abort

Causes the specified task to cease operation. In most cases, the operations "back out" as if an I/O error occurred, reversing what has been done so far to the largest extent possible.

list

Lists tasks running on the system in one-line summaries. The -l option prints tasks in long format. The -h option prints tasks hierarchically, with child tasks following the parent tasks. By default, all tasks running on the system are printed. If a taskid argument is supplied, the output is limited to those tasks whose taskid or task tag match taskid. The remaining arguments are used to filter tasks and limit the tasks actually listed.

monitor

Prints information continuously about a task or group of tasks as task information changes. This allows you to track the progression of tasks. Specifying -l causes a long listing to be printed. By default, short 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.

pause

Puts a running task in the paused state, causing it to suspend operation.

resume

Causes a paused task to continue operation.

set

Changes modifiable parameters of a task. 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 slow is specified, this introduces a delay between such operations with a default value for iodelay of 250 milliseconds. The larger the value of iodelay that is specified, the slower is the progress of the task and the fewer system resources that it consumes in a given time. (The slow attribute is also accepted by the vxplex, vxvol and vxrecover commands.)
