Veritas Volume Manager 5.0.1 Administrator's Guide, HP-UX 11i v3, First Edition, November 2009

Prints information continuously about a task or group of tasks as task
information changes. This lets you track task progress. Specifying -l
prints a long listing. By default, one-line listings are printed. In
addition to printing task information when a task state changes, output
is also generated when the task completes. When this occurs, the state
of the task is printed as EXITED.
monitor
Pauses a running task, causing it to suspend operation.pause
Causes a paused task to continue operation.resume
Changes a task's modifiable parameters. Currently, there is only one
modifiable parameter, slow[=iodelay] , which can be used to
reduce the impact that copy operations have on system performance.
If you specify slow, this introduces a delay between such operations
with a default value for iodelay of 250 milliseconds. The larger
iodelay value you specify, the slower the task progresses and the
fewer system resources that it consumes in a given time. (The vxplex,
vxvol and vxrecover commands also accept the slow attribute.)

Using the vxtask command
To list all tasks running on the system, use the following command:
# vxtask list
To print tasks hierarchically, with child tasks following the parent tasks, specify
the -h option, as follows:
# vxtask -h list
To trace all paused tasks in the disk group mydg, as well as any tasks with the tag
sysstart, use the following command:
# vxtask -g mydg -p -I sysstart list
To list all paused tasks, use the vxtask -p list command. To continue execution
(the task may be specified by its ID or by its tag), use vxtask resume :
# vxtask -p list
# vxtask resume 167
To monitor all tasks with the tag myoperation, use the following command:
# vxtask monitor myoperation
To cause all tasks tagged with recovall to exit, use the following command:
