Changing the active policy

When you prepare a file with the new or changed policy rules, then issue the mmchpolicy command.

The mmchpolicy command activates the following sequence of events:
  1. The policy file is read into memory, and the information is passed to the current file system manager node.
  2. The policy rules are validated by the file system manager.
  3. If the policy file contains incorrect rules, no updates are made and an error is returned.
  4. If no errors are detected, the new policy rules are installed in an internal file.

Policy changes take effect immediately on all nodes that have the affected file system mounted. For nodes that do not have the file system mounted, policy changes take effect upon the next mount of the file system.
