Do I have to:
backup the volume.
v volume offline.
re-init volume (with bigger vtoc).
v volume online
restore back?
The volume is NOT sms managed.
Is there another way?

Need to read ICKDSF manual! Can be driven via ISMF panels or batch.

2.14.4.1.5 Refreshing the VTOC and index
| Use the REFVTOC
parameter to rebuild the VTOC in its current location,
| using the same track size. The Fmt4 DSCB is rebuilt to reflect the real
| device capacity. If the VTOC is an indexed VTOC the index data set will
be
| deleted. If the device is online to MVS, the index data set will be
| rebuilt to reflect the VTOC changes.
The following is an example of refreshing the VTOC and the Index on an
online MVS volume, using the REFVTOC parameter:
//EXAMPLE JOB
// EXEC PGM=ICKDSF
//VOLDD DD DISP=SHR,UNIT=3380,VOL=SER=TMP121
//SYSPRINT DD SYSOUT=A
//SYSIN DD *
REFORMAT DDNAME(VOLDD) VERIFY(TMP121) REFVTOC
/*
An example of the ICKDSF output from the above job:
ICK00700I DEVICE INFORMATION FOR 0B00 IS CURRENTLY AS FOLLOWS:
PHYSICAL DEVICE = 3380
STORAGE CONTROLLER = 3990
STORAGE CONTROL DESCRIPTOR = EC
DEVICE DESCRIPTOR = 1E
ICK04000I DEVICE IS IN SIMPLEX STATE
ICK01520I THE VTOC-INDEX WAS DELETED
ICK01314I VTOC IS LOCATED AT CCHH=X'0000 0001' AND IS 200 TRACKS.
ICK01502I BUILDIX FUNCTION STARTED
ICK01503I 0B00 REQUEST RECEIVED TO CONVERT VTOC TO IXFORMAT
ICK01504I 0B00 VTOC FORMAT IS CURRENTLY OSFORMAT, REQUEST ACCEPTED
ICK01508A 0B00 SHOULD CONVERSION PROCEED? REPLY U TO CONTINUE, ELSE T
