8.1 Troubleshooting Tips
If you suspect the occurrence of a fault during the use of the disk array unit, check the status based on
the tables below. If a symptom which is not described in the tables at all or the specified
countermeasures cannot recover the proper operation, contact your maintenance service representative.
The POWER LED (green) does not light if the power switch is turned on.
Cause Countermeasures
The power cord is not connected. After setting the power switch to OFF, plug the cord
in.
The AC power (100 VAC) is not supplied. Check whether 100 VAC ±10% (50/60 Hz) is
supplied.
The LINKUP LED (green) of the controller on the array controller connected with the FC cable,
LINKUP LED (green) of the adapter in the disk enclosure, or the LOOP STATUS LED (green) of
the host bus adapter connected with the FC cable does not light.
Cause Countermeasures
The FC cable is not connected correctly. Insert the connector of the FC cable until a click is
heard.
See Chapter 5 "Connection of Disk Array Unit".
The length of the FC cable exceeds the
rating value. See Chapter 5 "Connection of Disk Array Unit".
The setting of the host bus adapter or that
of the FC-AL switch is not correct. Provide the proper setting referring to the User's
Guides of the host bus adapter, host unit, and those
of added peripherals.
The used host bus adapter is unavailable
for the disk array unit. Use the host bus adapter available for the disk array
unit. Contact your sales representative if unknown.
The FAULT LEDs (orange) on both adapters of the disk enclosure blink.
Cause Countermeasures
The ENC ID switch on the adapter is set
incorrectly. After setting the power switch to OFF, set the ENC
ID switches on the left and right adapters to be the
same. See Section 5.2 (4) " Setting of switches ".
