Can I hot-swap disks in a Dell Compellent StorageCenter SAN with larger ones (one at a time, allowing them to rebuild between each change) and end up with more total available storage?
Little more detail
We have an old Dell Compellent StorageCenter SAN with 12x ST3600057SS (600GB) hard drives. Total available storage space is ~6TB. I want to increase the total storage significantly, replacing each 600GB drive with at least a 2TB drive.
The Compellent SAN has 3x logical volumes, all on the "High Priority (Tier 1)" storage profile (RAID 10 Active, RAID 5 Replay). 11 Disks are managed and 1 is spare (single redundant).
I know that with RAID 1/5/6, you can replace disks one by one and, once all are the new size, you'll end up with more usable space. However, I'm not sure if the same is true for RAID 10 or if there's anything special I have to do on the SAN.
Sadly I inherited this system with little to no documentation, so I'm kinda flying blind. I don't have any manuals for the SAN nor any documentation from the previous sysadmin.
Other possibly relevant info:
We have two model CT-SC040 controllers running version 6.6.5. RAID 5 stripe width is 9 Wide (90% efficient). RAID 6 stripe width is 10 wide (80% efficient).
