Turning off the SAN Volume Controller node
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 in the IBM System Storage SAN Volume Controller 2145 Troubleshooting Guide.
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.
