Unreadable disks

We are installing a new AX4-5i that will be connected to one server running Win2003 SP2 x64 Edition. The connection is made via a QLogic QLE4060C; firmware version is 3.0.1.33 and driver is 2.1.4.19 (STOR wx64) which are both current.

 

The storage unit has the following drives installed:

Disks 0 - 3: 133GB SAS

Disks 4 - 11: 268GB SAS

 

The problem that we are having is that all virtual disks built on particular pools show up in Windows as being "Unreadable". The crazy part is that the problem appears to only happen with virtual disks built on even-numbered drive pools.

 

To see why I say that here are the configurations I've tried.

Config #1

Disk Pool 1: Disks 6, 7, 8; RAID 5; 1 virtual disk

Disk Pool 2: Disks 9, 10, 11; RAID 5; 1 virtual disk

Disk Pool 3: Disks 0, 1; RAID 1/0; 1 virtual disk

Disk Pool 4: Disks 2, 3; RAID 1/0; 1 virtual disk

Disk Pool 5: Disks 4, 5; RAID 1/0; 1 virtual disk

 

Result: The disks on pools 2 and 4 showed up in Windows as "Unreadable"

 

Config #2

Disk Pool 1: Disks 6, 8, 10; RAID 5; 1 virtual disk

Disk Pool 2: Disks 7, 9, 11; RAID 5; 1 virtual disk

Disk Pool 3: Disks 0, 2; RAID 1/0; 1 virtual disk

Disk Pool 4: Disks 1, 3; RAID 1/0; 1 virtual disk

Disk Pool 5: Disks 4, 5; RAID 1/0; 1 virtual disk

 

Result: The disks on pools 2 and 4 showed up in Windows as "Unreadable"

 

After seeing the alert regarding our lack of a hot backup disk I assigned disk 11 as the hot backup and tried something new.

Config #3

Disk Pool 1: Disks 6 - 10; RAID 5; 4 virtual disks

Disk Pool 2: Disks 0 - 3; RAID 1/0; 4 virtual disks

Disk Pool 5: Disks 4, 5; RAID 1/0; 1 virtual disk

 

Result: The disks on pool 2 all showed up in Windows as "Unreadable"

 

Subsequently I deleted and recreated Pool 2 with the following configs:

Disks 0 - 3; RAID 5; 4 virtual disks

Disks 0 - 2; RAID 5; 4 virtual disks

The results were the same: all four disks in the pool were "Unreadable" by Windows each time.

 

This is where I'm at currently:

Disk Pool 1: Disks 6 - 10; RAID 5; 4 virtual disks

Disk Pool 2: Disks 0, 1; RAID 1/0; 3 virtual disks

Disk Pool 3: Disks 2, 3; RAID 1/0; 3 virtual disks

Disk Pool 5: Disks 4, 5; RAID 1/0; 1 virtual disk

 

Result: The disks on pool 2 all show up in Windows as "Unreadable"

 

There don't appear to be any issues anywhere else - the storage unit is not showing any alerts and the HBA card is recognizing all of the LUNs correctly. Is there any reason that a specific pool would cause problems with Windows being able to read the associated virtual drives?

 

Thanks for any help with this. :)
