For
remote_copy_sync
tasks, there are three phases:
•
Phase 1 (startup): sync request has been received and synchronization is scheduled to start.
•
Phase 2: performing the resynchronization.
•
Phase 3: copying has completed and cleanup (such as deleting snapshots and setting state
values) is taking place.
In the
showtask
output, the
Step
column indicates the completed and total volume size, in MBs,
using the format
<completed_size>/<total_size>
.
For remote copy synchronizations, the finish time in the
showrcopy
output for the resynchronization
task may not match the
LastSync
column in the
showrcopy
command output for the system holding
the primary volumes. This is because the times are taken at different points in the process. The task
time is set by the task subsystem when it is marked as
completed
, whereas the
LastSync
time
is set when remote copy completes the sync. These two times should be similar, but may differ by
up to a few seconds.
You cannot use the
canceltask
command to cancel a remote copy synchronization task.
For details about volume synchronizations and remote copy commands, see the HP 3PAR Remote
Copy Software User’s Guide.
NOTE:
The
remote_copy_sync
task type requires the HP 3PAR Remote Copy Software license.
The
tunevv
CLI command requires the HP 3PAR Dynamic Optimization Software license.
scheduled_task
The
scheduled_task
task type is used to track system operations initiated by the System Scheduler
commands. See
Table 12 (page 137)
for a complete list of the System Scheduler commands. See
Table 13 (page 137)
for a complete list of the CLI commands that can be initiated with the System
Scheduler commands. The
scheduled_task
task type has only one phase and one step.
snapspace_accounting
The
snapspace_accounting
task type tracks the progress of the snapshot space usage
accounting process and runs the
updatesnapspace
command. The snapshot space usage
displayed by
showvv-s
is not necessarily the current usage. You have to issue the
showvv -hist
command to display the last time
updatesnapspace
was run on the virtual volumes. The
TimeCalculated
column shows the last time the usage was calculated. The
updatesnapspace
command causes the system to begin 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.
The
updatesnapspace
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.
startao
When a
startao
command is scheduled, the user-defined schedule name appears in the list of
schedules. The
startao
command syntax and operation are described in the HP 3PAR Command
Line Interface Reference, “Start Commands” section. For more information about Adaptive
Optimization concepts and usage, see
“Adaptive Optimization” (page 140)
