The system has issued a QUERY command with the ACTIVE, USER, or REQUEST parameter.

DFSMShsm space management (which includes MIGRATING, MIGRATION PREPROCESSING, FREEVOL PROCESSING and DBA/DBU PROCESSING), backup, recovery, recycle, full volume dump, volume restore, or audit is processing the volume with the volume serial number volser. If DS BACKUP is indicated, the volser is the output tape volume. If SGROUP follows volser, the request was for a BACKVOL specifying storage group sg. If COPY POOL follows volser, the request was for a dump initiated by a FRBACKUP command with copy pool cpname specified.

userid is the user identification of the initiator. The request is the DFSMShsm request number, except for automatic primary space management, automatic backup, automatic dump or internal copy when NONE is indicated. The request number is nonzero only for requests received by DFSMShsm through the DFSMShsm SVC console. The request-number is the number of the request. user and request are both '*' when DS BACKUP is indicated. If the TCBADDRESS subparameter was used with the ACTIVE parameter, the tcbaddress value represents the unique task identifier for the function and can be used with the CANCEL command to end the active task. See the DFSMShsm CANCEL command for usage information.

The tcbaddress value represents the unique task identifier for the function and can be used with the CANCEL command to end the active task. See the DFSMShsm CANCEL command for usage information. 'TCB' is the first tcbaddress to cancel. If the function does not end and a 'TCB2' address is given, the tcbaddress in 'TCB2' can then be used. If the TCB value is ****?***, no TCB was found.

Note: The actual number of migration tasks can be equal to the number of tasks specified on the MAXMIGRATIONTASKS or the MAXINTERVALTASKS and up to twice the specified number of tasks because of DFSMShsm's preprocessing enhancement. This is reflected in the number of ARC0161I messages issued in response to the QUERY ACTIVE and/or QUERY ACTIVE(TCB) commands. With migration subtasking, there will be additional ARC0161I messages per migration volume task, up to the number of subtasks running. MIGRATING, MIGRATION PREPROCESSING, FREEVOL PROCESSING, and DBA/DBU PROCESSING differentiate the type of space management DFSMShsm is performing and these are displayed in the ARC0161I message.

taskname is the task name of movement task. volser1, volser2 and volser3 are the tape volume serial numbers of movement task. address1, address2 and address3 are the device address of the tape volumes.
