Reconfigure 
Applications to Use 
emcpower Devices
If you plan to use native names (recommended) with a volume 
manager, file system application, or database manager, you can 
ignore this section. PowerPath load balancing and failover 
functionality are enabled with no further action on your part.
However, if you plan to use emcpower devices with a third-party 
volume manager, file system application, or database manager, 
you must reconfigure the application to use emcpower devices. 
Refer to Installing and Configuring Emcpower Devices With Solaris 
Applications
, which is available on the Powerlink website 
(
).
For more information on native and pseudo names, refer to Device 
Naming
 on page 5-5.
 If you are unsure whether to use emcpower or 
native names, contact the EMC Customer Support Center.
