After I added a cluster, two nodes, and two adapters, I ran
"Synchronize Cluster Topology" and got the following error message:
Connection to remote host refused.

Both hosts' IP addresses and names were included in /etc/hosts and
/.rhosts files. Anyone has a clue?

First the simplest one: .rhosts muste have permissions of 600, or it
is ignored.

Next, are you sure systems are using /etc/hosts first? Check
/etc/netsvc.conf. Do the systems allow you to do "rsh" as root between
them?

1) Check that your /.rhosts is permission 600.

2) If that doensn't help, reboot the servers. After updating /.rhosts
for some reason HACMP needs a reboot.

The reboot is usually required because HACMP adds the "godm" service (used
to retrieve remote node configs) to /etc/services but does not "refresh -s
inetd". Pity.

Does this mean you can avoid the reboot by just refressing inetd? If
so, I am going to log a defect. :)

Please do! Ironically, IBM pre-sales is the last place development ever seem to
listen to regarding improving product.

help! hacmp/es+ 4.3.3 ML08 , rlogin or rcp rsh to the other host no
problem and .rhosts is 600 and have reboot the two box when I sync the
topology ,the message is "connection to remote host refused", I have
found that one of the nodes have problem with the "cluster security"
menu,i cannot enter it !!!Anyone has a clue?

SMIT menus are stored in ODM. That plus the fact you're getting
'connection to remote host refused' suggests that both nodes aren't in
sync for its cluster settings.

Make sure that rlogind and rshd is enabled on both nodes in inetd.conf,
and do a 'refresh -s inetd' then a cluster sync. (You may want to consider
stopping HACMP on both nodes to do a sync of the topology *then* of the
resources.)

Yes, we have this problem or rsh not working as expected on a P690 in LPAR
mode with hacmpes.
If you put all your interfaces in the .rhost on both servers it should work.
This is not what you would expect to have to do, but it will get you around
the problem. We are still waiting for IBM to get us a fix for this.
