Supported Conﬁgurations

Serviceguard NFS supports the following conﬁgurations:

• Simple failover from an active NFS server node to an idle NFS server

node.

• Failover from one active NFS server node to another active NFS

server node, where the adoptive node supports more than one NFS

package after the failover.

• A host conﬁgured as an adoptive node for more than one NFS

package. The host may also be prevented from adopting more than

one failed package at a time.

• Cascading failover, where a package may have up to three adoptive

nodes.

• Server-to-server cross mounting, where one server may mount

another server’s ﬁle systems, and the mounts are not interrupted

when one server fails.

These conﬁgurations are illustrated in the following sections.
