CentOS - Oct 2007 - Trying to recover data off SATA-to-SCSI external 2TB ARRAY

Original the array was attach to an HP server via a Smart Array
Controller.(which I didn't setup, I just inherited the problem)
This controller no longer recognizes the array even though the front panel
of the array indicates its intact.
I then took the array and plugged it into my Centos server and it recognized
it ...
cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: XD-T112- Model: 212R Rev: R0.0
Type: Direct-Access

But with errors
 In dmesg have this:
sda: Mode Sense: bf 00 00 08
SCSI device sda: drive cache: write back
sda: unknown partition table
sd 0:0:0:0: Attached scsi disk sda

I have no experience with the Smart Array Controller, just what I read the
past couple of days.
Here's how it was mounted on the HP server
/dev/cciss/c0d1 /stor02 ext3 defaults 1 1
Is there a way I can get the data off the array with my Centos server?
Any help/suggestions/tips would be greatly appreciated, I've hit a brick
wall.

The partition table could be hosed. You might want to consider sending the 
unit out for recovery if it is critical data and you have no backups.
You might be able to scan it with testdisk and see if it finds anything.

Or try the tools from the array manufacturer if they have any.

Those are not errors. But it doesn't seem to have a partition table (see 
below)

Ah, they put the ext3 directly on the device. Consistent with the above data.

Try "mount -oro /dev/sda /mnt/tmp" (or whatever) or just see if
there's a
superblock there with "tune2fs -l /dev/sda".

he has a hardware raid set of drives originally from a HP/Compaq 
SmartArray controller, now connected to a simple non-raid scsi 
controller.   sorry, thats not gonna play no way no how.
