Description

When trying to POFFLOAD to a Dynam/T controlled tape using the new format of the command:

// TLBL xxxx,'dsn.name,Z,DL'
(where Xxxx is the DTFNAME specified on the TLBL= parameter of the POFFLOAD command and dsn.name is the CA Dynam/T data set name)

the POFFLOAD command fails with the IBM error message:
1QB5I INTERNAL MACRO CALL FAILED IN PHASE=xxxxxxxx, RC=rrmm taskid,cuu
Typical values seen are:
1QB5I INTERNAL MACRO CALL FAILED IN PHASE=IPW$$OT , RC=0C53 L-OFF,CAA
or
1QB5I INTERNAL MACRO CALL FAILED IN PHASE=IPW$$OT , RC=0C50 R-OFF,800

Solution

You must add the labels for the POFFLOAD tapes with options DL,Z to the standard labels AFTER the EXEC CASAUTIL statement has been processed.
This is because the CA DYNAM options must be stripped off before the label is added to standard labels..

If this is not done, it will cause the message 1QB5I to be issued from POWER.
The CA DYNAM option
,Z
allows CA Dynam/T to detect POWER closing the POFFLOAD tapes and
,DL
Deletes the label for the file at the close of the file.
You must also add a PERMANENT assign to the AUDIT and CATALOG of CA DYNAM into the POWER startup.

Please review the section in the CA Dynam 7.1 User Guide, page 2-80, entitled "Controlling Single and Multi-Volume POWER Offload Tapes" for further information. See also related Knowledge Documents TEC448231 and TEC430923.
