Mail can be sent to users other than root.
See “Modifying the behavior of hot-relocation” on page 422.
You can determine which disk is causing the failures in the above example message
by using the following command:
# vxstat -g mydg -s -ff home-02 src-02
The -s option asks for information about individual subdisks, and the -ff option
displays the number of failed read and write operations. The following output
display is typical:
FAILED
TYP NAME READS WRITES
sd mydg01-04 0 0
sd mydg01-06 0 0
sd mydg02-03 1 0
sd mydg02-04 1 0
This example shows failures on reading from subdisks mydg02-03 and mydg02-04
of disk mydg02.
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 must investigate the problem and attempt
to recover the plexes. 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 using the following command:
# vxrecover -b -g mydg home src
This starts recovery of the failed plexes in the background (the command prompt
reappears before the operation completes). If an error message appears later, or
if the plexes become detached again and there are no obvious cabling failures,
replace the disk.
See “Removing and replacing disks” on page 130.
Complete disk failure mail messages
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, you can receive mail
as shown in this example display:
To: root
Subject: Volume Manager failures on host teal
