HP Serviceguard for Linux Version A.11.18 Release Notes, 2nd Edition, March 2009

Installing Quorum Server
If you choose to use a Quorum Server rather a lock LUN for tie-breaking, install the
Quorum Server software on a system outside the cluster. The Quorum Server software
is on the Serviceguard for Linux CD. Updated versions may be available from http://
www.hp.com/go/softwaredepot ->High Availability ->ServiceGuard
Quorum Server.
See the Quorum Server Version A.03.00 Release Notes for a complete description of the
Linux installation and configuration process; you can find them at http://
docs.hp.com -> High Availability -> Quorum Server. There is more
information about the Quorum Server in Managing HP Serviceguard for Linux.
Setting Permissions on the /root/.rhosts File
The /root/.rhosts file must not allow write access by group or other. If /root/
.rhosts file write permission is enabled for other or group, HP Serviceguard for
Linux commands will fail, logging a “Permission denied for user” message. This
situation can arise when the Serviceguard remote security file,$SGCONF/
cmclnodelist, is not used and remote node security is resolved by means of the
.rhosts facility.
NOTE: /etc/cmcluster.conf contains the mappings that resolve the symbolic
references to$SGCONF, $SGROOT, etc., used in these Release Notes. See “Understanding
the Location of Serviceguard Files” in Chapter 5 of the Managing HP Serviceguard for
Linux manual for details.
For more information about configuring security for prospective cluster nodes, as well
as for an existing cluster, see Chapter 5 of Managing HP Serviceguard for Linux.
