When I catlg a data set at volume TSO0002, it displayed the message below
| Code: |
| VOLUME TSO0002 VTOC IS FULL |
I must delete some data set then I can catlg it .
How can I delete or extend the VTOC ?
the VTOC for TSO0002 now is below
| Code: |
Volume . : TSO002
Command ===>
Unit . . : 3390
Volume Data VTOC Data Free Space Tracks Cyls
Tracks . : 50,085 Tracks . : 30 Size . . : 28,793 1,900

Hi,
You can use any file utility to find the datasets which exists on the volume TSO0002. Then you can delete unwanted datasets from that volume. |

This would actually be a job to be performed by the storage management group responsible for DASD volumes.
Unless you ARE storage management DO NOT try to do this. |

| The storage management team needs to offload all of the datasets and specify the VTOC size while reformatting the DASD. |

| If you have ICKDSF Release 17 or later you can extend the VTOC without the need to offload any datasets. This feature has been available for at least 5 years |

On the point raised by nevilh above, from past experience you may have to move some datasets as the VTOC will not extend unless it can do so contiguously. However, this may have changed since the last time that I had to do this.
Again, depending on which software products that you have installed at your site there may be other ways to do this, FDR/CPK is a great tool for this.
But as mentioned previously, if you ain't storage, then don't try this at home. |

Do you have sample JCL for this, I might need to do this RSN... |

The JCL should look something like this
// EXEC PGM=ICKDSF
//DD1 DD DISP=SHR,UNIT=3390,VOL=SER=xxxxxx
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
REFORMAT DDNAME(DD1) VERIFY(xxxxxx) EXTVTOC(30) EXTINDEX(15)
IF you cannot extend the VTOC (data allocated directly behind it), try
// EXEC PGM=ICKDSF
//DD1 DD DISP=SHR,UNIT=3390,VOL=SER=xxxxxx
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
REFORMAT UNIT(1234) DDNAME(DD1) VERIFY(xxxxxx) NEWVTOC(cc,hh)
UNIT must specify the address of the offline device to be reformatted
where cc,hh is a valid cylinder head address (note disk must be offline for this version) "ANY" can be substituted for cc,hh and then the system will decide where to place it |
