Removing a RAID-5 log

To identify the plex of the RAID-5 log, use the following command:

# vxprint [-g diskgroup] -ht volume

where volume is the name of the RAID-5 volume. For a RAID-5 log, the output lists a plex with a STATE field entry of LOG.

To dissociate and remove a RAID-5 log and any associated subdisks from an existing volume, use the following command:

# vxplex [-g diskgroup] -o rm dis plex

For example, to dissociate and remove the log plex volraid-02 from volraid in the disk group, mydg, use the following command:

# vxplex -g mydg -o rm dis volraid-02

You can also remove a RAID-5 log with the vxassist command, as follows:

# vxassist [-g diskgroup] remove log volume [nlog=n]

By default, the vxassist command removes one log. Use the optional attribute nlog=n to specify the number of logs that are to remain after the operation completes.


  Note   When removing the log leaves the volume with less than two valid logs, a warning is printed and the operation is not allowed to continue. The operation may be forced by additionally specifying the -f option to vxplex or vxassist.
