HP Serviceguard Quorum Server Version A.04.00 Release Notes, March 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:
• Allows Serviceguard A.11.19 cluster nodes to communicate with the Quorum
Server on an alternate subnet; see “Using Alternate Subnets” (page 17).
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.
NOTE: See “Setting Quorum Server Parameters in the Cluster Configuration
File” (page 17) for special instructions.
HP Serviceguard Quorum Server A.04.00 supports Serviceguard versions A.11.14 and
later on HP-UX and Linux, but the 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”.
NOTE: This version of the Quorum Server does not run on Red Hat 3 Linux.
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
(_)
