No, because on a recall, the data class ACS routine is not called. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of O'Brien, David W. (NIH/CIT) [C] Sent: Wednesday, January 09, 2013 2:13 PM To: [email protected] Subject: Re: ESDS extent ...
Isn't the assigning of a dataclass upon recall dependent on the coding of the dataclass acs routine rather than HSM? -----Original Message----- From: Don Williams [mailto:[email protected]] Sent: Wednesday, January 09, 2013 2:09 PM To: [email protected] Subject: Re: ESDS extent ... When HSM (or equivalent product) recalls a data set, it has to allocate the space on the primary DASD. That allocation will need data class attributes. In my opinion, the HSM manuals are not clear how or where HSM gets the data class attributes. I believe you, but it would be nice if the HSM manuals clearly stated that the data class attributes of a recalled data set were solely obtained from the migrated copy of data set and not from the current SMS data class. >From the z/OS V1R12.0 DFSMShsm Storage Administration manual: ============================================================================ ============================================= Chapter 54. RECALL command: Recalling a specific migrated data set The RECALL command recalls a migrated data set. If you want, you can specify the volume and type of unit where DFSMShsm is to recall the data set. If you specify the volume and type of unit when recalling an SMS-managed data set, the volume and unit type will be passed to the automatic class selection (ACS) Routines. ACS ultimately determines to which volume the data set is recalled. The FORCENONSMS parameter allows the ability to force recall of an SMS-managed data set to a non-SMS-managed volume. It is not possible to convert a data set that is not extended format to a data set that is extended format during a recall. However, you can convert an extended format data set to a data set that is not extended format during a recall, if you specify the FORCENONSMS optional parameter. ============================================================================ ============================================= Don Williams -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of R.S.

It would be interesting to know if that would work. It is not matter whether DC is called or not (it's not AFAIK). It's matter that even changed DC does not affect existing dataset parameters. It will not affect. Caution: parameters like DVC can be changed dynamically, but actually DVC is some "potential bahavior" not "actual shape" of the physical object. Of course REPRO or EXPORT/IMPORT will change the EA parameter. -- Radoslaw Skorupka Lodz, Poland -- Tre tej wiadomoci moe zawiera informacje prawnie chronione Banku przeznaczone wycznie do uytku subowego adresata.
