I have a Power Vault MD 1000 which includes a RAID 5 array (I inherited it), open manage server administrator reports the structure as RAID 5. Today one of the three disks failed.
I would have expected it to become "Degraded". But I got failed virtual disk. And, on omsa, I only have the options "Delete..." , "Blink" , "Unblink". I googled up and down, left and right and I could not find no page explaining in what circumstances one physical drive causes full virtual drive to fail. All pages said it requires two. Beside those three drives I have a fourth one that is "foreign". Here's what I did so far :
- removed the faulty drive (orange led)
- borrowed a working drive from another machine and inserted it
- System reported both foreign drives, but virtual disk remained "failed".
- I cleaned foreign and both drives become ready (the other two that belong to vdisk are online), again v disk continued failed.
I removed the "new" drive and inserted the old one, I was expecting the old drive to become "failed" as before, but it became "foreign" rather. But the main problem remains, the v drive continues "failed", not degraded. Is there someway to rebuild it? I have backups of most but not of everything, unfortunately.
