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

1 HP Serviceguard Quorum Server Version A.04.00 Release
Notes
Announcements
This edition of the release notes provides information about Quorum Server version A.04.00.
This version supports Serviceguard versions A.11.14 and later on HP-UX and Linux, and provides
the following new capabilities:
• Allows Serviceguard A.11.19 cluster nodes to communicate with the Quorum Server on an
alternate subnet; see “Using Alternate Subnets” (page 13).
IMPORTANT: This version is required if you intend to use an alternate subnet with
Serviceguard A.11.19, and must be installed before you upgrade an A.11.18 cluster using
an alternate subnet to A.11.19.
• Allows Serviceguard A.11.19 cluster nodes to communicate with the Quorum Server using
IPv6 subnets.
See “Setting Quorum Server Parameters in the Cluster Configuration File” (page 14) for
instructions.
• Supports IPv6–only Quorum Servers.
A system configured to use only IPv6 addresses can provide quorum service to a Serviceguard
cluster that is configured as an IPv6–only or mixed-mode cluster. See “About Hostname
Address Families: IPv4-Only, IPv6-Only, and Mixed Mode” in Chapter 4 of the latest version
of Managing Serviceguard or Managing Serviceguard for Linux.
IMPORTANT: These alternate-subnet and IPv6 capabilities are available only with Serviceguard
versions that support them. See “Compatibility with Serviceguard Versions” for more information
and restrictions.
The Quorum Server software can run on either an HP-UX or Linux system. See “System
Requirements and Recommendations”.
Cluster Name Restrictions
The following characters must not be used in the cluster name if you are using the Quorum
Server: at-sign (@), equal-sign (=), or-sign (|), semicolon (;).
These characters are deprecated, meaning that you should not use them, even if you are not
using the Quorum Server, because they will be illegal in a future Serviceguard release. Future
releases will require the cluster name to:
• Begin and end with an alphanumeric character
• Otherwise use only alphanumeric characters, or dot (.), hyphen (-), or underscore (_)
Using this Version
For support information see “Compatibility with Serviceguard Versions” (page 10); for
instructions see “Configuring and Running the Quorum Server” (page 16).
