Isn't TSM v4.2 for OS/390 an option for you. It could leverage your current
ESCON 3590 inverstments with the new functionality.
If you are one of the shops which prefer one-time charge for mainframes,
are Linux-oriented and avoid MVS, then in my personal opinion you nearly
hit the main reason not to have recent TSM version on VM.
Looking for larger DLT library is not an option only for Veritas. TSM on
AIX will be more than happy to serve you with larger library. And if you
need to have new one instead of expanding existing library I would
recommend you to investigate LTO as well.
Veritas on Intel cannot compete with TSM on AIX with right arguments. So
prepare for the battle and enjoy the victory.

Subject:        migration options

We are trying to determine what our options are in moving
forward from tsm 3.x to 4.x.   We have split our load across
a TSM AIX 3.7 system and a TSM VM 3.1.  We also have Veritas
running for  an NT Exchange Server.

Our Intel folks have been trying to get us to move in the Veritas
direction, however that tape system is quite limited (Small
DLT library).  The AIX and VM are sharing a 3494/3590-E1A library
with around 200-300 tapes in it.

Our main problem is that we have invested heavily in ESCON connections
to the 3494 lib but TSM VM seems to have been deadended for some time.
What have other VM TSM users moved to?  Again with our hardware
the OS/390 TSM seems to be the only other possibility, unless
Tivoli comes out with a LINUX/390 Server.  The VM version has
been so trouble free and so easy to manage its really hard to
understand Tivoli's determination to eliminate the platform.
