2. Enter the evaperf fn [short] command.
The fnames.conf file is created. Any friendly name information that exists for the management
servers running HP P6000 Command View and listed in the fnamehosts.conf file is
extracted from HP P6000 Command View and stored in the fnames.conf file, located in
INSTALLROOT.
NOTE: When the short option is used, the virtual disk properties (redundancy, preferred
path, and number of presentations) will not be retrieved and the output of the vd command
will have a hyphen (—) for these columns. To retrieve all the properties, the fn command
should be used without the short option.
Update the fnames.conf file when you make changes to the arrays. The fnames.conf file
must reside in the directory in which HP P6000 Performance Data Collector was installed.
Mapping worldwide names to friendly names
HP P6000 Performance Data Collector does not map the WWN for virtual disks to the HP P6000
Command View friendly name when the WWN value differs from the unique unit identifier (UUID).
The mismatch of WWN and UUID occurs if:
• The virtual disk has failed over in an HP P6000 Continuous Access environment.
• The WWN of the virtual disk is changed from the default WWN.
To match WWNs and UUIDs:
1. Open the fnames.conf file in a text editor.
2. Identify each virtual disk for which HP P6000 Performance Data Collector is not displaying a
friendly name.
3. Using the HP Storage System Scripting Utility, run the following command for each virtual
disk:
LS VDISK virtual disk name
All information about the virtual disk, including the WWN is displayed.
4. From the command output, copy the WWN for a virtual disk to the corresponding virtual disk
in the fnames.conf file, replacing all lowercase letters with uppercase.
5. Repeat Step 4 for each applicable virtual disk.
6. Save the fnames.conf file.
IMPORTANT: Do not run the command evaperf fn after completing these steps; otherwise,
you will have to repeat the steps.
Adding friendly names manually
You can create and maintain the fnames.conf file manually using a standard text editor.
Each line in the file contains a WWN that uniquely identifies an object and the friendly name of
the object. When reading this file, HP P6000 Performance Data Collector ignores blank lines and
lines that begin with a pound sign (#). The following is a listing from a manually created file:
