I have a Dell Power Edge 2800 running a RAID1/RAID5.
Perc 4e/Di embedded.
The RAID 5 is using 3 drives.
Initially all 3 drives showed degraded (predictive failure).
I forced the first drive off line and replaced it with a new replacement (3 brand new matching drives).
After the rebuild finished the state of that drive still showed Degraded.
I then forced the second drive off line and replaced it with one of the new replacements.
After the rebuild the first drive now shows a state of online (no longer degraded).
However the second drive (the one I just installed and rebuilt) still shows degraded.
I said OK this must be some kind of "Rescan" issue that resolves when the controller sees new hardware.
So I went ahead and replaced the third (last disk) with the last new replacement disk.
After the rebuild the second disk now shows a state of Online (no longer degraded).
However the third disk (the one I just replaced) is showing a state of Degraded.
So I requested a global rescan, when that finished the second and third drive now show a state of Degraded.
Notes: Both "Degraded" drive states show up as noncritical.
The virtual disk status is (and has been the whole time) online (nondegraded).
I've rebooted several times with no help.
I don't like having this critical server displaying these types of messages and I'm very concerned by them.
I do a nightly backup (that works most nights).
Can anyone explain this behavior and help me correct it?
