MC/ServiceGuard NFS Toolkit (updated for September 2001)
Major Updates for
September 2001:
• MC/ServiceGuard NFS Toolkit can now monitor TCP services, when NFS over TCP is
enabled.
• MC/ServiceGuard NFS Toolkit versions A.11.00.04 and A.11.11.02 can use the same
NFS package control script, configuration file, and monitor script.
Overview
Multi-Computer/ServiceGuard Network File Server (MC/ServiceGuard NFS) Toolkit
Version A.11.11 uses MC/ServiceGuard to set up highly available NFS servers. NFS
servers are hosts that “export” their local directories and make them available for client
hosts for mounting. On the NFS client, these mounted directories look like part of the
client’s local file system.
MC/ServiceGuard NFS Toolkit is a set of configuration files and control scripts which
can be customized to user specific needs.
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.
