You should be aware that if you delete a storage group while a job that uses this group is running, the job might fail with message IGD17201I. To prevent this, consider performing the following:

1. Modify your storage group ACS routine so that it does not assign the storage group to be deleted to any new allocations. Validating your configuration causes message IGD06023I to be received. This message is only a warning. As long as there are no error messages, your configuration is valid.

2. Activate the configuration with the modified storage group ACS routine and allow it to remain active until jobs that used the old ACS routine have completed. This allows executing jobs to complete using the existing storage group definition.

   _______________________________________________________________

3. Delete the storage group from the configuration. Because the storage group no longer exists in the configuration, you do not receive MSGIGD06023I.

4. Activate the configuration from which the storage group has been deleted.
