Rebuilding RAID

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

It's been a while and I can't seem to find a manual or any steps that 
describes the sequence I need to follow and it has been too long since I last 
worked with RAID controllers.

Unfortunately we got a couple of Dell servers (PowerEdge 1850). One drive from 
the backup system was used to rebuild a "live" system. Now the backup machine 
needs to be rebuilt from the drive used on the live system. It uses PERC/CERC 
BIOS utility U821 from 2004.

The steps were: the original drive 0 remained in the backup system and drive 1 
was used to rebuild the "live" system.

Then they upgraded the live system and then used a new drive to replace the 
backup drive. This leaves the original backup drive 0 out of date.

My question now is which steps do I take to rebuild the backup system from 
drive 1 and thus make drive 0 a copy of drive 1.
