To obtain information about migration processing, you can
request a standard storage-pool report.
About this task
Four fields on the standard storage-pool
report provide you with information about the migration process.
They include:
- Pct Migr
- Specifies the percentage of data in each storage pool that can
be migrated. This value is used to determine when to start or stop
migration.
For random-access and sequential-access disk storage
pools, this value represents the amount of disk space occupied by
backed-up, archived, or space-managed files that can be migrated to
another storage pool. The calculation for random-access disk storage
pools excludes cached data, but includes files on volumes that are
varied offline.
For sequential-access tape storage pools, this
value is the percentage of the total volumes in the storage pool that
actually contain data at the moment. For example, assume that a storage
pool has four explicitly defined volumes, and a maximum scratch value
of six volumes. If only two volumes actually contain data at the moment,
then Pct Migr is 20%.
This field is blank for copy storage
pools and active-data pools.
- High Mig Pct
- Specifies when the server can begin migrating data from this storage
pool. Migration can begin when the percentage of data that can be migrated
reaches this threshold. (This field is blank for copy storage pools
and active-data pools.)
- Low Mig Pct
- Specifies when the server can stop migrating data from this storage
pool. Migration can end when the percentage of data that can be migrated
falls below this threshold. (This field is blank for copy storage
pools and active-data pools.)
- Next Storage Pool
- Specifies
the primary storage pool destination to which data is migrated. (This
field is blank for copy storage pools and active-data pools.)
