Help. my AJ736A drives are dropping like flies
Hi Everyone:
All I did was move an MSA2212fc dual controller fiber channel raid shelf with 12, AJ736A, 15k rpm, 300 Gb,
SAS, 3 1/4" enterprise hard drives from one 42U rack to another. I also moved one BL680c G5 server from
one c3000 blade enclosure to another in the same rack as the MSA. Then, I moved the AJ820A SAN switch
and plugged everything in and booted. Only other change was I switched from RAID 5 to RAID 6. The moves
were uneventful. Nothing was bumped or dropped.
I created one large virtual drive and carved it up into 3 equal volumes. Before the move things were fine.
Things were fine for a week or so after the move. Now I'm getting orange LED lights on a few of the hard
drives. It started out with 2 bad drives. I replaced them.
Thinking it might be firmware/drivers, I upgraded the MSA2212fc, the AJ820A SAN switch and the P700M SAS
mezzanine HBA in the blade server to current and searched to see if there was a firmware update for the hard
drives. Didn't find any updates for the drives.
Things were quiet again, but when I came in Monday there was another drive with an orange LED on. On
Tuesday there was another. When I logged into the RAID controller it appears the 2 drives no longer exist. Of
course we have no hardware support and the drives are only warrantied for 3 years. Right now, they're nearly
5 years old.
I've been searching around and this situation isn't discussed anywhere. No mention of the meaning of orange
LEDs on these drives. Can they be recovered with a low level reformat? "New" replacement drives, if you can
fine them, cost between $400 and $500 each. It's killing us. Oh, by the way, the operating system is Windows
2008 R2 Enterprise at SP1
Any ideas?
