Working with external storage pools
With external storage pools you can migrate files to storage pools managed by an external application such as IBM Spectrum Protect™.
The following topics describe how to work with external storage pools:
- Defining external pools
When you define external pools, follow these rules. - User-provided program for managing external pools
After you define an external storage pool, subsequent migration or deletion rules might refer to that pool as a source or target storage pool. - File list format
Each call to the external pool script specifies the pathname for a temporary file that contains a list of files to be operated on. - Record format
The format of the records in each file list file can be expressed as shown in the following example. - Migrate and recall with external pools
After you define an external storage pool, subsequent migration or deletion rules might refer to that pool as a source or target storage pool. - Pre-migrating files with external storage pools
Pre-migration is a standard technique of Hierarchical Storage Management (HSM) systems such as IBM Spectrum Protect. - Purging files from external storage pools
Files that have been migrated to an external storage pool continue to have their file name and attributes stored in GPFS; only the file data has been migrated. Files that have been migrated or pre-migrated to an external storage pool may be deleted from the GPFS internal storage pool and from the external storage pool with the policy language using a DELETE rule.
