NAME : HCPADABK
DESCRIPTION: Address Space Data Array
DSECT : ADABK
FUNCTION :
Defines a fixed-length array containing data about
address spaces during a live guest relocation
LOCATED BY :
Source system -
Transient area, accessed only within HCPRLLSE
Destination system -
The RLOADRSP field of the RLOBK
CREATED BY :
Source system -
HCPRLLSE during source system eligibility
checking.
Destination system -
HCPRLLDE during initial destination eligibility
checking.
DELETED BY :
Source system -
HCPRLLSE after completing source eligibility
checking.
Destination system -
HCPRLNCT during destination system STMGT cleanup.
REFERENCES :
None.
SERIALIZED :
An ADABK is created on the source system once during
each relocation, and once created is never updated.
It is destroyed by HCPRLLSE (Source system storage
eligibility checking) at the close of the initial set
of eligibility checks.
The ADABK is sent to the destination system where it
is used by one task at a time, either HCPRLLDE
(Destination system storage eligibility checking)
or by HCPRLLCS (Create guest address spaces), neither
of which update the block. On the destination, the
ADABK is released only by HCPRLNCT (Cleanup routine
for LGR Memory Move - Target System).
Any relocation-supported changes to the storage
configuration will be communicated to the destination
system as part of the memory move (for example, a
change in the standby storage amount). Any
unsupported storage configuration changes (such as
using the DEFINE STORAGE command to change the amount
of configured storage) will fail a relocation in
progress.
RELOCATION CONSIDERATIONS : This block is sent from the source to the
destination system.
NOTES :
None.
