Programming Interface Information:
The Monitor Records are intended Programming Interfaces that
allow the customer to write programs to obtain services of z/VM.

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.
