Power button
The power button turns main power on or off for the SAN Volume Controller .
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 process can take up to 5 minutes. If
you press the power button but do not release it, the node turns off immediately without the
SAN Volume Controller
control data that is 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 2 seconds.
