WLBS start cluster not successful

[Ragnar Heil]

Hello,

I checked a couple of MS-documents and my two nodes (w2k adv.) seems
to be configured well ("WLBS query" looks fine). I am using one NIC
per server. Now I want to start the cluster with the command "WLBS
start cluster" and I get the answer that "cluster" can´t be found or
accessed. Unfortunately I dont have the exact error message handy. If
I "ping cluster", I get the right IP back. "cluster" is the correct
name of a host which is registered in the DNS. event-log doesn´t give
more informations.

any ideas highly appreciated

regards
Ragnar

Mike,

IP of host 1 is 172.17.3.17 (which can be pinged from host 2 which is .18)
"cluster" can be pinged as well

okay, now I run
WLBS start cluster:172.17.3.17

and get this answer:
access to Cluster 'cluster' (172.17.3.21):
no response from Host 172.17.3.17

I really appreciate your fast help!
Ragnar

You should confirm your installation. In this doc is a
pretty good explaination of setting up WLBS.

Thank you for the link to the great document!

We have now decided to use 2 NICs per server.

Please check the following things which I want to do:
- use a different IP each NIC
- the LAN-connection for the 1st NIC is a private one, only
TCP/IP-configuration, no NLB.
- only the "public-LAN-connection" is using NLB, including
Multicast-support.
- private is using gateway, public does not.

thank you!

Hi Ragnar,
I would suggest a few changes, the default gateway in general should be on
the NLB adapter and not the non-balanced (Administrative) adapter. I would
also not use multicast unless it is required.

In general those two recommendations hold true, however they can change
based on your specific configuration. The reason we do not recommend
multicast is that multicast should only be used in single NIC
configurations or if there is an application that is being load balanced
that requires multicast. There are several known issues with some switches
that will drop multicast packets from NLB nodes, so unless you know for
sure that every switch between the NLB cluster and the client accessing the
cluster is compliant it should not be used unless one of the two needs I
stated before matches.
