I'm running TSM3.7.1 on OS/390 2.6 and have no problem with dropping TCPIP
while *SM is up. Last week we had a disaster recovery test at Sungard and
our network people bounced TCPIP lots of times while *SM was up. When they
got the routing correct, I was able to just go about my business of restores
without having to bounce *SM. You may want to check the PSP buckets for your
version of TCPIP and *SM. With the 3.2 versions of TCP and before there were
a lot of TCPIP fixes for *SM.
