NAME       : HCPRDEV
 DESCRIPTION: REAL DEVICE CONTROL BLOCK
 DSECT      : RDEV
 FUNCTION   : THE REAL DEVICE BLOCK IS USED TO MANAGE THE REAL
              DEVICE.
 LOCATED BY : HCPRIOIX is the anchor field for the RDEV radix tree
              structure for devices in the default subchannel set.
              HCPRIOIA is the anchor field for the RDEV radix tree
              structure for devices in the alternate subchannel set.
 RELOCATION CONSIDERATIONS : None

 CREATED BY : Real device RDEVs are created in HCPRIO by the
              sysgen process.
              Real device RDEVs are created during SET RDEVICE
              command, machine check CRW processing, or system
              initialization.
              RDEVs are created for logical or SNA devices.
              HCPIID   - Create a real device RDEV
              HCPLSOCR - Create a logical device RDEV
              HCPSRD   - Create a real device RDEV

              HCPZCO   - Create a real device RDEV
              HCPZRP   - Create a real device RDEV
 DELETED BY : Real device RDEVs created in HCPRIO by the sysgen
              process are static and are never deleted.
              Real device RDEVs created during SET RDEVICE
              command, machine check CRW processing, or system
              initialization may be deleted, but only early in
              system initialization before anybody can start
              using them.
              RDEVs created for logical or SNA device are dynamic
              and are deleted when no longer required.
