Unable to add encryption policies

If the mmchpolicy command fails when you are trying to add encryption policies, perform the following diagnostic steps:

1. Confirm that the gpfs.crypto and gpfs.gskit packages are installed.
2. Confirm that the file system is at GPFS 4.1 or later and the fast external attributes (--fastea) option is enabled.
3. Examine the error messages that are logged in the mmfs.log.latest file, which is located at:/var/adm/ras/mmfs.log.latest.
