virtual volumes, run the showvv -hist command. The TimeCalculated column shows the
last time the usage was last calculated. The
updatesnapspace command causes the system to
start calculating current snapshot space usage. If one or more virtual volume names or patterns
are specified, only the specified virtual volumes are updated. If no virtual volume names are
specified, all virtual volumes are updated.
This command immediately returns the task ID associated with the updated snapshot space
usage accounting process. The
canceltask command cannot be used to cancel the
snapspace_accounting task type. To wait for completion, use the waittask command.
The
snapspace_accounting task type has only one phase, and the number of steps is equal
to the number of virtual volumes affected by the
updatesnapspace command.
13.3.13 system_task
The system_task task type tracks the housekeeping tasks periodically run by the InServ
storage server. You can display any active housekeeping tasks with the
showtask -all
command. Only the
3parsvc user can run, change, or remove these tasks.
CLI housekeeping tasks and commands:
■ The move_back_chunklet runs the moverelocpd command.
■ The remove_expired_vvs runs the removevv command.
The
system_task task type has only one phase and one step.
13.4 System Scheduler
The System Scheduler allows you to create, modify, and remove schedules for initiating system
operations with long running times. With the System Scheduler commands you can schedule
specific CLI commands to run at regularly scheduled intervals, or to run once at a specified
time.
