1) Yes you can alter the existing DATACLAS to support extended addressability
2) Existing datasets will not be affected until recreated, and even then,
*maybe*
An extract from my extended dataclas:
Data Set Name Type . . . . . : EXTENDED
If Extended . . . . . . . . : PREFERRED
Extended Addressability . . : YES
Record Access Bias . . . . : USER
It would be far safer in my opinion to have you STGADMIN's create a new
dataclas and specify that dataclas when defining the file.
ACS routines to support Extended dataclas are at you discretion.

Subject: Re: ZFS - Allocation Failure
Thank you sir. Is it possible to alter the existing Data clas to address the
extended format ? Will there be any impact to the existing Datasets ?
