Dynamic Root Disk |
 |
Dynamic Root Disk is an HP-UX system administration tool set
used to clone an HP-UX system image to a disk other than that from
which the system is currently booted, for puroses of software maintenance
and recovery. In this way, you can install software and patches to
a clone of your current system without affecting the running
system. Then, when an opportunity to reboot the system
is available, the patched or updated clone can be booted. This reduces
system downtime to just the time it takes to reboot to the clone.
Also, if necessary, the changes can be quickly backed out by simply
rebooting to the original clone.
High Availability Monitors |
|
High availability monitors allow you to check
up on your system’s resources and to be informed if problems
develop. They can be used in conjunction with Serviceguard. Monitors
are available for disk resources, cluster resources, network interfaces,
system resources, and database resources. When a monitor detects a
problem, an alert is sent, allowing an operator or administrator to
correct the problem.

MetroCluster |
|
MetroCluster is a Hewlett-Packard high availability
product for Serviceguard customers requiring integrated disaster recovery
solutions. MetroCluster provides automated failover of ServiceGuard
packages on local and remote high availability disk arrays. Integrating
MetroCluster with Serviceguard allows application packages to fail
over:
Between one system that
is attached locally to an array frame and another remote node that
is attached locally to another array frame.
Among local nodes that
are attached to the same array.
Two versions of MetroCluster are available:
MetroCluster with Continuous
Access XP provides a special package-control script template to implement
physical replication between HP SureStore XP256 or XP512 disk arrays.
MetroCluster with EMC
SRDF provides a special package-control script template to implement
physical replication between EMC Symmetrix disk arrays.

Continental Clusters |
|
Continental Clusters is a Hewlett-Packard high
availability solution that provides disaster tolerant clustering over
long distances. Continental Clusters employs semi-automatic failover
of Serviceguard packages from a primary cluster to a recovery cluster
following a cluster event that indicates serious disruption of service
on the primary cluster.
The product consists of a set of configuration
tools, a monitor that sends notification of cluster-down events, and
a command that moves packages from one cluster to another. In addition,
Continental Clusters includes the following components:
Cluster Object Manager,
which provides the ability to query ServiceGuard cluster status.
A special package control
script template to implement physical data replication between HP
SureStore XP256 or HP512 disk arrays.
A special package control
script template to implement physical data replication between EMC
Symmetrix disk arrays.

HP ServiceControl |
|
HP ServiceControl is a system management environment
including high capacity HP HyperPlex clusters. It provides a consolidated
point for managing your workload, applications, and resources on your
system from a single management station. High availability products,
such as Serviceguard and HA Monitors, reside physically on the HyperPlex
cluster nodes.
HP ServiceControl organizes nodes into HyperPlex
clusters. Within these clusters, Serviceguard minimizes and eliminates
application downtime by
Protecting mission-critical
applications from a variety of hardware and software failures by monitoring
the health of each node.
Balancing the workload
on a system by responding quickly to changes and workload demands.
