NonStop Clusters Verification Utility
NonStop Clusters Verification Utility (NSCVU) validates Compaq ProLiant
Clusters for SCO UnixWare 7 and their components. This utility reports
information about the configuration of a newly installed cluster, providing
cluster-wide information as well as node-specific information and volume
information.
The Quick Install procedure automatically installs the NSCVU. On the
Management CD, the package that provides this support is
nscvu
and is part of
the Compaq Management Agents and Tools for Servers for SCO UnixWare 7
NonStop Clusters portion of the CD. For more information, see the description
of the Quick Install CDs in Chapter 1, “Clustering Overview,” of this guide.
UPS-Initiated Shutdown
The Quick Install procedure automatically installs the UPS software. On the
Management CD, the package that provides this support is
nscups
and is part of
the Compaq Management Agents and Tools for Servers for SCO UnixWare 7
NonStop Clusters portion of the CD.
Use UPSs with Compaq ProLiant clusters to minimize system downtime in the
event of power loss. Cable the UPSs to enable the cluster to be cleanly shut
down before the UPS battery backup is exhausted. The UPS-initiated
shutdown can minimize data loss and improve cluster reboot speed when
power returns.
A monitoring process running within the cluster provides the UPS-initiated
shutdown. A simple configuration file controls this monitoring process.
