If this value is passed for one of the managed file systems, recalls are preferred again after the file system usage drops by 5%. For example, if a threshold of 93% is selected, recalls are preferred again when the file system usage is at or below 88%. 

## 11.1.2 IBM Spectrum Scale commands 

If no threshold value is specified, the current value is shown, for example: 

ltfsee threshold 22 

Use these commands to manage GPFS file systems that you use with your IBM Spectrum Archive EE system. 

## The mmapplypolicy command 

To manage migration and replication of the data to and from IBM Spectrum Scale storage pools, run the GPFS mmapplypolicy  command. It can also be used to delete files from IBM Spectrum Scale. 

The node on which the command is run must have the GPFS mounted. The node must be able to run remote shell commands on any other node in the IBM Spectrum Scale cluster without the use of a password and without producing any extraneous messages. For more information, see “Requirements for administering a GPFS file system” in GPFS: 

Administration and Programming Reference , SA23-2221. GPFS documentation is available at IBM Knowledge Center.

For more information about the mmapplypolicy  command and about GPFS or IBM Spectrum Scale, see your GPFS or IBM Spectrum Scale documentation. 

## The mmgetstate command 

To display the state of the IBM Spectrum Scale daemon on one or more nodes, run the GPFS mmgetstate  command. 

The node on which the command is run must have the GPFS mounted. The node must be able to run remote shell commands on any other node in the IBM Spectrum Scale cluster without the use of a password and without producing any extraneous messages. For more information, see “Requirements for administering a GPFS file system” in GPFS: 

Administration and Programming Reference, SA23-2221, and the websites that are referenced in “The mmapplypolicy command” on page 324. 

The GPFS mmgetstate -a  command displays the nodes where GPFS is active. 

## 11.1.3 Tivoli Storage Manager for Space Management commands 

There is a subset of Tivoli Storage Manager for Space Management commands that you can use to configure and administer space management for the file systems that are used with your IBM Spectrum Archive EE system.
