28 Recovery from hardware failure
Recovery from failure of a DCO volume
the entries for the snap objects, vol1_snp and SNAP-vol1_snp, that point to vol1
and SNAP-vol1 respectively.
You can use such output to deduce the name of a volume’s DCO (in this example,
vol1_dco), or you can use the following
vxprint command to display the name of a
volume’s DCO:
# vxprint [-g diskgroup] -F%dco_name volume
You can use the vxprint command to check if the badlog flag is set for the DCO of a
volume as shown here:
# vxprint [-g diskgroup] -F%badlog dco_name
This command returns the value on if the badlog flag is set. For the example output, the
command would take this form:
# vxprint -g mydg -F%badlog vol1_dco
on
Use the following command to verify the version number of the DCO:
# vxprint [-g diskgroup] -F%version dco_name
This returns a value of 0 or 20. For the example output, the command would take this
form:
# vxprint -g mydg -F%version vol1_dco
The DCO version number determines the recovery procedure that you should use:
