HP Serviceguard Quorum Server Version A.04.00 Release Notes, March 2009

Running the Quorum Server
NOTE: If you have just installed the quorum server, or if you are adding new cluster
nodes, or implementing the alternate-subnet functionality (for a cluster running a
version of Serviceguard that supports it; see “Compatibility with Serviceguard Versions”
(page 12)) you must update the authorization file; see “Creating and Updating the
Authorization File” (page 22).
You must have root capability to run the Quorum Server. On a single system, configure
the Quorum Server to start up when the system on which it is installed restarts or
reboots. Create an entry such as the following in the /etc/inittab file:
• For HP-UX:
qs:345:respawn:/usr/lbin/qs >> /var/adm/qs/qs.log 2>&1
• For Red Hat Linux (all in one line):
qs:345:respawn:/usr/local/qs/bin/qs >> /var/log/qs/qs.log
2>&1
• For SUSE Linux:
qs:345:respawn:/opt/qs/bin/qs >> /var/log/qs/qs.log 2>&1
Start the Quorum Server as follows:
init q
Verify the Quorum Server is running by checking the qs.log file. (Recommended log
pathnames are in Table 1-2 (page 21).)
For HP-UX, enter: cat /var/adm/qs/qs.log
For Linux, enter: cat /var/log/qs/qs.log
The log should contain entries such as the following, indicating that the Quorum Server
has started:
Oct 04 12:25:06:0:main:Starting Quorum Server
Oct 04 12:25:09:0:main:Server is up and waiting for connections at port 1238
Creating and Updating the Authorization File
The Quorum Server reads the authorization file when it starts up. You need to create
the file, on the system where the Quorum Server software resides, when you first install
the Quorum Server, and update it when you add nodes to a cluster the Quorum Server
serves, or add or change the IP addresses or hostnames by which the nodes communicate
with the Quorum Server.
On an HP-UX system, the authorization file must be /etc/cmcluster/qs_authfile.
On a Red Hat Linux system, it must be /usr/local/qs/conf/qs_authfile.
On a SUSE Linux system, it must be /opt/qs/conf/qs_authfile.
