qs_authfile for Quorum

[Jason Ray]

I have been reading through the serviceguard documentation and noticed that when setting up the quorum server, it says to create the /etc/cmcluster/qs_authfile file "on each node" and enter the names of "all cluster members".

Do you really need the qs_authfile on the nodes as well as the quorum server?

Also, is the cmclnodelist file necessary on the quorum server?

Thanks

The latest Managing Serviceguard manual at
http://docs.hp.com/en/B3936-90100/B3936-90100.pdf - page 206 states:

Installing the Quorum Server
Use the HP-UX swinstall command to install the quorum server,
product number B8467BA, on the system or systems where it will be
running. The quorum server is installed outside of the cluster that it
serves. The quorum server should be installed outside of the cluster that
it serves. More details on installation are found in the Quorum Server
Release Notes for your version of Quorum Server.
The quorum server executable file, qs, is installed in the /usr/lbin
directory. When the installation is complete, you need to create an
authorization file on the server where the QS will be running to allow
specific host systems to obtain quorum services. The required pathname
for this file is /etc/cmcluster/qs_authfile. Add to the file the names
of all cluster nodes that will access cluster services from this quorum
server. Use one line per node, as in the following example:
ftsys9.localdomain.com
ftsys10.localdomain.com




Therefore, only the quorum server needs to have the /etc/cmcluster/qs_authfile created on it.

Note that after you start the quorum server, if you add nodes to the qs_authfile, you must perform '/usr/lbin/qs -update' to cause the running qs program to re-read the qs_authfile and recognize the new nodes.
