Steps to Follow
Using "vol verify" command on Sun StorEdge[TM] T3/T3+ Arrays

NOTE: This document describes how to check if the  vol verify   command should be executed.  Vol verify  is a disk scrubbing utility that verifies the integrity of the data on the disks.  This document assumes  you have already determined what drive has failed in step 2 of <Document: 1009745.1>  Troubleshooting T3 Disk Failures To determine if you should use the  vol verify  command  you will need to go through the following steps.  

Troubleshooting Steps:

1. Determine which version of T3 firmware is running by using the  ver  command:

Example:

storage-t3b:/:<13>ver

T3B Release 3.1.6 Thu Feb  3 16:39:28 PST 2005 (10.1.229.133)

Copyright (C) 1997-2003 Sun Microsystems, Inc.

All Rights Reserved.

2. If you are running 3.x or higher verify disk_scrubber is enabled run the command  sys list :

Example:

storage-t3b:/:<2>sys list
controller         : 2.0
blocksize          : 64k
cache              : auto
mirror             : auto
mp_support         : rw
naca               : off
rd_ahead           : off
recon_rate         : med
sys memsize        : 128 MBytes
cache memsize      : 1024 MBytes
enable_volslice    : on
fc_topology        : auto
fc_speed           : 1Gb
disk_scrubber      : on
ondg               : befit

3. If disk_scrubber is not "on" or you running 2.x firmware run the command 'vol verify fix' otherwise return to <Document: 1009745.1>  Troubleshooting T3 Disk Failures

NOTE: Vol verifies runs constanly if disk_scrubber is enabled and there is no need to use the  vol verify  command.

Example:

storage-t3b:/:<4>vol verify v1 fix
WARNING - Volume verification can take a significant amount of time.
Continue   [N]: y
Volume verification in progress...

4.Once  vol verify fix  has completed return to <Document: 1009745.1>   Troubleshooting T3 Disk Failures , step 4.
