovery.exe (which was downloadable) but the drive numbers as well as the signatures had been re-written and although they showed up in the right order in disk administrator the registry had different disk numbers for them than before. - never did get it running again but had to build a new cluster instead.
