Deactivating space management
To deactivate space management on a single file system, use the dsmmigfs command with the -deactivate parameter. To deactivate space management on all space-managed file systems, use the dsmmigfs command with the -globaldeactivate parameter. Deactivate space management before you or your IBM Storage® Protect administrator perform system maintenance to temporarily prevent migration, recall, or reconciliation processes from occurring. When you reactivate space management on your file systems, all space management services resume.
About this task
Note:
- When you deactivate space management for a file system, the file system state becomes deactivated. Any migration, recall, or reconciliation process that currently is in progress completes before deactivation.
- You can access only resident and premigrated files on a deactivated file system.
- If your administrator exports migrated files from one server and imports them to another, update the dsm.sys file. The client node must contact the new server for space management services. The administrator can use a lock node command to prevent the client node from migrating or recalling files while importing and exporting to another server.
