WLM and Service Guard (two node cluster)

[Elena Garcia]

Hello all,

We are setting up a WLM environment consist of a two nodes cluster with Service Guard. Both servers has iCOD to allow activate 8 more CPUs = in case they are needed =.

Although we are able to setup a configuration, we can not monitor this configuration through the gui.


If I setup a partition with only one server I always get this error when I try to activate:

<<<<< Unknown partition in configuration file: xxxxx


The fact is that I think we do not have to set a a partition, as each cluster node consists of a single server. However, when I try to monitor a WLM configuration the GUI report an error because there are no partition set definitions and does not allow us to moniot WLM through the GUI and be able to see the graphics.

How can I monitor WLM through the Graphical Interface without partitions?

Can anyone help me?.

Thanks in advance.

Hello Elena. A 'partition set' is defined as a group of systems with at most one global arbiter daemon, wlmpard, running between them. These "systems" can be single servers (as in your case), vpars or npars for example.

The message you encountered comes from the wlmpard daemon. If I am understanding your setup correctly, you do not need to use wlmpard at all. You are simply configuring WLM on two separate systems in a SG cluster. Through the GUI, you can put both systems in the same partition set by selecting "Add" and:
1) entering the first system info
2) selecting "Add Host"
3) entering the second system info
2) selecting "Add Host"
5) selecting "OK"
Or you can put them in separate partition sets by selecting "Add", entering the system info, selecting "Add Host" then "OK", and repeating for the other system.

Also, make sure you are not specifying the primary_host keyword in your wlmd configuration files and that the /opt/wlm/bin/wlmcomd daemon is running on each server.

Hope this helps. If not, please feel free to send an email to wlmfeedback@rsn.hp.com where I can help you further.

Jonathan,

Many thank for your reply. Now, I can see the statics through the gui.The problem was that I was always trying checking the "primary host" box (although I only want to see a single server).

Best regards.

Many thanks.
