MC/ServiceGuard is used to create high-availability clusters of HP 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.

December 2001
• MC/ServiceGuard NFS Toolkit versions A.11.00.05 and A.11.11.02 are major
releases. Both of these versions have dependencies on MC/SG A.11.13 that provide
the integrated solution for multiple MC/ServiceGuard partner software working
together under the new MC/SG framework. MC/SG NFS Toolkit has been
re-architected to fit under the new framework.
• NFS-related control functions and variables have been extracted from
MC/ServiceGuard package control script to a separate NFS specific control script,
hanfs.sh. When the MC/ServiceGuard package is started, it will check for this
script under the package directory, and if it exists, will invoke NFS control script.
• An easy troubleshooting mechanism has been provided. Customers can easily
identify if a problem resides in MC/SG NFS Toolkit from the MC/SG package log file.
• MC/ServiceGuard NFS Toolkit A.11.11.02 supports VxVM as an alternative disk
storage management technology.

NFS package control script, configuration file, and monitor script.
