MC/ServiceGuard NFS Toolkit
Multi-Computer/ServiceGuard Network File Server (MC/ServiceGuard NFS) Toolkit
uses MC/ServiceGuard (MC/SG) to set up highly available NFS servers. An NFS server
is a host that “exports” its local directories (makes them available for client hosts to
mount using NFS). On the NFS client, these mounted directories look to users like part
of the client’s local file system. With MC/ServiceGuard NFS, the NFS server package
containing the exported file systems can move to a different node in the cluster in the
event of failure.
updated for
September 2003
MC/ServiceGuard NFS Toolkit version A.11.11.03 delivers an enhancement to support
File Lock Migration. MC/ServiceGuard NFS Toolkit was never designed to keep track of
which remote NFS clients were holding file locks with the filesystems associated with
highly available packages and transition these locks between servers during a failover
event. When enabled, the File Lock Migration enhancement removes this limitation.
Software Requirements
• Version A.11.11.01, A.11.11.02, and A.11.11.03 are supported only on HP-UX 11i v1.
• As of September 2003, MC/SG version A.11.15 must be installed, as
MC/ServiceGuard NFS Toolkit version A.11.11.03 has a dependency on MC/SG
A.11.15.
• To enable the File Lock Migration enhancement, the NFS General Release and
Performance Patch PHNE_26388 (or a superseding patch) must be installed.
