HP Serviceguard for Linux Version A.11.19 Release Notes, July 2009

Example
1. mv $SGCONF/AutoPass/LicFile.txt
$SGCONF/AutoPass/LicFile.txt.sav
2. cp /mystuff/mySGlicense $SGCONF/AutoPass/LicFile.txt
3. cmcheckconf –v –C <cluster.conf>
where <cluster.conf> is the configuration file used to create the existing cluster.
4. • If the license is valid, keep the new license file $SGCONF/AutoPass/
LicFile.txt
You can delete the old license file $SGCONF/AutoPass/LicFile.txt.sav.
• If the license is invalid, restore the original license:
mv $SGCONF/AutoPass/LicFile.txt.sav
$SGCONF/AutoPass/LicFile.txt
Installing the Quorum Server
If you choose to use a Quorum Server rather than a lock LUN for tie-breaking, install
the Quorum Server software on a system outside the cluster. The Quorum Server
software is on the Serviceguard for Linux CD. Updated versions may be available from
http://www.hp.com/go/softwaredepot -> High Availability -> Quorum
Server.
CAUTION: If you are upgrading both the Quorum Server and Serviceguard for Linux,
upgrade the Quorum Server before you upgrade Serviceguard. This is especially
important if you are using an Alternate Quorum Server Subnet (page 32). See “Quorum
Server Upgrade Required if You Are Using an Alternate Address” (page 13).
See the Quorum Server Version A.04.00 Release Notes for a complete description of the
Linux installation and configuration process; you can find them at http://
docs.hp.com -> High Availability -> Quorum Server. There is more
information about the Quorum Server in Managing HP Serviceguard for Linux.
Setting Permissions on the /root/.rhosts File
The /root/.rhosts file must not allow write access by group or other. If /root/
.rhosts file write permission is enabled for other or group, HP Serviceguard for
Linux commands will fail, logging a “Permission denied for user” message.
This situation can arise when the Serviceguard remote security file,$SGCONF/
cmclnodelist, is not used and remote node security is resolved by means of .rhosts.
