I want to remove a DAE on my Cx500. I have no Raid Groups bound to any disks on the DAE (I have in the past for testing purposes, but nothing is there now).
I understand that I can turn off my entire SAN, unplug the DAE, then power it back on. I'd rather not do this.
I believe I can...
Power down/unplug DAE (this will make my CLARiiON scream at me with faults until I fix it, but I don't think it will interrupt any I/O)
Reboot SPA, wait for it to come back up
Reboot SPB, wait for it to come back up
The DAE should be removed from NaviSphere.
Does anyone know if this will work? Or if I need to reboot both SPs at the same time?
