To update space management settings for your file system from the command line, use the dsmmigfs update command.
On GPFS™ file systems, you can use the GPFS policy engine to monitor space thresholds and search for migration candidates.
For information about configuring GPFS integration with the Tivoli® Storage Manager for Space Management client, see the Tivoli field guide TSM for Space Management for UNIX-GPFS Integration Part I: Policy-driven Threshold Migration at https://www.ibm.com/support/docview.wss?uid=swg27018848.
If you do not use the GPFS policy engine to control migration, specify the settings with the dsmmigfs update command.
For example, to change the high threshold to 80 and the low threshold to 70 for the /home file system, issue the command: dsmmigfs upd -ht=80 -l=70 /home .
