[gpfsug-discuss] mass recall from on-prem COS using a policy

Hi all,

I need to recall from on-prem COS a folder with subfolders and files, approximately 4600 files making up 656G.
We have a policy that runs every 30 mins, and I added this line to it:

RULE 'migrate_iac-workspace_Chem-labs' MIGRATE FROM POOl 'migrate' TO POOL 'data' WHERE PATH_NAME LIKE '/gpfs/nhmfsa/bulk/share/workspace/iac-workspace/Chem_Labs/%'

Migrate is an external pool
RULE EXTERNAL POOL 'migrate' EXEC '/usr/lpp/mmfs/bin/mmcloudgateway files' OPTS '-F' ESCAPE '% -'

And data is the default placement pool
RULE 'Placement' SET POOL 'data'

When it runs it identifies matching files:
Rule#     Hit_Cnt               KB_Hit                 Chosen                KB_Chosen         KB_Ill    Rule
13          4846                     2491152              4846                     2491152              7056      RULE      'migrate_iac-workspace_Chem-labs'       MIGRATE  FROM      POOL  'migrate'  TO  POOL  'data'     WHERE(.)

I can't find what 'KB_ Ill' means but nothing is migrating.

Migrations in other policies work, but this is a 'recall' policy.

It suggests it should be invoked as a recall.

Any ideas?

Kindest regards,
