From the output file, look for the special device file name that corresponds to the WWN identifier of the Vdisk in the DR group. Use the special device file while creating the volume group, which is described in section, “Creating Volume Groups using Source Volumes for Secure Path v3.0D, v3.0E, and v3.0F”. The EVA Command View for the WWN Identifier of the Vdisk is shown in Figure 37.
Figure 37 EVA Command View for the WWN Identifier
For more detailed information on setting up Command View EVA for configuring, managing, and monitoring your HP StorageWorks Enterprise Virtual Array Storage System, refer to the HP StorageWorks Command View EVA Getting Started Guide.
Identifying Special Device Files using Secure Path v3.0F
As described in the previous section, for each Vdisk in a DR group, use CV EVA to retrieve its own unique World Wide Name (WWN) identifier. When Secure Path v3.0F is used for path failover capabilities all the paths to the vdisk are visible. To identify the special device file names for the matching WWN identifier.
