To turn on the power, press and release the power button. You must have a pointed device, such as a pen, to press the button.
To turn off the power, press and release the power button. For more information about how to turn off the SAN Volume Controller node, see MAP 5350: Powering off a SAN Volume Controller node.
Attention: When the node is operational and
you press and immediately release the power button, the SAN Volume Controller writes
its control data to its internal disk and then turns off. This
can take up to five minutes. If you press the power button but do
not release it, the node turns off immediately without the SAN Volume Controller control
data being written to disk. Service actions are then required to make
the SAN Volume Controller operational
again. Therefore, during a power-off operation, do not press and hold
the power button for more than two seconds.
