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

Running the Quorum Server on a Single System
Specifying a Log File
By default, Quorum Server runtime messages go to stdout and stderr. HP recommends that
you create a directory such as /var/adm/qs, then redirect stdout and stderr to a file in this
directory (for example, /var/adm/qs/qs.log) when you start the Quorum Server; see the
sample /etc/inittab entries in the examples below. Recommended pathnames are in Table 1-2
(page 17).
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 10)) you must update
the authorization file; see “Creating and Updating the Authorization File” (page 18).
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 17).)
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(s) 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.
Enter into the file the fully-qualified hostnames, or IP addresses, of all the cluster nodes that will
obtain quorum services from this Quorum Server. Use one line per node, for example:
ftsys9.localdomain.com
ftsys10.localdomain.com
