Proliant Server HDD Swap out

Posted on 2010-09-22

Last Modified: 2013-11-10

I need advised. Basically I have a Proliant server that has died but I need to get it online ASAP to get a backup of it as the current one is out of date. I have another Proliant server (slightly different spec) I wondered if I can swap over the disks (Currently its a RAID 5) and power up the server to back it up.

unless there is another way? apart from paying to get the disks recovered.

Many thanks,

HP RAID setups usually store RAID info both on the controller and on the hard drive.  It might be possible to put the drive in another server but there may be some risks.

HP used to offer free phone support even if the parts themselves are out of warranty.

There is more than one disk, it was 5 with a RAID 5, so it would be more than one...

I would not recommend moving the RAID 5 set onto another server without calling HP technical support unless that server had a separate array controller.

The array controller and the drives both have RAID set info on them.

You might possibly transplant the RAID controller from your dead server with the drives.  And make sure the drives stay in the same slots and slot order relative to where they came from.

And again, unless they've changed their policy you should be able to call HP for phone support.  I haven't worked with HP Proliant servers in over 3 years though so I'm a little behind.

And if you want to add the drives to an existing or spare RAID card you can run a system utility (it might be called the system erase utility) to wipe the RAID config from the card.  The drives will tell the wiped card what the RAID config was.  This is useful when you lose an array controller.  And I wouldn't trust a service part or used RAID card to have been completely wiped.

OK thanks ill give it a try, so to some up I will call HP first, but I could get the other server erase the RAID controller then put the disks in with the RAID config on and this should rebuild the spare servers config.... am I getting this right? ...... if I could move the RAID controller with the disk to the spare server would that work? obvioudly if the existing controller is ok.

2. Move your drives with the original RAID card to a new server.  Make sure you keep the slot positions and order the same.

*3) If you must move the drives without the original RAID card then either use them with a new one or a used one who's RAID config has been erased.

This process is not all that uncommon.  HP has even allowed a migration path where you can take drives out of your physical server and mount them in one of their low level SANS, like the MSA1000.

Could swap out disks as long as same server. Checked with HP as mentioned.
