HP StorageWorks Data Replication Manager HSG80 ACS Version 8.7P Configuration Guide (AA-RPHZF-TE, March 2004)

Configuring a Standard Data Replication Manager Solution
58 Data Replication Manager HSG80 ACS Version 8.7P Configuration Guide
Introduction
The disaster tolerant (DT) configuration that supports DRM requires two HSG80 Array
Controller subsystems—one at an initiator site and one at a target site.
Tip: Because of the complexity of the configuration process, it is a good idea to have all DRM
documentation available at both sites to eliminate confusion and minimize the risk of error. Follow
the steps precisely in the order provided in this document.
Figure 16 shows a basic DRM configuration; it is referenced throughout this chapter.

Restrictions
It is important to understand the operating restrictions before configuring your DRM solution.
Table 6 lists points to consider before proceeding to the configuration process.

Table 6: Restrictions and Requirements
Restriction or Requirement Comments
Two HSG80 controller pairs are required. All controllers must run ACS V8.7P. HSG60
controller pairs are not supported.
Four Fibre Channel switches are required.
(The entry-level DRM configurations
introduced in Chapter 5 are exceptions to
this restriction).
These switches provide two separate fabrics
connecting controllers at the initiator and target
sites.
HSG80 controllers can be configured for
Fibre Channel switched protocol and SCSI-2
or SCSI-3 protocol.
HP OpenVMS host operating systems and
adapters must support Fibre Channel switched
protocol and SCSI-3 protocol
Except OpenVMS, the host operating systems
and adapters must support Fibre Channel
switched protocol and SCSI-2 or SCSI-3 protocol.
Mirrored write-back cache must be enabled. Requires 512 MB of cache per controller (256
MB effective capacity when mirrored).
