Currently, we have a Compaq proliant that is running 3x 18gig SCSI drives in Hardware Raid 5. Weve now exceeded the hard drive space on these drives, and need to decomission them. Weve got 3x 147gig drives to take over, but unsure how to mirror the contents across.
So far, ive tried the following,
Leaving the exsisting raid 5 array in tact, and connecting up the additional 3x147gig drives, then creating a new raid 5 array for these 3 drives. Then I loaded up Symantec Ghost, and cloned the contents from the old aray to the new aray.
Then I deleted the old aray from the hardware raid controller, and left the array of the 147gig drives in tact, but the system wouldnt boot from them.
Whats the best way to do this?
