New Features for A.11.20
• New commands (and equivalent capabilities with Serviceguard Manager) provide a quick
and easy way to configure and deploy a Serviceguard cluster.
See “Easy Deployment” (page 18).
• A new capability in Serviceguard allows a package's applications to remain running
(unmonitored) while you do maintenance on the node or cluster on which the package is
running.
See “Halting a Node or the Cluster while Keeping Packages Running (Live Application Detach)”
(page 19).
• A new type of device file allows you to deploy a set of persistent device special files that is
consistent across the cluster, eliminating to risk of name-space collisions amongst the cluster
nodes. These new device special files are called cluster device special files or cDSFs.
See “Cluster-wide Device Special Files (cDSFs)” (page 20).
• New Serviceguard capabilities allow you allow you to check the soundness of the cluster
configuration, and the health of its components, more thoroughly than you could in the past,
and to do so at any time, rather than only when changing the configuration of the cluster or
its packages.
See “Checking the Cluster Configuration and Components” (page 21).
• You can now you can use NFS-mounted (imported) file systems as shared storage in packages.
See “NFS-mounted File Systems” (page 23).
