Why would our RAID Drive say its being rebuilt

We have a HP server and we restarted the server after installing software.  Why would it say its rebuilding a drive?  My worry is that we have a underlying problem and i want to know how we can prevent this sort of message occurring.  Your view on the error log below would be appreciated.  Thanks


RIS event log says logical drive OK but here’s the eventview of the drive (taken HP RAID utility) :

Event 3 indicates a failed drive. Typically when you build a RAID array you allocate a hot standby drive. When a physical drive fails, the controller will automatically swap in the hot standby, and the array would enter a rebuild status until the new drive has been updated, and becomes a fully functioning member of the array. If you check that status of the array now it should be normal/optimal.

You should have the failed drive replaced, and add the replacement to the hot spare pool.
noxcho

Agreed. It reported the drive as failed and suggested replacing it.

Thanks for your quick responce.  We havent swapped any drives before/during/after the error.  All we have performed is a reboot.  Why would the drive rebuild onto the same drive it failed on? Is this something i should be worrying about?

I need to reboot the machine and i dont want it to not restart again saying it has a issue with RAID.

It should not have any issues as RAID reconfigures itself. This is the purpose of RAID - redundancy. Simply replace the failed drive which RAID controller considers to be bad.

sorry i don't think I put my point across clearly enough.  The drive which it said failed is the same drive that is in the computer now and it is being reported ok.  Could it be that the disk is about to fail? Should i ask HP to replace it.

I suppose it could be an intermittent problem. You should contact HP and provide the error report, then let them advise you if it should be replaced. I would think so.

Is the status still rebuilding? Did you really have a hot standby configured.

Thanks for your quick replys.  Not standby, we have only have 4 drives and have RAID 1+0 so no swap drives.

Thats what I thought but all drives are reporting OK,weird...I'm on with HP now
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

HP says under warranty they wont replace the HD because the utility is reported as being ok.  The trigger that caused the RAID to rebuild is because the controller lost connection to the hard drive.  They couldn't say if this was a software issue or a hardware issue but when I restarted the server, they recommended shutting it down and unplug the drive and reseat the drive in question (bay 3).

Thanks for your help guys!
