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 /. 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 updatesnapspacecommand 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.
