Use this command to:
- Convert the pool data structures for each subsystem from pool expansion
(PXP) format to 32-way loosely coupled pool support format
- Return the pool data structures for each subsystem from 32-way loosely
coupled pool support format back to pool expansion (PXP) format
- Display the migration state of each processor in the complex.
Requirements and Restrictions
- You can enter this command only from a processor where the pool format
provided by 32-way loosely coupled pool support is installed and
active.
- You can enter this command only in 1052 state or higher.
Format
- CONVERT
- converts the pool data structures for the current subsystem from PXP
format to 32-way loosely coupled pool support format. When pool
conversion is completed, all pool data structures on DASD are in 32-way
loosely coupled pool support format.
Notes:
- If your complex is loosely coupled, you must ensure that the pool data
structures in main processor storage on each processor in the complex are
current before specifying the CONVERT parameter. Do this by entering
the ZDFPC command on each active processor in the complex.
- All processors in the complex must be currently running from an image
containing 32-way loosely coupled pool support before you convert the pool
data structures. To ensure that all active processors are using 32-way
loosely coupled pool support, enter the ZPMIG command with the STATUS
parameter specified from each active processor. If message PMIG0011I is
returned, the processor is using 32-way loosely coupled pool support.
If any other message is returned, the processor is not using 32-way loosely
coupled pool support. You must re-IPL the processor using an image
containing 32-way loosely coupled pool support before you can specify the
CONVERT parameter.
- You need to enter the command with the CONVERT parameter specified once
for each subsystem in the loosely coupled complex. The command can be
entered from any active processor in the complex. After processing is
successfully completed, all pool data structures that reside in processor
storage and on DASD for the subsystem are in 32-way loosely coupled pool
support format.
- FALLBACK
- changes the pool data structures on DASD for each subsystem from 32-way
loosely coupled pool support format back to PXP format.
- STATUS
- displays the migration state for each processor in the complex. The
migration state can be MIGRATED, UNMIGRATED, or INACTIVE.
