Purpose

This document addresses the identification of failed or failing disk drive(s) in the array via various symptoms provided.

Symptoms:

• Performance degraded
• Disk Fault LED lit/on
• Global Fault LED lit/on

Please validate that each troubleshooting step below is true for your environment. The steps will provide instructions or a link to a document, for validating the step and taking corrective action as necessary. The steps are ordered in the most appropriate sequence to isolate the issue and identify the proper resolution. Please do not skip a step.

Troubleshooting Steps

1. Validate that you can telnet into your 6120/T3.

• If you cannot log into your array via telnet, <Document: 1012660.1> Sun Storage 3000 and T3 Arrays: Troubleshooting Serial and Network Management Port Connections
• Otherwise continue to Step 2.

2. Validate disk drive status against a detailed FRU status report by executing the command fru stat.

example:

•   If status is ready-enabled, go to Step 5.
•   If status is substituted, go to Step 7.
•   If status is ready-disabled,  go to Step 3.
•   If status is fault-disabled, go to Step 4.
•   If there are more than one drive in a state other than ready-enabled, go to Step 5.

3. Validate local and/or global hot spare presence and state.

Verify the presence and status of a hotspare by:
a) executing the command vol list to confirm the existence of local hotspare under the column "standby"
b) executing the command global_standby list to confirm the existence of global hotspare

• If a hot spare is present, go to Step 4, to verify if a reconstruction is in progress.
• If there are no hot spares configured, go to Step 8.

4.  Verify the presence of an ongoing reconstruction by:

Executing the command proc list to confirm the existence of a process vol recon

• If there is no reconstruction process, AND the drive is ready-disabled, go to Step 8.
• If there is no reconstruction process, AND the drive is fault-substituted, go to Step 7.
• If a reconstruction is ongoing, allow it to complete before preceding, and re-evaluate the drive status in Step 2.
• If there is no ongoing reconstruction and the drive isn't in a fault-substituted state, go to Step 8.

5.  Check the status of the volume associated to the drive by executing the command vol stat.

• If the volume is "mounted", but more than one drive has a non-zero status, go to Step 8.
• If volume is "unmounted", you have sustained a drive failure beyond the capabilities of your RAID level for the volume.
• Otherwise continue to Step 6.

6.  Validate LED existence against disk drive in ready-enabled state.

• If there is an amber fault LED or any other LED lit for the disk drive, go to Step 8.
• If there is no LED's lit.  You have verified that the disk drive is healthy. 

7.  You have validated that a drive has failed in the array, and requires replacement. 

Collect the the following information and contact Oracle Support for a drive replacement:

The output of:
fru stat
vol stat
proc list
fru list

OR

Collect the array data from a Solaris host by running:  /opt/SUNWexplo/explorer -w !default,t3extended

8.  At this point, if you have validated that each troubleshooting step above is true for your environment, and the issue still exists, further troubleshooting is required. 

Please open a Service Request with Oracle Support.

Please include:

• Statement of Symptoms you see that pertain to the disk drive
• Collect the array data from a Solaris host by running:  /opt/SUNWexplo/explorer -w !default,t3extended
