Raid 5 - Swapping failed disk is not working with HP Smart Array Controller P600
Posted on 2012-03-26
Disk failed on our server. HP Proliant DL 380 G5.
2 x Logical drives.
Logical Drive 1 (Array A) -
1 x 72GB 1 Port SAS Port 2I Box 1 Bay 1
1 x 72GB 1 Port SAS Port 2I Box 1 Bay 2
Logical Drive 2 (Array B)
1 x 146GB 2 Port SAS Port 1I Box 1 Bay 5
1 x 146GB 1 Port SAS Port 1I Box 1 Bay 6 ( Failed / Problem )
1 x 146GB 1 Port SAS Port 2I Box 1 Bay 3
1 x 146GB 2 Port SAS Port 2I Box 1 Bay 4
Disk flagged as failed in Event Viewer, and in HP Array Controller Utility. (HP ACU)
All other disks working as usual. All users working on the server as normal.
I took out the failed Bay 6 disk, and replaced it with a brand new spare.
I'm expecting to see some kind of acknowledgement from the status lights to suggest to me that a rebuild is taking place, BUT the lights remain the same ( Off, solid Red ).
So reading up on this, this may mean that the new disk is faulty, so I try another brand new one, and the same thing happens.
During this time I am checking and refreshing the HP ACU, and this is still reporting that the disk in Bay 6 has failed.
I can't see anything that tells me a rebuild is taking place, and no way of forcing one.
Ideally. I'd like to see the system recognise the disk and automatically start the rebuild, so that I'm confident everything is OK, but what are anyone elses thoughts ?
We've had a raid controller go down in the past on another server, so in the back of my mind, I'm wondering whether this is the start of an issue with this controller ?
Is it possible for a specific bay to fail at controller level ?
The HP ACU is telling me that no other array configuration/change can take place without resolving this problem.
I understand that with Raid 5, I don't want to be messing with the working disks, but when considering my options, I was wondering whether I could somehow extend the array to say, Bay 7, and take Bay 6 out of the picture at the same time. ( if a bay failure was a possibility).
Like I said, I don't want to take additional risks unnecessarily, It would be nice for a Raid 5 issue to be simple for once? I'm sure they are 99.9% of the time, but .......
Help and advice please.
