Serviceguard Version A.11.16 Release Notes, 2nd Edition, September 2004

Serviceguard Version A.11.16 Release Notes, Second Edition
What’s in this Version
Chapter 110
• Clusters and packages can now be configured through Serviceguard’s
graphical user interface, Serviceguard Manager. This interface now
replaces all the functionality of SAM Cluster Tool. The Cluster Tool
in SAM has been discontinued with the A.11.16 version of
Serviceguard.
• A new parameter, Network Failure Detection, gives users a choice
about how a network monitor decides to declare a LAN card down.
• A new product, Serviceguard Extension for Faster Failover, can be
used with Serviceguard version A.11.16. The Release Notes are
posted at http://docs.hp.com/hpux/ha. At the same location,
there is a new technical white paper, Optimizing Failover Time in a
Serviceguard Environment, that tells you how you might reduce
failover time with or without the purchased product.
Serviceguard A.11.16 supports the same configurations as previous
versions, with these exceptions:
• Single-ended SCSI disk devices are no longer supported as cluster
lock devices. Configurations which require a single-ended SCSI
cluster lock device cannot upgrade beyond Serviceguard version
A.11.15.
• cmclnodelist is no longer used for access, except as a bootstrap to
first configure a cluster. It has been replaced by Access Control
Policies in the configuration files. Once a cluster configuration file
exists, all non-root users must be listed in an access policy in that file
or in a package configuration file.
• If Serviceguard Extension for Faster Failover (SGeFF) is installed,
there is a new option in the cluster configuration file to enable or
disable SGeFF.
• A new parameter, Network Failure Detection, will let you change the
way network failures are determined. The default is the same
method used in earlier versions.
• On the September 2004 update to HP-UX 11i v2, a cluster can have
nodes with HPIntegrity servers or HP 9000 servers, or both.
