3-12 Sun StorEdge 5310 NAS Troubleshooting Guide • December 2004
1. Stop I/O activity to all modules.
2. Remove the front cover from the command module, if applicable.
3. Determine the status of each module and its components.
a. Note the status of the lights on the front and the back of each module.
A green light indicates a normal status; an amber light indicates a hardware fault.
b. Open the Array Management Window for the storage array.
c. To view the status of its components, select the appropriate component button
for each module in the Physical View of the Array Management Window.
The status for each component will be either Optimal or Needs Attention.
4. Does each module display green lights only and is the status Optimal on each
module component?
■ Yes - Go to step 6.
■ No - Go to step 5.
Note – If the fault requires you to power off an attached drive module, you may
need to cycle the power on all remaining modules in the storage array. Before you
power off any attached module, contact technical support.
5. Diagnose and correct the fault.
a. To run the Recovery Guru, select the Recovery Guru toolbar button in the Array
Management Window.
b. Complete the recovery procedure.
If the Recovery Guru directs you to replace a failed component, use the individual
lights on the modules to locate the specific failed component. For troubleshooting
procedures, refer to “Troubleshooting and Recovery” on page 3-22.
c. When the recovery procedure is completed, select Recheck in the Recovery
Guru to re-run the Recovery Guru and to ensure that the problem has been
corrected.
d. If the problem persists, contact technical support.
Caution – Potential data corruption. An abrupt power loss to any module in a
storage array can cause data corruption, especially if the power loss occurs when
data is being written to a disk or if the power loss occurs when write back caching is
enabled and data is being downloaded to cache memory. Before turning off power to
the modules, always wait until the Cache Active light turns off and all drive Active
lights stop flashing.
