Re: Removing (unconfigured) disks from RAID-5 array?

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

As Larry pointed out the rules for SCSI and SAS are different since the 
controller cards are completely different.

I think in V6 and up with the right RAID cards you could go into SST and 
set the RAID configuration rules.  From SST, Work with Disk 
Configuration, option 8 work with device parity protection and then 
Option 7 select parity optimization you were able to pick from 1) 
availability, 2) balance, 3) capacity, and 4) performance.  Those 
options changed how the system would stripe the disk units.
