Adding a RAID-5 log

  Note   You need a full license to use this feature.

Only one RAID-5 plex can exist per RAID-5 volume. Any additional plexes become RAID-5 log plexes, which are used to log information about data and parity being written to the volume. When a RAID-5 volume is created using the vxassist command, a log plex is created for that volume by default.

To add a RAID-5 log to an existing volume, use the following command:

# vxassist [-b] [-g diskgroup] addlog volume [loglen=length]

If specified, the -b option makes adding the new log a background task.

You can specify the log length used when adding the first log to a volume. Any logs that you add subsequently are configured with the same length as the existing log.

For example, to create a log for the RAID-5 volume volraid, in the disk group, mydg, use the following command:

# vxassist -g mydg addlog volraid
