Need help adding raid groups (sasmgr)

HI All,


Would like to request for some assistance on the error I'm getting.


The machine already got an existing raid 1 group. We basically added 2 bnew disk.

What I'm trying to do, is create a new raid group (raid 1) with the new disks.


However, running sasmgr with the add command throws off device busy error. Do I need to create a new raid device?

Do I need to shutdown the system? Would appreciate any clues or help extended. Thanks!
