Compaq ProLiant DL380 HDD replacement RAID5

We have Compaq ProLiant DL380 server with RAID configured as RAID5.
Currently there are 4 HDDs of 18.2Gb(7200rpm). The problem is that two of them are showing a red warning sign.
Could you please advise how can I replace them by new ones? Should I power down the server?
One more question is: Is it ok to use HDDs with other than 18Gb size and/or 7200rpm speed but having the same interface (SCSI ULTRA2)?

Regards,
Sergey.

Re: Compaq ProLiant DL380 HDD replacement RAID5

If two of 4 drives failed then the logical drive should be no longer operational.

Or was this a RAID5+Hotspare configuration and maybe the drives didn't fail at the same time ?

Re: Compaq ProLiant DL380 HDD replacement RAID5

hi,

As 2 hdd showing failed
If possible recomnded try to take the backup ( No second thought in that )
Then try to re connect the 1 hdd then check it is trying to rebuild or not or still same problem presist

Or

visit this site
http://h18007.www1.hp.com/support/files/server/us/locate/20_1122.html

Run this utility
Hard Drive Identifier ( to check for faulty HDD )
M&P Patch ( for removing false error )


If this helped u do revert back,

Regards,

Hi Martin.

Yes it is RAID5 + hotswap.
You are right drives gone not at the same time.
And thay are not faulty I hope. They just show red sign on the fromt panel but still operational.

Thanks

Hi Prashant,

We have ordered 2 drives, and awaiting for delivery. Then I will try to remove them one by one with rebuild.

Utility does not find any drives, I expect it is not for our drive type.

Thanks.

The M&P patch will only prevent predictive failures and not actual ones indicated by a solid LED.

With 2 drives showing solid amber and the system still being functional, I would suspect a faulty SCSI backplane on the cage as the drive lights come from there.

Have you checked the cabling for bent pins? Is the optional 2 drive cage installed on this server? Has the ROC firmware been updated?
