Hello everyone,
Is there any way to get on Dcollect only volumes on disnew status for a storage group?
I need to get datasets that are on volumes on Disnew.
What I am doing now, is getting an ISMF report, manually removing all volume on a different status as Disnew and then with that list of volume I run the dcollect + naviquest to format sysout.
I am trying to find out a shorter way to get that list of dataset residing on Disnew volumes.
Thanks!

It should be possible to get the information from IDCAMS DCOLLECT w/ STOG and SMSDATA parameters. You would need the D and VL Records first. Do a SORT as post-processor using JOINKEYS when then condition is met in a VL record (for the Volume DISNEW) and the Volume from the D record.

If you have only one System in DFSMS defined, I would go w/ this approach.

Thanks for your quick response! I was trying to get VL record with a dcollect for 5 volumes as input and I get information of all SMS volumes on the system. I just specified on JCL the following.

//SYSIN DD *
RECORD=VL

And it has very intensive CPU usage. Do you know if I have to specified any parameter to get only information relative to the input? I didn't find anything. Thanks again.

Do as I say and it works as expected.
Code:
//DCOLL    EXEC PGM=IDCAMS                                           
//SYSPRINT DD SYSOUT=*                                               
//DCOUT    DD DISP=(NEW,PASS,DELETE),UNIT=SYSALLDA,                   
//            SPACE=(1,(2,1),RLSE),AVGREC=M,         
//            DSORG=PS,RECFM=VB,LRECL=32756,BLKSIZE=0                 
//SYSIN    DD *                                                       
  DCOL +                                                             
    OFILE(DCOUT) +                                                   
    SMS(ACTIVE) +                                                     
    STOG(SGHSM) +                                                     
    NOV                                                               
/*                                                                   
//WHATEVER EXEC PGM=ICEMAN                                           
//F1       DD DISP=(OLD,PASS),DSN=*.DCOLL.DCOUT,VOL=REF=*.DCOLL.DCOUT
//F2       DD DISP=(OLD,PASS),DSN=*.DCOLL.DCOUT,VOL=REF=*.DCOLL.DCOUT
//SYSOUT   DD SYSOUT=*                                               
//SORTOUT  DD SYSOUT=*                                               
//SYSIN    DD *                                                       
  OPTION COPY                                                         
  JOINKEYS F1=F1,FIELDS=(5,6,A)                                       
  JOINKEYS F2=F2,FIELDS=(5,6,A)                                       
  REFORMAT FIELDS=(F1:5,6,F1:11,44)                                   
  OUTFIL FNAMES=(SORTOUT),                                           
    REMOVECC,                                                         
    BUILD=(1,6,X,7,44)                                               
  END                                                                 
/*                                                                   
//JNF1CNTL DD *                                                       
  INCLUDE COND=(9,2,CH,EQ,C'D ')                                     
  INREC BUILD=(1,4,83,6,29,44)                                       
  END                                                                 
/*                                                                   
//JNF2CNTL DD *                                                       
  INCLUDE COND=(9,2,CH,EQ,C'VL',AND,173,1,BI,EQ,B'.....101')         
  INREC BUILD=(1,4,31,6)                                             
  END                                                                 
/*


Will give for example..
Code:
HSMVOL SYS1.VVDS.VHSMVOL                     
HSMVOL HSM.EDITLOG                 
HSMVOL HSM.OCDS.DATA               
HSMVOL HSM.OCDS.INDEX

..because only that Volume is in DisNew state in StorageGroup SGHSM. Pretty simple if you have only ONE system in the SMSPLEX. Otherwise you possibly need other offsets for the SMS state.

Check for the Naviquest job SYS1.SACBCNTL(ACBJBAI4) on your system. This job runs ISMF in Batch to list volume information, which can be by volser mask or storgrp name. In the job you need to include the CFVOLST parameter to get the volume status. Then use that volume list formatted as input to list the datasets on the volumes identified.
e.g.
//DASDLST EXEC ACBJBAOB,
// PLIB1=SYS1.DGTPLIB,
// TABL2=userid.TEST.ISPTABL
//SYSTSIN DD *
PROFILE PREFIX(userhlq) MSGID
ISPSTART CMD(ACBQBAI4 +
SAVE SGVOL QSAVE(VOLSTAT) +
SPCDATA(Y) PHYDATA(Y) +
STORGRP(sgname) CFVOLST ) +
NEWAPPL(DGT) BATSCRW(132) BATSCRD(27) BREDIMAX(3) BDISPMAX(99999999)

You may also be able to get the DSN list using another Naviquest step as per SYS1.SACBCNTL(ACBJBAI2) but I haven't tried that to see if you can specify multiple volsers.

I do not see the need to prefer an ISPF based service (NAVIQUEST) over DCOLLECT/DFSORT here.

@Pete: CFVOLST - CF Volume status ENABLED/QUIESCING/QUIESCED, which is certainly NOT what the TS has intended.
