Customer has installed Tivoli Advanced Allocation Manager (TAAM) and is using PDSMAN. Ran into the following errors:

Some features of TAAM may not work well with features within PDSMAN, these should be tested and researched.

z/OS any level

PDSM 7.7 and above

Tivoli Advanced Allocation Manager

In the PDSMINT options data set for PDSMAN is the following option

$BSI FASTSTOW=Y

This should be changed to

$BSI FASTSTOW=N

In the PDSM Administration Guide page 101 describes the control statement.

This parameter controls the operation of the PDSMAN FastStow facility, a high-performance replacement for PDS STOW operations that are otherwise handled by the operating system STOW routines. FastStow support is of greatest benefit where large numbers of STOW operations may be performed against a library, such as may occur during PDSM02 processing of libraries containing many members.

Y - Enable FastStow support globally.
R - Enable FastStow support only for those libraries which are matched by a     $UPDATE rule which specifies FASTSTOW=Y. Using this option permits FastStow implementation on a library-by-library basis.

N- FastStow support not required (default).

This is not a required function.
