Sorry for the delay in response but ...

(1)  haview

In fact I have never gotten haview to work with NetView.

Previously I had an HACMP cluster  on RISC/6000 39H's under AIX 4.3.2 and HACMP 
4.3 with NetView 5.1.2 and the HACMP support desk told me that they did not 
support haview with that version of NetView, only NetView 5.1.1.  I haven't 
checked recently so this may be out-of-date.

Now, I am in the process of building an HACMPE/S cluster on 2-way SMP F-50s 
under AIX 4.3.3 and HACMP 4.3 for NetView 5.1.2, Tivoli framework 3.6.1, 
Optivity 8.0.1 and Cisco Essentials v 2.1 and CWSI Campus v 2.3.  (In case you 
are wondering, I am trying HACMPE/S in anticipation of using this version 
instead of classic HACMP for making other applications highly available on our 
SP.  Since I know the behavior of Tivoli/NetView under classic HACMP during 
failovers, I can check out HACMPE/S and how its internals work.)

Since haview seems such a pain, I just load the HACMP MIB into NetView, define 
an enterprise correponding to its OID and then customize the traps.  When any 
cluster state change occurs, the trap is issued to the NetView host and appears 
in the control desk.  In this way I know the status of the cluster.

(2)  Tivoli framework installation

You asked about clarifying the Tivoli framework installation.  I install the 
Tivoli framework in a shared external filesystem of its own, i.e. lvtivoi & 
/tivoli, alongwith NetView, i.e. lvnetview  & /usr/OV.  Previously I had 
separate shared external filesystems for /usr/OV/databases and /usr/OV/ebt but 
I now think there is no need for this.

Putting the Tivoli and NetView applications on shared external filesystems in 
an HACMP cluster goes against the recommendations in the IBM Redbooks for 
highly available Tivoli and in the NetView Release Notes which suggest 
installing both on each node on internal disks.  However, I am at a loss on 
what this achieves.  On the other hand, putting both on shared external 
filesystems means that all customizations are automatically sync'd up between 
nodes.  In addition, the recommendation means there must be two separate 
installs, which is a real pain.  When the single install is done on the shared 
external filesystem, I just clone one node to another via Sysback's install 
image option.
