The Volume Manager Task Monitor tracks the progress of system recovery
by monitoring task creation, maintenance, and completion. The Task
Monitor allows you to monitor task progress and to modify characteristics
of tasks, such as pausing and recovery rate (for example, to reduce
the impact on system performance). You can also monitor and modify
the progress of the Online Relayout feature.
Task Monitor Options |
 |
Command line option (-t) allows you to specify a task tag for
any task.
You can use the Task Monitor option with the following utilities:
vxplex, vxsd, vxvol, vxrecover, vxreattach, vxresize, vxassist, and vxevac
Task monitor option -t takes the following form:
# utility [-t tasktag] ... |
where:
utility—Volume Manager utilities that support the -t option.
tasktag—Assigns the given task tag to any tasks
created by the utility. All tasks related to this operation are
identified as a group.
For example, to execute a vxrecover command and track all resulting tasks as a group,
specify a task tag to the vxrecover command, as follows:
# vxrecover -t myrecovery -b disk05 |
The vxrecover command creates a task to track all recovery jobs.
To establish the task tag grouping, the vxrecover command specifies the tag to all utilities that
it calls. Additionally, to establish a parent-child task relationship
to any tasks those utilities execute, the vxrecover command passes its own task ID to those utilities.
For more information about the utilities, see their respective
manual pages.
