Every task is given a unique task identifier. This is a numeric identifier for the task that can be specified to the vxtask
utility to specifically identify a single task. Several VxVM utilities also provide a -t
option to specify an alphanumeric tag of up to 16 characters in length. This allows you to group several tasks by associating them with the same tag.
The vxassist
, vxevac
, vxplex
, vxmirror
, vxrecover
, vxrelayout
, vxresize
, vxsd
, and vxvol
utilities allow you to specify a tag using the -t
option. For example, to execute a vxrecover
command and track all the resulting tasks as a group with the task tag myrecovery
, use the following command:
# vxrecover -g mydg -t myrecovery -b mydg05
Any tasks started by the utilities invoked by vxrecover
also inherit its task ID and task tag, so establishing a parent-child task relationship.
For more information about the utilities that support task tagging, see their respective manual pages.
