Unable to access RAID array from CentOS5

Hi all, first post, please be gentle...

Our Solaris box has gone down badly, leaving us with with the Sun RAID array that was attached to it intact but inaccesible.

I've connected the Array to our CentOS server via SCSI, the array device is detected, as shown by dmesg:

scsi2 : ioc1: LSI53C1030 C0, FwRev=01032700h, Ports=1, MaxQ=255, IRQ=66
  Vendor: SUN       Model: StorEdge 3310     Rev: 421E
  Type:   Enclosure                          ANSI SCSI revision: 03
 target2:0:1: Beginning Domain Validation
 target2:0:1: Domain Validation skipping write tests
 target2:0:1: Ending Domain Validation
 target2:0:1: FAST-80 WIDE SCSI 160.0 MB/s DT (12.5 ns, offset 62)
However, 'fdisk -l' doesn't show any partitions as a result, and I can't find any clues as to whether instances for it exist in '/dev'.

I'm at a complete lost of how to proceed, until I can see it in /dev I've no way of moving towards mounting the partitions.

If anyone has any hints on things to try to keep me moving on this I'd really appreciate it!

I suspect that the array is setup with GPT, so fdisk won't necessarily see it. I'm not sure CentOS, or your version has GPT support compiled in. See

Unfortunately, AFAIK CentOS 5 has GPT support, but I'll definitely investigate further.
