From the output display identify the device file listing that corresponds with the WWN of the vdisk in the DR group.
In the above sample listing there are eight device files that correspond to different paths of the same vdisk. Use any one of the device file names while creating a volume group, which is described in section, “Creating Volume Groups using Source Volumes for Secure Path v3.0D, v3.0E, and v3.0F”. The CV EVA display can be used to identify the WWN for a vdisk.
IMPORTANT: Secure Path is not supported on
Identifying Special Device Files for PVLinks Configuration
LVM PVlink feature can be used to handle path failovers to a storage device. The following describes how to identify device files for a Vdisk while setting up volume group using PVlinks. Use the RSM HV Mapper Tool or the HP StorageWorks EVAInfo tool to display the special device files that correspond to the WWN of the vdisk in the DR group.

See HostVolTable.txt for results.
The HostVolTable.txt output file provides a mapping of the devices file to vdisks for all the hosts that are RSM enabled. In addition, the tool displays the WWID of the vdisk and the storage system to which the vdisk belongs.
