We were running TSM 5.2.4 on i5/OS PASE.  Since IBM dropped support for
i5/OS PASE for TSM we migrated to a Linux lpar hosted on the same box.
Running a newer version of TSM.  Basically we carved out a Linux lpar out
of the existing i5/os lpar and used the same exact hardware:  5704 card to
IBM 2109-F16 SAN switch to IBM 3582-L23 tape drive.  The time it takes to
fill up a 3582 cartridge dropped from 6 hours to 3.

Just goes to show you that the PASE API's for tape are abominable.  And
IBM freely admits this.
