Cause and Action
This is not a fault.
This indicates that the disk array unit is in normal operation after turning
on.
This indicates the disk array unit power-on sequence has not been
completed.
It takes several minutes for the POWER LED to turn on after turning on
the unit.
If LEDs do not turn on within 10 minutes, check the following:
 Confirm that power is being supplied to the unit.
 Confirm that INPUT GOOD LED on the back of the unit is on. If it is
off, check the cable connection and power source.
This indicates that the disk array unit or connected disk enclosure
requires maintenance. Since there are two or more maintenance
requests at the same time, check all of the following:
 Confirm that power is being supplied to both PS0 and PS1 in the disk
array unit or connected disk enclosure.
To ensure that power is being supplied, confirm that POWER LEDs of
the disk array unit and disk enclosure are on.
 When SERVICE LED of the connected disk enclosure is on, refer to
the description of "SERVICE LED is on".
 When the last operation is maintenance, processing such as disk
recovery may take time. Ask the maintenance personnel for the
estimated time of completion. If the disk is not recovered beyond the
estimated time, ask the maintenance personnel to investigate.
