E Identifying special device file name for Vdisk in DR group
Using secure path V3.0D or V3.0E
For each Vdisk in a DR group use HP P6000 CV to retrieve its own unique World Wide Name
(WWN) identifier. To identify the special device file name for the matching WWN identifier in a
single clustered node use:
# spmgr display
The following is a sample output after running the spmgr command:

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 HP P6000 Command View to identify the WWN for a Vdisk
Using secure path v3.0F
As described in the previous section, for each Vdisk in a DR group, use HP P6000 CV to retrieve
its own unique 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.
