For those of you who are planning on installing the z/VM 5.4 z196 APARs, you may be interested in this information.
If your installation had migrated from a earlier release of z/VM (perhaps 5.1.0 or 5.2.0), there is a good possibility that you will run into the same issue that I did when attempting SERVICE ALL for the APAR maintenance envelope file. It seems that a macro file "IRAQVS MACRO" was not erased during the migration procedure. The presence of this macro causes the following errors as shown below. In order to rectify this situation, IBM recommends that you erase the macro from the MNT493 minidisk prior to running SERVICE. If you have already encountered this error, then follow the IBM recommendation above and rerun SERVICE. I hope this is helpful and it saves you the time it took for me to glean this information from IBM. As well, IBM has committed to providing this work-around in a PSP bucket.
