Question:

 I am testing POFFLOAD on the 5.2 system. 

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

Answer:

To control single and multi-volume POWER Offload tapes with CA 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 CA Dynam/T data set name.

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

tapes.

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