Backup, replace drives with larger ones, configure RAID, restore from backup.
I have a PE R210 w/PERC H200.  The RAID config is 2 HD in RAID 1.  I was looking at options for expanding storage capacity.  Someone please correct me if I'm wrong, but I've read that it's not possible to extend the VD by upgrading each hd one at a time to rebuild the RAID VD, then extending it to occupy unused HD space.  There are no other HD slots available on the R210, so what options do I have if I want to retain the current VD but increase storage space on the server?
R210 with PERC H200 increase HD options
