G'day Nightmare,
Not at all, thanks for the input.
I did know that there were issues with the some SAS/SATA Raid controllers with the ES.2 (didn't know it was specifically the intel IOP though), that's why we went with the Adaptec 5405 which did support the Seagates....
It's amazing, if you read the post it specifies the 2xxx and 5xxx cards need AN05 and the others 3xxx etc need SN05.
Makes a mockery of "Unified" controllers, since the main reason we have stuck with the Adaptecs was because we could then easily shift Arrays from one server to another.
The symptoms are so similar, I wonder if it is possible to have the drives report the AN05 firmware but not actually have it installed.
ie we did the updates, but I wonder if something was screwy with the process.
Nah what are the chances that they don't do a CRC? :-)
