Table 10-4: Trouble in Disk Enclosure

Cause and Action
This is not a fault.
This indicates that the disk enclosure is in normal operation after turning
on.
This indicates that starting the disk enclosure has not been completed.
The power of the disk enclosure is turned on in conjunction with the
power of the connected disk enclosure or disk array unit.
It takes several minutes until POWER LED of the disk enclosure turns on
after turning on the unit power.
If POWER LED does not turn on within 10 minutes, check the following.
 Check whether INPUT GOOD LED of the disk enclosure power supply
is on, indicating that the power is supplied to the disk enclosure.
 Check cable connection status to confirm whether this disk enclosure
is normally connected to other disk enclosures or the disk array unit.
 Check POWER LED of the disk array unit to confirm whether the
power of the disk array unit was turned on. If this LED is out, check
whether the power source is functioning normally.
This indicates that the disk enclosure is out of order or maintenance has
not been completed.
 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.
