 NAME       : HCPCUIBK
 DESCRIPTION: CONTROL UNIT INFORMATION BLOCK
 DSECT      : CUIBK
 FUNCTION   : THE CONTROL UNIT INFORMATION BLOCK IS USED TO MANAGE
              DASD CONTROL UNIT INFORMATION.
 LOCATED BY : THE LIST OF CUIBKS IS ANCHORED IN SYSCUIPT
              CUINXTCU  FIELD OF CUIBK  - FORWARD CUIBK POINTER
              RDEVCUI   FIELD OF RDEV   - POINTER TO CUIBK ASSOCIATED
              WITH RDEV
 CREATED BY : CUIBK'S ARE CREATED DYNAMICALLY BY DEVICE INITIALIZATION
              PROCESSING.
 DELETED BY : CUIBK's are deleted by HCPZDRDV during RDEV delete
              processing and by HCPZRPPP during post-processing
              for the RDEVICE statement or SET RDEVICE command.
 SERIALIZED : Addition and Deletion of a CUIBK from the CUIBK chain
              that hangs off SYSCUIPT in the System Common Area is
              serialized by obtaining the SYSCUILK in exclusive
              mode.  Code that runs the SYSCUIPT CUIBK chain in an
              attempt to locate a specific CUIBK should obtain the
              SYSCUILK in shared mode to ensure the integrity of
              the chain.  Serialization of fields in the CUIBK not
              related to the SYSCUIPT chain is handled either by
              running on the Master Processor or as described in
              the line comments below.
 RELOCATION CONSIDERATIONS : None

Multiple summary unit checks could occur for one failover condition if recovery does not finish within the CU's MIH window. We do not want to do recovery multiple times. 0126 294 Bitstring 1 CUISUMUC Summary UC recovery in progress flag The CUIPVOPR byte indicates the PAV mode that this control unit is currently operating in (No PAV, Basic PAV, or HyperPAV). NOTES : The PAV operating mode might be undeterminable for a CU that does not have HyperPAV capabilities. For example, a 2105 CU with Basic PAV capabilities with no PAV Alias devices defined cannot be distinguished from a 2105 CU with NO PAV capabilities. 0127 295 Bitstring 1 CUIPVOPR CU PAV Operating Status Flag 00000001 CUINPVOP X'01' CUINPVOP CU is operating in No PAV mode 00000002 CUIPAVOP X'02' CUIPAVOP CU is operating in Basic PAV mode 00000003 CUIHYPOP X'03' CUIHYPOP CU is operating in HyperPAV mode 000000FF CUIUNDET X'FF' CUIUNDET CU is either running in Basic PAV mode with no aliases currently defined or it is running in No PAV mode (this setting is only for CU's that don't have HyperPAV capabilities) The CUIPVALW byte indicates the highest level of PAV devices allowed for this control unit (No PAV, Basic PAV, or HyperPAV) by CP irregardless of the hardware capabilities of the control unit. CP will always allow the CU to operate in the highest level of PAV mode (HyperPAV) UNLESS the user has indicated what is allowed for this control unit via the CU config file statement or the SET CU command. 0128 296 Bitstring 1 CUIPVALW CU PAV Allowed Indicator 00000001 CUINPVAL X'01' CUINPVAL CU allowed to operate in NOPAV mode 00000002 CUIPAVAL X'02' CUIPAVAL CU allowed to operate in PAV mode 00000003 CUIHYPAL X'03' CUIHYPAL CU allowed to operate in HyperPAV mode The CUIHPVHW byte indicates the PAV capability that is currently installed in the hardware for a control unit that has the potential to use HyperPAV devices when all the required microcode and LICs are installed. 0129 297 Bitstring 1 CUIHPVHW HyperPAV CU Current HW Capabilities 00000000 CUINOTHW X'00' CUINOTHW CU not a HyperPAV capable controller 00000001 CUINPVHW X'01' CUINPVHW HyperPAV CU with NO PAV capabilites 00000002 CUIPAVHW X'02' CUIPAVHW HyperPAV CU with Basic PAV capabilities 00000003 CUIHYPHW X'03' CUIHYPHW HyperPAV CU with HyperPAV capabilities 012A 298 Bitstring 2 CUINUM CU Number 012C 300 Bitstring 1 CUILSS Logical Subsystem ID 012D 301 Bitstring 1 CUICSFLG Flags (serialized by CS) 1... ....
