Specify selection criteria for files to pack

To define which files to select for packing, create FilePools policies. The policies you create are applied when the SmartPools background job runs.

1. Create FilePools policies that define the data sets to pack.
   The syntax is:

   isi filepool policies create <policy_name> --enable_packing=true /
   --begin_filter --path=<path_name> --changed-time=<time> --operator=<operator> --end-filter

   where:

   <policy_name>

   Identifies this FilePool policy.

   --enable_packing=true

   Enables packing on the data sets in this policy. See Disable packing for disable options.

   --path=<path_name>

   Identifies a data set.

   --changed-time=<time>

   --operator=<operator>

   These two parameters set the amount of time that must pass since a file was modified before that file is selected for packing. The default amount of time is the global value set by isi packing --min-age. Use this policy-specific --changed-time parameter to increase the amount of time to wait since changes were made to a value greater than the global setting.

   NOTE: The policy-specific --changed-time parameter can not decrease the amount of time to wait before selecting the file for packing to less than the global setting. Any value less than the global --min-age setting is ignored. If you want a setting that is less than the current global default, you must first change the global --min-age parameter in the isi packing command.

   The following example enables packing on the /ifs/data/pacs data set.

   isi filepool policies create pacs --enable_packing=true /
   --begin_filter --path=/ifs/data/pacs  --end-filter

   The following example specifies that a file in /ifs/data/pacs is selected for packing only if 1 week has passed since the file was last modified.

   isi filepool policies create pacs   --enable_packing=true /
   --begin_filter --path=/ifs/data/pacs --changed-time=1W /
   --operator=gt --end-filter

2. Wait for the SmartPools job to run.
   The data sets identified in the FilePools policies are packed by the SmartPools job.
