However, before setting up MC/ServiceGuard NFS, you should set up the
MC/ServiceGuard cluster. For instructions see Managing
MC/ServiceGuard available on the HP-UX 11i Instant Information CD
and on the web at:
http://docs.hp.com/
MC/ServiceGuard is used to create high availability clusters of HP 9000
servers. Computer systems with high availability clusters allow
applications to continue in spite of a hardware or software failure. Such
systems protect users from software failures as well as from failure of a
system processing unit (SPU) or local area network (LAN) component. In
the event that one component fails, the redundant component takes over
and MC/ServiceGuard coordinates the transfer between components.
With MC/ServiceGuard NFS Toolkit, the NFS server package containing
the exported file systems moves to a different node in the cluster in event
of a failure. After MC/ServiceGuard starts the NFS package on the
adoptive node, the NFS file systems are re-exported from the adoptive
node with minimum disruption of service to users. The client side
“hangs” until the NFS server package comes up on the adoptive node.
When the service returns, the user can continue access to the file. You do
not need to restart the client.
File locks are not preserved when a MC/ServiceGuard NFS package
moves over to another node.
For use and configuration information, see Managing Highly Available
NFS (B5125-90001) available on the HP-UX 11i Instant Information CD
