set
The set operation is used to change modifiable parameters of a task.
Currently, there is only one modifiable parameter for tasks: the slow
attribute, which represents a throttle on the task progress. The larger
the slow value, the slower the progress of the task and the fewer system
resources it consumes in a given time. (The slow attribute is the same
attribute that many commands, such as vxplex(1M), vxvol(1M) and
vxrecover(1M) accept on command lines.)
Output There are two output formats printed by the vxtask command:
a short, one-line summary format per task, and a long task listing. The
short listing provides the most used task information for quick perusal.
The long output format prints all available information for a task,
spanning multiple lines. If more than one task is printed, the output for
different tasks is separated by a single blank line. Each line in the long
output format contains a title for the line, followed by a colon (:), followed
by the information.
Examples To list all tasks currently running on the system, use the
following command:
# vxtask list
The vxtask list command produces the following output:
TASKID PTID TYPE/STATE PCT PROGRESS
162 RDWRBACK/R 01.10% 0/1048576/11520 VOLSTART
mirrvol-L01
To print tasks hierarchically, with child tasks following the parent tasks,
us the -h option, as follows:
# vxtask -h list
Use of the -h option produces the following output:
TASKID PTID TYPE/STATE PCT PROGRESS
167 ATCOPY/R 06.79% 0/1048576/71232 PLXATT mirrvol
mirrvol-02
To trace all tasks in the diskgroup foodg that are currently paused, as
well as any tasks with the tag sysstart, use the following command:
# vxtask -G foodg -p -i sysstart list
