Here is the jcl to init tapes..good luck..Mace //SYSPLJM1 JOB (0007,SYSTEM),MACIOCE,CLASS=I,MSGCLASS=X,

The labels are written at the density of the drive ... so if they don't match, the labels need to be re-written. Most TMS's always re-write the labels (VM:Tape, Dynam/T, etc.) so this is not a problem for the end user or application. However, you might run into a problem if a 3590 CART init'd at a higher density (3590H) is selected for SCRATCH on a lower density drive (3590E) because the lower density drive will not be able to read the VOL1 written at the higher density ... you'll likely get a "NON-COMPAT" error.

The data portion at that specified. I know not if this is still true. -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Mark Pace Sent: Friday, January 19, 2007 8:31 AM To: [email protected] 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!
