Changing Plex Attributes
CAUTION Change plex attributes with extreme care, and only if necessary.
The vxedit command changes the attributes of plexes and other volume
Manager objects. To change plex attributes, use the following command:
# vxedit set field= value ... plex_name ...
The comment field and the putil and tutil fields are used by Volume
Manager commands after plex creation.The putil field attributes are
maintained on reboot; tutil fields are temporary and are not retained
on reboot.
Both the putil and tutil fields have three functions and are numbered
according to those functions. These fields can be modified as needed.
Volume Manager uses the utility fields marked putil0 and tutil0.
Other VERITAS products use fields marked putil1 and tutil1. Fields
marked putil2 and tutil2 are user fields. Table 6-1, The putil[n] and
tutil[n] Fields, lists the functions of the putil and tutil fields.
Refer to the following command:
# vxedit set comment=”my plex” tutil2=”u” user=”admin” \
