Hello everyone,
I'm in the dark here.
I seem to have a bit of a problem with a RAID1 I have configured on the 3ware 9650SE-4LPML.

from it's 4 ports I have created 2x RAID1 arrays. (OSarray and DATAarray)
I seem to be losing the 1 of the 2 OSarray disks. The same one always.
After a restart, on the 3ware bios screen I will see the disk present but 'not in use' in the array and the array will be degraded.
once I start the rebuild process, the disk will disappear ('not present') and dmesg will output:
Quote:
3w-9xxx: scsi0: AEN: INFO (0x04:0x000B): Rebuild started:unit=0.
3w-9xxx: scsi0: AEN: WARNING (0x04:0x0019): Drive removed ort=0.
3w-9xxx: scsi0: AEN: ERROR (0x04:0x0002): Degraded unit:unit=0, port=0.

restarting the pc will probably show the disk again and after I start the rebuild the disk will disappear again.
At some point in time I managed to complete the rebuild and would have the system up and running for 2 months or so (it's not in production yet I am doing tests and including functionality). lately I had to restart it again and we got in that degraded phase.
My guess is its either the disk's fault, or the PSU (850W, but I have 8 disks attached to it). but I wanted to ask around if there is something else I could check, before I go out and buy a new PSU and disk.
Thank you very much for your help.
