Creating VDISKs and DR groups using HP P6000 command view
The P6000 Command View is a web-based tool to configure, manage, and monitor virtual disks
and DR groups as shown in Figure 2 (page 16).

For more information on setting up HP P6000 Command View for configuring, managing, and
monitoring HP P6000/EVA Storage System , see HP P6000 Command View User Guide available
at http://www.hp.com/support/manuals -> storage-> Storage Software-> Storage Device
Management Software-> HP StorageWorks HP P6000 Command View Software.
Using the Command View (CV) web user interface create VDISKS, create DR GROUP using the
VDISKS and present those VDISKS to the connected host. When a DR group is created set the
destination host access field as Read only using Command View GUI.
NOTE: In the Metrocluster Continuous Access EVA environment, it is required that the destination
volume access mode of the DR group be set to Read only mode.
In some earlier Command View software versions, when a DR group is created, only the source
volume (primary volume) is visible and accessible with Read/Write mode. The destination volume
(secondary volume) by default is not visible and accessible to its local hosts. The destination volume
access mode needs to be changed to Read only mode before the DR group can be used and the
destination volumes need to be presented to its local hosts.
For users who are not familiar with the Storage System Scripting Utlity (SSSU) commands, an input
sample file is provided in the following location:/opt/cmcluster/toolkit/SGCAEVA/
Samples/sssu_sample_input.
The contents of this file are listed below. In this sample file, DC-1 is the name of the source array.
