Changing Subdisk Attributes
CAUTION Change subdisk attributes with extreme care.
The vxedit command changes attributes of subdisks 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 VERITAS products, such as the 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.
