Information-error LED
When the information-error LED is lit, a noncritical event has occurred.
Check the light path diagnostics panel and the error log. Light path diagnostics are
described in more detail in the light path maintenance analysis procedure (MAP).
Location LED
The SAN Volume Controller does not use the location LED.
Hard disk drive activity LED
When it is lit, the green hard disk drive activity LED indicates that the hard disk
drive is in use.
Hard disk drive activity is shown on the hard disk drive activity LED. For the
SAN Volume Controller 2145-8F2, hard disk drive activity is also shown on the
hard disk drive itself.
Power control button
The power control button turns on or turns off the main power to the SAN Volume
Controller.
To turn on the power, press and release the power control 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 control button. For more
information about how to turn off the SAN Volume Controller node, see “MAP
5350: Powering off a SAN Volume Controller node” in the
IBM System Storage SAN
Volume Controller Troubleshooting Guide .
Attention: When the node is operational and you press and immediately release
the power control button, the SAN Volume Controller indicates on its front panel
that it is turning off and writes its control data to its internal disk. This can take up
to five minutes. If you press the power control 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 control button for more than two seconds.
Note: The 2145 UPS-1U does not turn off when the SAN Volume Controller is shut
down from the power control button.
Power LED
The green power LED indicates the power status of the SAN Volume Controller.
The power LED has the following properties:
