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.

RULE 'DelFromExt' DELETE WHERE ...

If the file has been migrated or pre-migrated, this would result in the external pool script being invoked as follows:

/usr/hsm/bin/hsmControl PURGE /tmp/filelist -server=hsm-manager.nyc.com

The script should delete a file from both the online file system and the external storage manager. However, most IBM Storage Protect systems automatically delete a file from the external storage manager whenever the online file is deleted. If that is how your IBM Storage Protect system functions, your script will only have to delete the online file.
