I have a disk in a RAID-5 array (1 of 4 disks) that is showing as failed on our PowerEdge 2800. We have a PERC 4e/Di RAID Controller that shows Physical Disks 0, 2 and 3 all online but 1 doesn't appear (this is the one blinking amber at me).
I assume the disk has failed and as a result I need to replace it. But I'm looking for a few instructions as to how this should be done.
Is it simple a case of powering down the server, removing the disc and then inserting the new one and all is well again or do I need to go into the RAID via Open Manage and tell it to rebuild that disk?
Any advice appreciated as always.
