The vxedit command changes the attributes of plexes and other Volume Manager objects. To change plex attributes, use the following command:
# vxedit [-g diskgroup] set attribute=value ... plex
The following example command sets the comment field, and also sets tutil2 to indicate that the subdisk is in use:
# vxedit -g mydg set comment="plex comment" tutil2="u" vol01-02
To prevent a particular plex from being associated with a volume, set the putil0 field to a non-null string, as shown in the following command:
# vxedit -g mydg set putil0="DO-NOT-USE" vol01-02
