MC/ServiceGuard NFS Toolkit
MC/ServiceGuard NFS is a toolkit that includes the configuration files and control
scripts and allows you to use MC/ServiceGuard to set up highly available NFS servers.
Highly available systems protect users from failure of a system processing unit (SPU) or
local area network components. In the event that one component fails, the redundant
component takes over and MC/ServiceGuard coordinates the transfer between
components.
MC/ServiceGuard NFS Toolkit A.11.23.01 is functionally equivalent to version
A.11.11.02 and has dependencies on MC/ServiceGuard A.11.13 or later.
(MC/ServiceGuard A.11.15 is delivered with HP-UX 11i v2.) MC/ServiceGuard (MC/SG)
A.11.15 provides the integrated solution for multiple MC/ServiceGuard partner software
working together under the new MC/SG framework. (For more information about
MC/ServiceGuard A.11.15, see “MC/ServiceGuard” on page 90.)
Summary of Change
The MC/ServiceGuard NFS Toolkit A.11.23.01 provides the following important new
features:
• Product re-architected to provide a smoothly integrated solution with other
MC/ServiceGuard partner software.
• NFS-related control functions and variables have been extracted from the
MC/ServiceGuard package control script to a separate NFS specific control script,
hanfs.sh. When the MC/ServiceGuard package is started, MC/ServiceGuard will
check if this NFS-specific control script exists under the package directory. If so, it
will invoke the NFS control script.
• Dependent on MC/ServiceGuard version A.11.13 and above.
• Support for VERITAS Volume Manager (VxVM) 3.5. The VERITAS Volume Manager
for HP-UX is available as an alternative volume manager for online data and storage
management.

• An easy troubleshooting mechanism provided. It is easier for customers to identify if
a problem resides in MC/ServiceGuard NFS Toolkit from the MC/ServiceGuard
package log file.
• Support for NFS high availability over NFS TCP and NFS UDP.
