 NAME       : LGRVPXBK
 DESCRIPTION: Relocation mapping for HCPVPXBK
 DSECT      : $VPXBK
 FUNCTION   : LGRVPXBK describes those fields of the VPXBK that
              will be migrated to the destination system during
              guest relocation.
 LOCATED BY : This is a mapping of the RDODATA area within the
              RDOBK during guest relocation.
 CREATED BY : HCPRLFXF - VPXBK Formatter for LGR
 DELETED BY : HCPRLDRL - Release storage associated with an RDP
 RELOCATION CONSIDERATIONS : This control block is used during live guest
              relocation.  It is used to relocate a control block
              defined in a corresponding HCP COPY file.  Any
              fields or bits defined in HCPVPXBK which are
              required on the destination system must be defined
              here, and code must be added to migrate the field
              or bit during a relocation.

Version is independent of the CP level and need only be changed when this DSECT is changed. The convention is to increment by 1. 0000 0 Signed 2 $VPX_HDRL Header length (in bytes) 0002 2 Signed 2 $VPX_BITL Length of mapped bits (in bytes) 0004 4 Signed 4 * Reserved for future use 00000008 $VPX_HDLN *-$VPXBK Length of header (bytes) Bit map: Contains the VPXBK flags that are subject to relocation. These bits are defined sequentially, regardless of how they are defined in HCPVPXBK. This yields a consistent mapping that ensures compatibility when a guest is relocated between systems at differing service levels. Names in the comments column indicate the control block byte which contains the flag. This name is subject to change if the flag definition changes. ====> NEVER change bits which already exist here. ====> NEVER change the order of bits in this section. ====> ALWAYS add new bits at the end of this section, together with new flag bytes as required. 0008 8 Signed 2 $VPX_BITS (0) Bit map area 0008 8 Bitstring 1 $VPX0 1... .... $VPXTT0V X'80' $VPXTT0V VPXFLAG1 .1.. .... $VPXTT1V X'40' $VPXTT1V VPXFLAG1 ..1. .... $VPXTT2V X'20' $VPXTT2V VPXFLAG1 ...1 .... $VPXTT3V X'10' $VPXTT3V VPXFLAG1 .... 1... $VPXBTS X'08' $VPXBTS VPXFLAG1 .... .1.. $VPX4WCGM X'04' $VPX4WCGM VPXFLAG1 .... ..1. $VPXBLKDC X'02' $VPXBLKDC VPXFLAG1 .... ...1 $VPXALLDC X'01' $VPXALLDC VPXFLAG1 0009 9 Bitstring 1 $VPX1 1... .... $VPXCLPRS X'80' $VPXCLPRS VPXFLAG2 .1.. .... $VPXBIGBF X'40' $VPXBIGBF VPXFLAG2 ..1. .... $VPXOVPRT X'20' $VPXOVPRT VPXFLAG2 ...1 .... $VPXNORML X'10' $VPXNORML VPXFLAG2 .... 1... $VPXLFCB X'08' $VPXLFCB VPXFLAG2 .... .1.. $VPXB4WCG X'04' $VPXB4WCG VPXBFTR1 .... ..1. $VPXBBTS X'02' $VPXBBTS VPXBFTR1 .... ...1 $VPXBBTS3 X'01' $VPXBBTS3 VPXBPLNI 00000002 $VPX_BLEN *-$VPX_BITS Length of bit map area Data: Contains all HCPVPXBK data that is subject to relocation, except for flag bits, which are handled separately.
