I have a Dell PowerEdge r510, with 5 HDDs in a RAID6 configuration. I'd like to add a 6th disk (and, in the future, more) to grow the hardware RAID configuration. I have a logical volume, in which the current disks are all physical volumes. I have MegaRAID command tools, but cannot see a way to expand the RAID volume without the storage manager software (which I don't have): http://techpubs.sgi.com/library/manuals/0000/860-0488-001/pdf/860-0488-001.pdf. Can anyone tell me if there is a way to expand the hardware raid volume with MegaRAID or otherwise online (and without reboot if possible)?
Thanks!
