Migrating spool volumes
A JES2 spool migration moves an existing JES2 spool volume (an
extent or data set) to a new spool volume, or merges an existing volume
with another existing spool volume. Migrating a spool volume to a
new spool volume is called a move migration.
Migrating a spool volume to an existing spool volume is called a merge
migration. Both types of spool migration enhance JES2
spool configuration by providing the following functionality:
- Increasing or reducing the total number of spool volumes.
- Increasing or reducing the size of spool volumes.
- Extending volumes that have insufficient space to map all tracks.
- Removing spool volumes without altering any spool pointers (MTTRs or MQTRs).
- Copying of data from one spool volume to another while address spaces are actively reading and writing data to the spool volumes.
- Merging of volumes and track group map onto another spool volume.
- Creating a new spool volume.
Note: Before attempting a spool migration, you must review the $MSPL - Migrate spool volumes command usage in its entirety.
