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 and
A.04.00.01. A.04.00 is supported for RHEL versions till 6.0 and A.04.00.01 is supported for
RHEL 6.0. This version supports Serviceguard versions A.11.14 and later on HP-UX and Linux,
and provides the following new capabilities:
• Quorum Server version A.04.00.01 adds support for RHEL 6.
• Serviceguard A.11.19 and later 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 of quorum server is required if you intend to use an alternate
subnet with Serviceguard A.11.19 and later, and must be installed before you upgrade an
A.11.18 cluster using an alternate subnet to A.11.19 and later.
• Allows Serviceguard A.11.19 cluster nodes to communicate with the Quorum Server using
IPv6 subnets.
For more information, see “Setting Quorum Server Parameters in the Cluster Configuration
File” (page 14).
• 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 a 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 must 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 9); for instructions,
see “Configuring and Running the Quorum Server” (page 15).
