Instead of having DASDVOL update access to volumes for IPL(DASD), you can act as a DFSMSdss-authorized storage administrator for the BUILDSA command by specifying the ADMINISTRATOR keyword.

The FACILITY-class profile STGADMIN.ADR.STGADMIN.BUILDSA for the BUILDSA command ADMINISTRATOR keyword lets you build the Stand-Alone Services IPL-able core image without having UPDATE access to the output data sets or UPDATE access to a DASD volume when you create a core image for IPLing from DASD. You must still have access at the data set level for the input data set.

See the ADMINISTRATOR keyword in Explanation of BUILDSA command keywords for more information.
