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