I have a Perc 5/i in a Dell Precision 590. The controller DOES have a battery backup, and the controller reports that its status is healthy. There are five 1TB SATA drives connected to the controller. My original config looked like this:
- VD0: RAID5
- PD0
- PD1
- PD2
- VD1: RAID1
- PD5
- PD7
Fairly simple setup. Last week we had a power failure and I was notified that both VDs were degraded. So I investigated. The configuration has changed. Here is the new configuration:
- VD0: RAID5
- PD0
- PD1
- PD5
- VD1: RAID5
- PD0
- PD1
- PD5
This makes no sense. How is this even possible!?
Note: The PD Mgmt screen says that Discs 0, 1, and 5 are online and 2 and 7 are "foreign" (what does that even mean???).
Ever weirder, much to my surprise: The VDs both seem to be completely functional and all of my data is intact and my system runs fine. I'm at a loss for words.
I have the data backed up, so it won't be The Worst Day Ever if I lose it and have to restore. But I'd really rather not have that happen. If this had been a normal drive failure, I'd know what to do. But this state is so fubarred I'm afraid to even touch it. Help?
Here are some "screenshots" (for lack of a better word) that hopefully will add some context / additional information if needed.
