In days of old, the volume label was written at the lowest density of
the tape. The data portion at that specified. I know not if this is
still true.

Subject: Re: 3590J to 3590H
LONG STORY- but I won't bore everyone with it. 4 days later and
the new 3590s are running.
Had specialist tell me I needed to mark all my migration/backup
volumes as full.
Also to set readcompatability in the Attributes section of RMM.
So I wanted to re-int, label, a tape to see if it writes on the
tape at the new density. So I dumped the label of a volume and it says
for density - 3590. I re-int the volume and it still says 3590 for the
density. So I don't know if it worked or not. I did this all under VM
because of my new problem.
How do you initialize an existing tape under z/OS? I tried to
use DITTO INT function. But it tells me I can't do that to a Scratch
tape. Well I sure don't want to do it to a Master tape! See my JCL
below.
//DTOBAT PROC
//DTOBAT EXEC PGM=DITTO
//STEPLIB DD DSN=DIT.V1R3M0.SDIT MOD1,DISP=SHR
//SYSPRINT DD SYSOUT=*
//SYSABEND DD SYSOUT=*
//SYSDUMP DD SYSOUT=*
// PEND
//*
//INITTAPE EXEC DTOBAT
//TAPE DD DISP=(SHR,KEEP),DSN=DUMMY,LABEL=(,BLP),UNIT=CART,
// VOL=(,RETAIN,SER=ML5000)
//SYSIN DD *
$$DITTO REW LABEL=BLP,OUTPUT=TAPE
$$DITTO INT OUTPUT=TAPE,VOLSER=ML5000
$$DITTO RUN OUTPUT=TAPE
