Usage notes

When using the POOLACC command, consider the following:

1. The pool authorities, which are ADMN, TAPE, READ, and NONE, are hierarchical; that is, the authorization priority is (from top to bottom):
   1. ADMN. Required for pool management functions.
   2. TAPE. Required for tape management functions and READ/WRITE access to tapes in the pool.
   3. READ. Required to read tapes in the pool.
   4. NONE

   If more than one of these permissions is issued for the same ID, the last permission processed will be in effect. For example, if TAPE access is granted to an ID that has ADMN authority, the result is that the ADMN authority will be removed and TAPE authority will be granted.

2. If the system is configured so that no authorization is required to access the system free pool, the system free pool permissions are recorded, but not used.
3. If the system is configured so that no authorization is required to define private pools, the system pool permissions are recorded, but not used.
4. If an ID is not defined to the system, the command fails and no permissions are changed for any other IDs targeted by the command.
5. The owner of a private pool does not require FREE permission to use that pool name as a FREEPOOL designation in a POOLDEF command.
6. A system administrator does not have permission to mount volumes in a private pool by default. System administrators, however, can move volumes to or from a private pool without additional authorization.
