Hi,
Could you please let me know how to find the Largest available Extent on DASD Volume.
I understand that this can be got from V type records, but dont have access to perform DCOLLECT. ISMF is not available too on this LPAR and to add there is no Quickref. I tried IEHLIST LISTVTOC but I think it does not have volume level information, it produced a dataset level detail.
One thing that is available was 3.4 option V Display VTOC information. Could you please let me know how to get this data using REXX.
Thanks, |

Hi,
if you have FILEAID, you can use the following to capture the information you require
| Code: |
//FILEAID EXEC PGM=FILEAID
//SYSPRINT DD SYSOUT=*
//SYSLIST DD SYSOUT=*
//SYSIN DD *
$$DD01 VTOCDSN UNIT=3390,VOLSER=(XXX)
/*
|
where XXX is the prefix of volumes to be listed

Thanks for the response,
but there's no FILEAID either on the LPAR.

Hi,
using this with IEHLIST you can get the information you require at the bottom of the listing
| Code: |
LISTVTOC VOL=SYSDA=XXXXXX,FORMAT

THERE ARE 1359 EMPTY CYLINDERS PLUS 170 EMPTY TRACKS ON THIS VOLUME
THERE ARE 5214 BLANK DSCBS IN THE VTOC ON THIS VOLUME
THERE ARE 286 UNALLOCATED VIRS IN THE INDEX |
870 was the largest extent
Thanks, |

ISMF option 2 DASDLIST, or 6 Storgrp then LISTVOL can also provide this, and both can also be run in a Naviquest batch job form as well.
Quickref S=volmask can as well |

Hi Pete,
Thx for the Naviquest one.
I have done Quickref & ISMF on other LPARs but this one did not have QW & ISMF on'em.

Hi,
I tried the below REXX for IEHLIST REXX,
| Code: |
/*REXX*/
"ALLOC DD(SYSPRINT) NEW REU SPACE(1,1) CYLINDERS RELEASE"
"ALLOC DD(VOL1) VOLUME(ABCD) SHR"
"ALLOC DD(SYSIN) NEW REU"
QUEUE ' LISTVTOC VOL=SYSDA=ABCD,FORMAT'
"EXECIO" QUEUED() "DISKW SYSIN (FINIS"
ADDRESS LINK 'IEHLIST'
"EXECIO * DISKR SYSPRINT (STEM RESULT. FINIS"
"FREE DD(SYSIN,VOL1,SYSPRINT)"
DO I = 1 TO RESULT.0
SAY 'RESULT ' RESULT.I
END
EXIT |
But the REXX is failing with,
| Code: |
IKJ56701I MISSING DATA SET NAME+
IKJ56701I MISSING NAME OF DATA SET TO BE ALLOCATED
IKJ56247I FILE VOL1 NOT FREED, IS NOT ALLOCATED
|
Please let me know how to correct the Alloc statement.
Thanks, |

Hi,
Below is the trace log,
| Code: |
5 *-* "ALLOC DD(VOL1) VOLUME(ABCD) SHR"
>>> "ALLOC DD(VOL1) VOLUME(ABCD) SHR"
IKJ56701I MISSING DATA SET NAME+
IKJ56701I MISSING NAME OF DATA SET TO BE ALLOCATED
+++ RC(12) +++ |
Thanks, |

| The syntax diagram in section 1.7.4 of the TSO/E Command Reference manual indicates that the DSNAME parameter is not optional in the ALLOC command. |

Hi Robert,
The JCL statement was
| Code: |
| //VOL1 DD VOL=SER=ABCD,DISP=SHR |
So I thought I could code the Alloc statement that way.
What could be the alternative?
Thanks, |

'cuse my ignorance,
but I thought you did not need to do ALLOC in a REXX run in batch,
if the DDNAME - used on the EXCIO - was allocated by JES - by virtue of a DD Statement in the Step JCL |

| Vasanth, there are some differences between TSO ALLOC commands and JCL DD statements. You've just found one of them. |

Hi,
I am trying the foreground option in REXX with TSO EX ' '.
Batch job worked for IEHLIST, but interactive REXX was having the error.

When you code JCL statement
| Code: |
| //VOL1 DD VOL=SER=ABCD,DISP=SHR |
you are also getting a DSNAME but it's a temporary, system generated name. |
