GroupStartIU
Command:
GroupStartIU SnapshotGroup
Description:
This command is used to start the Image Update process on a specified group of snapshot relationships. Perform the Image Update process on a snapshot relationship if you want to update the destination volume images with the latest changes to the source volumes.
Arguments:
SnapshotGroup: A valid snapshot group name.
Return Value:
0: success.
-1: failure (see the Comments section below).
Error Codes:
DCSPIT_ERROR_PENDING: The process was started and has not yet completed.
DCSPIT_ERROR_DEVICE_BUSY: A virtual volume involved in this operation is not ready to accept this command. Reissue the command. (If the virtual volume is a DP mirror and you are on the read-only side of the DP mirror, you must re-issue the command on the storage server that contains the read-write side of the DP mirror.)
DCSPIT_ERROR_REQUEST_ABORTED: The Snapshot abort Image Update CLI/API operation was issued, and the process was stopped.
Comments:
If you want to monitor the progress of the process, you can use the GroupGetStatus command to verify that the process is still active. To discover why the process may have aborted, use the GetLastErrors command.
The destination volumes of the snapshot relationships must not accessed while this process is taking place.
If you had a Complete Image, a complete physical copy of source volume data on the destination volumes, prior to performing the Image Update process on the snapshot relationships, and you want to re-establish the Complete Image, you must perform the GroupStartCI command again, once the Image Update process has completed.
