Q1: Services AM & PM vs AM-PM Q2: Disable IPv6

Question1:

I did a default installation and it left me with 3 seperate services and I was just wondering if it is overkill.

sm_services snip-it

sm_service install --force --name=ic-am-pm-server "--dname=EMC Smarts Availability and Performance Manager Server" ...

sm_service install --force --name=ic-am-server "--dname=EMC Smarts Availability Manager Server" ...

sm_service install --force --name=ic-pm-server "--dname=EMC Smarts Performance Manager Server"

So can I just remove the separate AM and PM services and utilize the single AM-PM service?

If so, is there any steps that I need to follow in order to keep it from complaining about the service being disconnected (i.e. removal INCHARGE-AM under global manager) ?

Question 2:

Is there a way to disable the IPv6 managers? For example INCHARGE-AM [IPv6] or INCHARGE-AM-PM [IPv6]

Thanks in advance!
