To verify that a resynchronization took place, check the tasks by using the showtask command.
For information about using the showtask command, see

“Viewing Synchronization Task

Information” (page 96)

Tracking Asynchronous Periodic Volume Groups

For asynchronous periodic mode volume groups, the startrcopygroup command starts
synchronization only the first time the command is issued for a volume group. Subsequent instances
of the command do not initiate resynchronization of asynchronous periodic mode volume groups.

HP 3PAR Remote Copy does not create a new task for each resynchronization of an asynchronous
periodic volume group. Instead, HP 3PAR Remote Copy keeps the initial synchronization task active
for as long as the group is in the Started state, and updates task details when resynchronizations
occur.

Viewing Synchronization Task Information

To see a list of the tasks that were active on a system within the last 24 hours, use the following
command:

# showtask

The following showtask command output shows that four active tasks are in progress, one for
each primary volume group being synchronized. All four volume groups are in the process of initial
synchronization.

Id Type Name Status Phase Step -------StartTime------ ------FinishTime-------

71 remote_copy_sync vv.1 active 2/3 256/1024 Wed Mar 30 14:33:10 PST 2005 -

72 remote_copy_sync vv.0 active 2/3 256/1024 Wed Mar 30 14:33:10 PST 2005 -

73 remote_copy_sync vv.3 active 2/3 0/1024 Wed Mar 30 14:33:19 PST 2005 -

74 remote_copy_sync vv.2 active 2/3 0/1024 Wed Mar 30 14:33:19 PST 2005

where:

Id

—Task ID for the displayed task.

Type

—Task type. For remote-copy synchronizations, the task type is remote_copy_sync.

For more information about task types, see the HP 3PAR Command Line Interface Administrator’s
Guide
.

Name

—Name of the volume being synchronized.

Status

—Task state. Possible statuses are:

done

—The task has completed successfully.

active

—The task is still in process.

cancelled

—The task was cancelled by you, the user.

failed

—The task failed to complete for a reason other than user cancellation.

Phase

—For active tasks, indicates the number of completed phases and the total number of

phases, in the following format:

<#completed_phase>/<#total_phases>

Each task is composed of a system-determined number of phases.
