VERITAS Volume Manager 3.1 Administrator's Guide

Disk Tasks
Detecting Failed Disks
Chapter 4176
# vxstat -s -ff home-02 src-02
A typical output display is as follows:
FAILED
TYP NAME READS WRITES
sd disk01-04 0 0
sd disk01-06 0 0
sd disk02-03 1 0
sd disk02-04 1 0
This display indicates that the failures are on disk02 (and that subdisks
disk02-03 and disk02-04 are affected).
Hot-relocation automatically relocates the affected subdisks and
initiates any necessary recovery procedures. However, if relocation is not
possible or the hot-relocation feature is disabled, you have to investigate
the problem and attempt to recover the plexes. These errors can be
caused by cabling failures, so check the cables connecting your disks to
your system. If there are obvious problems, correct them and recover the
plexes with the following command:
# vxrecover -b home src
This command starts recovery of the failed plexes in the background (the
command returns before the operation is done). If an error message
appears later, or if the plexes become detached again and there are no
obvious cabling failures, replace the disk (see “Replacing a Disk”).
Complete Disk Failure
If a disk fails completely and hot-relocation is enabled, the mail message
lists the disk that failed and all plexes that use the disk. For example,
mail information is sent as shown in the following display:
To: root
Subject: Volume Manager failures on host teal
