Mapping remote command devices to each site

Procedure

1. Configure LU paths between ports at each site.

For more information about setting up LU path, see the Provisioning Guide for Virtual Storage Platform Gx00 and Fx00 Models .

2. Set up command devices at all sites.

For more information about command device settings, see the Provisioning Guide for Virtual Storage Platform Gx00 and Fx00 Models .

3. On each site, map a command device to a device on one of the other sites.

For more information about mapping the remote command devices, see the Universal Volume Manager User Guide .

Thus:

• Each site must have two command devices mapped via two different ports to the other two sites.

• Each site must also have two remote command devices mapped-to via different ports from the other two sites.

The following illustration shows this command/remote command device configuration with port configuration.

For the command device's logical device, the attribute in the table is displayed as Command Device in the Logical Device window. Likewise, for the remote command device's logical device, the attribute in the table is displayed as Remote Command Device in the Logical Device window. For more information about the Logical Device window, see the Provisioning Guide for Virtual Storage Platform Gx00 and Fx00 Models .

After mapping the remote command devices is completed, mirror IDs must be assigned to the remote command devices.
