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

For the latest information on supported configurations, see the Serviceguard for Linux
Certification Matrix at the address given under “What Documents are Available for This
Version ” (page 48).
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
(_)
