Hi all The DISKMAP is great.
We init our DASD as the following IBM recommended options DEVICE VTOC INDEX -- ------ ------- ------- 3390-1 0,1,0029 02,0,006 3390-2 0,1,0059 04,0,012 3390-3 0,1,0074 05,0,015 3390-9 0,1,0224 15,0,045 3390-27 0,1,0672 45,0,135 3390-54 0,1,1344 90,0,270 The VTOC index always follow the VTOC Does it mean there isn't any free space available following the current location of the VTOC? Thanks a lot! Best Regards, Jason Cai From: Nims,Alva John (Al) Date: 2017-11-09 22:23 To: IBM-MAIN Subject: Re: VTOC extended IEHLIST of the VTOC? One of the DISKMAP programs at CBTTAPE.ORG?

There must be free space available to allow for contiguous expansion of the VTOC. If there isn't free space available following the current location of the VTOC, an error message will be issued. 'n' must be greater than the old VTOC size. Before running REFORMAT EXTVTOC(n),is there any utility or REXX t which could tell whether there is any free space available following the current location of the VTOC? Thanks a lot!
