Peter,

On an H70 AIX 4.3.3 we tried to upgrade as follows:
4.2.1.9 -> 5.1.5.0 -> 5.1.6.0

However, the upgradedb hung at 5.1.5.0 three times.
Conversations with TSM Support said this was a known problem - something to do 
with hanging while examining the Groups table for orphaned System Objects.
In the meantime we installed 5.1.6.0 ( without ever getting the server
up at 5.1.5.0 ) and this was fine. We got a message as below:
 
 ANR9999D iminit.c(1540): ThreadId<0> Started conversion of Groups table at 103 
2 3 9 12 6
 
 then

ANR9999D iminit.c(1826): ThreadId<0> Completed conversion of Groups table at 
103 
2 3 9 19 33

some minutes later. At our server level we have missed the (well documented)
SYSTEM OBJECTS problem introduced at 4.2.2.? . I would guess that if your DB
did contain orphaned SYSTEM OBJECTS then the conversion above might take
longer. Even with a 'clean' DB of 102GB this took several minutes - so have 
patience !

Subsequently we were advised that 5.1.6.1 was a better level and so upgraded
to that.

Tomorrow we are upgrading our other two production TSM servers and we plan 
to go:

4.2.1.9 -> 5.1.6.0 -> 5.1.6.1
