When instructed to do so, shut down and turn off the SAN Volume Controller node
before you remove and replace parts.
For information about how to turn off the
SAN Volume Controller and retain access to its data, see
MAP 5350: Powering off a SAN Volume Controller node.
Attention: Unless host systems or fibre-channel switches must
be switched off for another reason, do not turn them off when you
are servicing the SAN Volume Controller.
Shut down the SAN Volume Controller before
you remove the power cables. You can connect or disconnect Ethernet
and fibre-channel cables at any time.
