Backup, delete IM (Integrated Mirror - RAID 1), replace disks with larger ones, create new IM, restore from backup. You would have other options on a PERC controller, but the SAS 5 is very limited.
Hi, I got a PowerEdge 1900 with a SAS 5/iR Adapter. Currently 2 SATA, 250 GB drives are being used in a RAID1 config. What is the best way to upgrade to 2 500GB drives ? thanks, John
