Hello,
VOL=(,,,20) - A non-specific request for up to 20 volumes to be allocated for a DSN.
This parameter is always used when defining multi-volume DASD datasets in my shop, but from what I can find on the net, this is only supposed to be used for multi-volume TAPE DSN's. I was told that this PARM was changed to include DASD DSN's as well. Can anyone verify this for me because I am not sure if I am coding things correctly?
If anyone can supply me with more detail on the VOL=(,,,20) Parm then feel free!
Thanks |

Hi,
1. One of the JOBs at my shop uses
| Code: |
//ONEWFILE DD DSN=&NODE..GQUSM145.SALEFILE.NEW,
// DISP=(NEW,CATLG,DELETE),
// RECFM=FB,
// LRECL=85,
// BLKSIZE=0,
// UNIT=&DUNIT,
// &VOLC,
// DATACLAS=HUGE |
where
| Code: |
DUNIT=DUNIT='SYSDA',
& VOLC='VOL=(,,,149)', |
So you can go ahead with your code, test it once & check if system throughs some errors.
2. You cannot override the volume count for an existing system-managed DASD data set (but you can specify a volume count when you create a new system-managed DASD data set).
Hope this helps. |

Take a look at the IDCAMS ALTER command, because you can add extra volumes to a DASD dataset, as well as remove them. |
