Re: Change Raid Settings

[DrFranken <midrange@xxxxxxxxxxxx>]

So the set with some drives with no stripe (the model -070 guys have no 
stripe) is easy.  Go into SST work with Disk Units and Work with Disk 
configuration and work with removing disk units. Pick one and remove 
from ASP.  In a couple hours or less it will "Go Away".  Once that 
happens pick the drive also and remove it from RAID. (I THINK This step 
will require DST but brain fuzzy on SCSI) Now Start Hot Spare. Done.

The set with all drives striped will require you to end RAID and that's 
more 'risky' so you'll want a full SAVE 21 first. Then Pick a drive, 
remove from ASP, when it's gone then do END RAID on that set (see the 
risky part?) Now tell it to start RAID with Hot Spare. Done.
