# HSM window

Contents

After Hierarchical Storage Management (HSM) has been configured for a file system, this HSM Copytool chart displays a moving time-line of waiting copytool requests, current copytool operations, and the number of idle copytool workers. For information about setting up HSM for a file system, see Configuring and using Hierarchical Storage Management.

On this window, you can:

• | Select to display copytool operations for all file systems (default), or one you select.

• | Mouse over the graph to learn the specific values at a given point in time.

• | Use Change Duration to change the time period for the range of data displayed on the HSM Copytool chart. chart. The chart begins at a start time set and ends now. You can set this to select Minutes, Hours, Days or Weeks, up to four weeks back in time and ending now. The most recent data displayed on the right. The number of data points will vary, based primarily on the duration.

• | Click Actions > Disable to pause the HSM coordinator for this file system (pause HSM activities). New requests will be scheduled and HSM activities will resume after the HSM coordinator is enabled. To enable again, click Actions > Enable.

• | Click Actions > Shutdown to stop the HSM coordinator for this file system. No new requests will be scheduled.

If a copytool has been added but never configured or started, then click Actions to show the following menu:

• | Start - Configure and Start this copytool to begin processing HSM requests.

• | Remove - Deconfigure and remove this copytool from the manager database. It will no longer appear on this HSM window. This is best way to remove a copytool.

• | Configure - Configure this copytool on the worker. Do not start the copytool. Status will show as Configured.

• | Force Remove - Remove this copytool from the manager database without deconfiguring this copytool on the worker node. It will no longer appear on this HSM window. This is NOT the best way to remove a copytool, because a later attempt to add this copytool back will fail unless it is manually reconfigured. Only consider using Force Remove if Remove has failed.
