1 Metrocluster with EMC SRDF Version A.05.01 release
notes
Announcements
Metrocluster with EMC SRDF (Metrocluster/SRDF) is a member of Hewlett-Packard’s
family of high availability products for customers requiring integrated disaster recovery
solutions. Metrocluster/SRDF integrates EMC SRDF/Synchronous and
SRDF/Asynchronous with HP Serviceguard, allowing you to build clustering solutions
to failover applications and data across geographically separated data centers.
Metrocluster/SRDF provides automated reconfiguration of EMC Symmetrix arrays
using SRDF in a campus or a metropolitan Serviceguard cluster. Metrocluster/SRDF
can also be configured in a Continentalclusters environment, providing semi-automated,
push-button failover across unlimited distance.
Version A.05.01 is being released on HP-UX 11i v1 and 11i v2 with the following product
number:
• B6264BA - license and media
When introduced earlier, Metrocluster/SRDF A.05.01 was initially supported only
on HP-UX 11i v2. This release is an update to add support for Metrocluster/SRDF
A.05.01 on HP-UX 11i v1.
Integrating Metrocluster/SRDF with Serviceguard allows application packages to
failover:
• among local nodes that are attached to the same Symmetrix unit.
• between one system that is attached locally to a Symmetrix and another remote
node that is attached locally to another Symmetrix.
Since Metrocluster configurations may be complex to configure and maintain, it is
strongly recommended that you use Hewlett-Packard’s high availability consulting
services to ensure a smooth installation and rollout. Please contact your HP
representative to inquire about high availability consulting. In addition, you should
work with your HP representative to ensure that you have the latest firmware revisions
for disk drives, disk controllers, LAN controllers, and other hardware.
The patch PHSS_41308 supports Solutions Enabler Version 7.0 and later. This patch
is released only on HP-UX 11i v1 and cannot be applied to Metrocluster/SRDF installed
on HP-UX 11i v2. For information about new features provided with this patch, see
“New features in the patch PHSS_41308 on HP-UX 11i v1” (page 6).
What’s In this Version
Metrocluster/SRDF provides automated failover of Serviceguard packages on local and
remote EMC Symmetrix arrays that use SRDF.
