I'm not sure if this has been covered before, but IPXSPX, NETBIOS and SNA are 
no longer valid COMMunication METHODs in your dsmserv.opt in v4.1  We found out 
the hard way after upgrading from v3.1 to v3.7 then to v4.1 yesterday.  Our 
three hour install ended up being 11 hours after having to downgrade back to 
v3.7.  

We did not find any references to this in any of the v4.1 documentation, but a 
support call to Tivoli did confirm that these are no longer supported 
communication methods.

I hope this helps others of you trying to decide whether to upgrade to v3.7 or 
v4.1.

This brings up a question.  Does anyone know how long v3.7 will be supported?
