No, I only remember that there were two discs with failure warnings. That is why we decided to reboot the enclosure.
That was the wrong action to take. RAID5 and two failed disks is a dangerous combination. RAID5 can only sustain a single disk failure.
Your external enclosure is likely an HP StorageWorks MSA60, rather than the D2600 unit you linked. The main point is the same, though. You should have corrected the disk failures rather than reboot the enclosure/system. Having a logical drive in failed status means that the array has failed and the data is possibly gone.
My recommendation to you is to power the server down and also physically remove power to the MSA60 enclosure (remove the cables, don't just press the power button). Leave the systems off for 5-10 minutes.
Power the enclosure back on. Give it 60-90 seconds to spin up the disks. Follow by powering on the server.
Pay close attention to the POST messages, specifically the initialization of the Smart Array P800 controller. You MAY be prompted to enable a previously failed logical drive.
Logical drive(s) disabled due to possible data loss.
Select "F1" to continue with logical drive(s) disabled
Select "F2" to accept data loss and to re-enable logical drive(s)
RESUME = "F1" OR "F2" KEY
If prompted with this, you will want to press
F2 to re-enable the logical drive.
See what happens once the system has completed booting. If this is successful, you'll want to make sure the disks are healthy, then possibly update firmware on the server, controllers, disks and MSA units, since there have been bugs that trigger false drive failures and other undesirable behavior on this equipment.
