Replacement Raid5 drives still show degraded status
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?
Thx,
John

It is likely that 1) your firmware is out of date or 2) your array is damaged. What are your BIOS and PERC firmware versions?

The LED on the second drive is green.
The LED on the third drive is amber/green.
I'll get screen shot and firmware version ASAP.
The LED on the third drive is amber/green.

amber/green means predictive failure
when did it go amber/green? after it finished rebuilding?
