Mirror Hard Drive on Dell

[mswilson16]

Hi All,

I just bought a new dell server (Server 03), and one of the drives failed... I have now got a replacement drive but need to set the drives to be mirrored again.

I had someone come out to disable the alarm that was sounding becuase the mirrored drive was missing, but now I want to mirror the drives again.

I am assuming I need to put the drive in as a slave, then go to the Dell Array Manager and then I am lost.... Any advise will be great...

With most new servers (DELL in my experience also) if you place the replacement drive into the drive bay then the server will automatically rebuild the new disk back into the array as a mirrored drive for you.

You can check its progress using the Dell Array Manager.

will this happen even though we went in a disabled (or deleted not quite sure) the mirror in the disk array manager? If not, what is the manual process to do this?

thanks

From your post it sounds like all that was done was to disable the audable alarm.

There is a chance that the person who disabled the alrm changed the Virtual Disk from a RAID1 (mirror) to a RADI0 (no RAID). In this case it wouldnt automatically rebuild.

If you open up the Dell OpenManage Array Manager

close the quick launch screen if it appears

expand your server name (top right)

expand 'arrays'

Under here you will have something like PERC Subsystem1.Expand it.

find your array controller (probably a PERC controller) and expand it

under here you will have Array Group expand that too

Under here you will see Virtual Disks. If you have just two mirrored drives then there will be only on.

right click and look at the properties of the virtual disk and in here it will tell you its RAID level. If it is RAID0 then it is no longer mirrored.

To change it back to RAID1 right click on the Virtual Disk and select Transform Type from the menu.

Change it back to RAID1

Put in your new disk

right click on the virtual disk again and select add member.

Select you new disk to add it to the mirror set.

It will now rebuild the mirror (will take a lot of time depending on the size of the disk.
