First, remove the Hot Spare using xstm:
Select: Tools > Expert Tool > Run
Select: Utilities > Hot Spare > Delete

The Bind your new lun using xstm:
Select: Tools > Expert Tool > Run
Select: Utilities > Bind LUN

Reuben,

Either set your display (export display=ip_address:0.0

or use the non-graphical interface: mstm.

removing GHS, assuming FC60 alias is fc60

Remove Hot sapre disk X:Y
# ammgr -d fc60
Configure LUN8 (RAID 1)
# amcfg -L A:8 -d -r1 -s 64 fc60

-L A:8 is Lun8 on A controller (-L B:8 would be B controller)
-s is the segment size, here I've used 64k (4, 8, 16, 32, 64 are allowed)
-r1 is raid 1
X:Y is the disk ID of GHS & x:y is the disk ID of free disk

Regards

Tim

# amcfg -L A:8 -d 5:3,4:2 -r1 -s 64 fc60

I guess commands should be armmgr and armcfg.

$ man armmgr
No manual entry for armmgr.
$ man armcfg
No manual entry for armcfg.

Instead of using xstm you can try mstm.
Remember when creating LUNs to bind disks located in different SC10 disk enclosures. In this case if total enclosure will go down LUNs will still be alive

Remove Hot sapre disk 5:3
# ammgr -d 5:3 fc60
Configure LUN8 (RAID 1)
# amcfg -L A:8 -d 5:3,4:2 -r 1 -s 16 fc60
Your segment size on the other disks is 16k, so I modified it.

I've also noticed EVERYTHING runs through controller A, you might want to alternate your LUNs over A & B. To do this simply vgreduce every other disk & immidiately vgextend it back in, this is simply a matter of balance.
