Zoning Hosts and HSG80 Subsystems Between Sites
In a DRM configuration, the initiator hosts are zoned so that they do not have access to the
target controllers; the target hosts are zoned so that they do not have access to the initiator
controllers.
There are circumstances, however, when the hosts at one site do require access to HSG80
controller pairs at both sites. This could occur when you are running scripts, OpenVMS
host-based shadowing, or stretch clusters. If that is the case, go to the section titled “Zoning to
Allow Host Access Between Sites,” on page 208.
Zoning a DRM Configuration
This section provides zoning examples for both homogeneous and heterogeneous
configurations.
DRM Homogeneous Configuration
The Fibre Channel fabric can be customized for zoning in numerous ways. The DRM uses for
zoning include:
■ Creating fabric functional areas by separating test or maintenance areas from production
areas
■ Designating closed user groups by including certain zone devices for exclusive use by
zone members
■ Simplifying resource utilization by logically consolidating equipment for convenience
■ Facilitating time-sensitive functions by creating a temporary zone to back up a set of
devices that are members of other zones
■ Securing fabric areas by providing another level of software security to control port level
access
■ Separating operating system types and applications to control access to resources
This section provides examples of zoning a DRM configuration. The examples begin with the
configuration of a DRM homogeneous environment. Additional examples illustrate creating a
DRM heterogeneous environment from the homogeneous environment. The examples are
from a Telnet session on a Fibre Channel storage switch that is case sensitive. Other switches
may not be case sensitive.
Figure 32 shows a simplified DRM configuration that consists of six zones. For this example,
the zones are designated Green Zone_Top and Green Zone_Bottom for the initiator site; Blue
Zone_Top and Blue Zone_Bottom for the target site; and Red Zone_Top and Red
Zone_Bottom, which contain the remote copy sets or paths.
Note: Zones are given color names in this document only as examples. You should choose names
that are meaningful for your environment.
