Products

• Dynam VSE Option

Issue/Introduction

You are testing POFFLOAD on a 5.2 system. 

It opens a DYNAM tape with no problem but does not catalog the tape on completion. 

Resolution

To control single and multi-volume POWER Offload tapes with Dynam/T, do the following:

1. Define a tape device in the IPL procedure that does NOT exist.

For example:

ADD CAA,3480

2. Define that device to CA Dynam/T by using CACCDBU0 or on CUI screen CAYD1214.

For example:

// EXEC CACCDBU0
ALT DTOPTIONS CPU(*) PWRCUU(CAA) REFRESH(YES)
/*

3. Include the following TLBL in either standard labels or in partition standard labels in the POWER partition:

// TLBL xxxx,'dsn.name,Z,DL'

where:

xxxx is the DTFNAME specified on the TLBL= parameter of the POFFLOAD command.

dsn.name is the Dynam/T data set name.

,Z allows Dynam/T to detect POWER closing the POFFLOAD tapes.

,DL Deletes the label for the file at the close of the file.
