3.2.2 Powering Off
If you need to power off the entire system, such as when switch or RAID system requires
firmware updates, adding a RAID system or client computer, power off in the reverse
order of Powering On. Before turning off SWF16, turn off the all the client computers first.
Wait for complete client computers to shut down and then the SWF16, then the ExaSAN
storage systems.
During RAID initiation or disk drive rebuilding, you can turn off the client computers only
and leave the SWF16 and storages powered on.
