Using WORM Media with BRMS

Troubleshooting


Problem

This document explains how Write Once Read Many (WORM) works with BRMS.

Resolving The Problem

BRMS does support Write Once Read Many (WORM) media. This is set up in the media class, WRKCLSBRM,

The Write Once media prompt identifies whether the media in this class should be treated as if the volumes can be written only once. You would set this value to *YES if the type of media being used with this class is Write Once Read Many (WORM).

The following identifies the operating characteristics of WORM media.

oFile sequences on WORM media cannot be reused.
oOnly new file sequences can be added to WORM media until the volume is filled.
oWORM media cannot be re-initialized once used.
oIf the WORM volumes are not added to a media class with WORM=*YES, BRMS will not know it is a WORM cartridge and consider it a valid backup candidate. Therefore the customer should be sure to add the WORM volumes to a media class that specifies WORM=*YES.

If a WORM cartridge is expired and attempted to be overwritten, message CPF41B1 - Data overwrite not allowed would be posted.
