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

Quorum Server Upgrade Required if You Are Using an Alternate Address
If you are using an Alternate Quorum Server Subnet (page 33), you must upgrade the
Quorum Server to version A.04.00 before you upgrade the cluster to Serviceguard
A.11.19.
CAUTION: If you fail to do this, the upgraded cluster will be running without a cluster
lock until you have upgraded the Quorum Server.
Serviceguard Manager Available from the System Management Homepage (SMH)
For details, see “About Serviceguard Manager” (page 24).
NOTE: The earlier, station-management (or standalone) version of Serviceguard
Manager (A.05.01) is obsolete. The last version of Serviceguard for Linux that supports
that product is A.11.16.
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.
ipnodes Entries Needed in /etc/nsswitch.conf
Beginning with version A.11.19, Serviceguard uses calls that require ipnodes entries to
be configured in /etc/nsswitch.conf. See “Safeguarding against Loss of Name
Resolution Services” in Chapter 5 of Managing Serviceguard for Linux for more
information.
High Availability Consulting Services
Because Serviceguard configurations can be complex to configure and maintain, HP
recommends that you use its high availability consulting services to ensure a smooth
installation and rollout; contact your HP representative for more information. You
should also work with your HP representative to ensure that you have the latest
firmware revisions for disk drives, disk controllers, LAN controllers, and other
hardware.
