     DSECT NAME - IODHPC
     FUNCTION - This record indicates a HyperPAV pool creation
     LOCATED BY -
               Through the Monitor Control Area
     REFERENCED CONTROL BLOCKS -

     NAME - MRIODHPC
     DESCRIPTIVE NAME - Monitor Event Record
                        Domain 6 - I/O Domain
                        Record 29 - HyperPAV Pool creation
     DESCRIPTION - Indicates the creation of a HyperPAV pool
     NOTES:
         The HyperPAV Pool Token is the Subsystem ID (SSID) of the
         logical control unit that all of the devices in the pool are
         associated.  The SSID is a unique value that distinguishes
         it from all other control units in a configuration.
         This value can be obtained from a Q DASD DETAILS command
         executed against one of the device's on the control unit.
         The HyperPAV Pool number is a value that indicates which
         devices (bases/aliases) can be used together in a HyperPAV
         environment.  This value is generated by CP using the SSID
         to ensure that it is unique value in the system.  This value
         can be obtained from a Q PAV command executed against one
         of the devices in the pool.
