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 HSM systems automatically delete a file from the external storage manager whenever the online file is deleted. If that is how your HSM system functions, your script will only have to delete the online file.
