Changing Subdisk Attributes
Caution Change subdisk attributes with extreme care.
The vxedit command changesattributes ofsubdisks and other VxVM objects. To change
subdisk attributes, use the following command:
# vxedit set attribute=value ... subdisk ...
Subdisk fields that can be changed using the vxedit command include:
◆ name
◆ putiln
◆ tutiln
◆ len
◆ comment
The putiln field attributes are maintained on reboot; tutiln fields are temporary and
are not retained on reboot. VxVM sets the putil0 and tutil0 utility fields. Other
VERITASproducts,such asthe VERITAS Enterprise Administrator(VEA),set the putil1
and tutil1 fields. The putil2 and tutil2 are available for you to use for site-specific
purposes. The length field, len, can only be changed if the subdisk is dissociated.
For example, to change the comment field of a subdisk named disk02-01, use the
following command:
# vxedit set comment=“subdisk comment” disk02-01
To prevent a particular subdisk from being associated with a plex, set the putil0 field to
a non-null string, as shown in the following command:
# vxedit set putil0=”DO-NOT-USE” disk02-01
See the vxedit(1M) manual page for more information about using the vxedit
command to change the attribute fields of VxVM objects.
