Indicator Description
LED Indicates that channel interface input/output
(Green) operations are enabled. If the LED is off, the system
is not accepting data.
Indicates DC under voltage, DC over current,
(Red) abnormally high temperature, or an unrecoverable
failure. If your disk array is set up to report messages
to the remote center, your HP service representative is
notified automatically. If the disk array is not set up to
report messages to the remote center, you should
place a service call to HP to have the message
evaluated to determine if any action is required.
LED ON: Indicates that a message has been issued from
(Amber) either cluster. If your disk array is set up to report
messages to the remote center, your HP service
representative is notified automatically. If your disk
array is not set up to report messages to the remote
center, you should place a service call to HP to have
the message evaluated to determine if any action is
required.
Blinking: Indicates the internal service processor has
failed. The disk array will continue to operate
normally. You should place a service call to HP to
ensure notification. Service processor failures might
not be reported automatically to the remote center.
Switch Used to unfence the fenced drive path and to release
Write Inhibit. There is a blocked path somewhere
between a host and a disk drive. By restarting the
subsystem, a soft reset will be performed to try to
recover. If system restart does not unblock the path,
an HP service representative will be notified.
