You can use the Mega Raid Utility for all of this VS using the RAID BIOS. Then once its done remove old drive, replace with new, and add to the RAID 1. Hopefully it can resync before the other drive goes bad. Otherwise get a new drive and add it to the better of the two drives in the RAID 1. Hopefully it can rebuild to the new drive! As for backups when you do you do? Do you use a 3rd party program or windows backup and if windows backup is it a FULL windows backup? Like OS and everything? If so i would just restore from there. Yea get those drives replaced asap! Take the least back of the two, toss it back in the RAID card, add a new drive to it and add it to the RAID 1.
If you don't use that make sure you clone the drive, and then boot off that cloned drive to make sure everything is there. Do a Backup before you do this and make sure its a 100% FULL BACKUP! This way if everything is lost for what ever reason you have a full backup to recovery the ENTIRE system from. Now first and foremost.DO NOT DO ANYTHING UNTIL YOU DO A FULL BACKUP OF THE ENTIRE SYSTEM! If you have Windows Backup up and running great. You can use the two software programs to check to see if its rebuilding or if you need to manually start the rebuild. doing it this way you shouldn't have to do anything if everything is setup correctly. It should see that you're running off the current drive and then sync that drive to the added one.
Now if you do it though software you can just boot off the updated drive only, then after its up and running plug in the other drive. You can use OpenManage or MegaRaid to assign the Hard drive to the RAID (This is a bit easier to deal with that the RAID BIOS I always make sure I have both of those installed on all our Dell servers since the Dell PERC Cards are Branded LSI Cards. Then I would take the other drive, and delete all partitions leaving it with out any partitions on it and then plug it back into the SAS Controller and assign it to the RAID 1.Ī few other thing you can do 1) Download LSI Mega Raid Software and install it on the server along with Dell OpenManage if you don't have it already installed. Usually what I do is take the drive that is out dated on data and remove it form the RAID and plug in the one with the lastest files. Probably got a PERC H200 or 310 or something along those lines. Yea dell servers BIOS haven't changed that much over the years on looks.
