HP Serviceguard Linux NFS-Toolkit-A.03.03.00 User Guide (696981-001, June 2012)
2 Supported configuration
This section explains the following supported configurations for NFS toolkit packages:
• Failover from an active NFS server node to an idle NFS server node.
• Configuring two NFS toolkit packages using NFSv4 protocol.
• Coexistence of NFS toolkit package configured to use NFSv3 protocol and NFS package
configured to use NFSv4 protocol on the same node.
Failover from an active NFS server node to an idle NFS server node
Figure 1 Failover from an active to idle NFS server node
Figure 1 (page 6) illustrates a failover from an active NFS server node to an idle NFS server
node.
Node_A is the primary node for NFS server package Pkg_1. When Node_A fails, Node_B adopts
Pkg_1. In this case, Node_B locally mounts the file systems associated with Pkg_1 and export
directories mounted on a filesystem. Both Node_A and Node_B must have access to the disks that
holds the file systems for Pkg_1.
