program aboutMSS volume mounts and demounts. The Ry register contains
a subfunction code. The valid subfunction codes and their meanings are:• X'OO' - The virtual machine issuing the DIAGNOSE instruction 1S running OS/VS with MSS support and the DMKMSS program for KSS communication. The Rx register contains the device address of the
virtual machine'sMSS communicator virtual device. • X'04' - The virtual machine is ready to process an KSS request. The MSSCOM block representing the request should be placed at the virtual
machine address indicated by the Rx register.• X'08' - An MSS request represented by the MSSCOM block located at the
virtual machine address indicated by the Rx register has been
accepted by theMSC. • X'OC' - An MSS request represented by the MSSCOM block located at the
virtual machine address indicated by the Rx register has been
rejected by theMSC. • X'10' - The DMKMSS program will no longer be available to process MSS requests. I • X'14' - The DMKMSS program has created a list of all VUAs associated I with this processor (cpuid) and requests CP to build its shared and , non-shared SDG tables from that list.
