You can use the EDGSPLCS utility to issue supported commands to OAM for system-managed volumes. DFSMSrmm builds the input commands for this utility automatically during EDGUTIL VERIFY(SMSTAPE) processing and EDGHSKP EXPROC processing when you request them.

You can run multiple copies of EDGSPLCS. Using different parameters, EDGSPLCS can be processing in parallel for multiple libraries or multiple drives within a library, but this utility does not ensure that each parameter is different from any other currently running.

You need ALTER authority to the relevant volume catalog in order to use the EDGSPLCS utility to update the TCDB. For example, if you use just one volume catalog and use the default volume catalog prefix, you need ALTER access to SYS1.VOLCAT.VGENERAL

When the INDD control statement includes a ‘Q’ verify request, EDGSPLCS exploits a SYSTEMs level ENQ using qname SYSZRMM rname EDGSPLCS.volser to ensure that a volume in the list can only be processed by one instance of EDGSPLCS. Each instance goes down the list looking for volumes that match the execution parameters and selects the first volume that matches the criteria, and when the Q verify request is specified, issues an ENQ and if it cannot obtain the ENQ, moves to the next volume in the list. If an ENQ is obtained, it verifies that the volume is still in private status and issues CBRXLCS CUA (change use attribute to move the volume to scratch), then finally DEQs, and moves to the next volume in the list.
