devices:

 

 

a. Configure any missing logical devices. Enter:

 

 

 

powercf -q

 

 

 

powermt config

 

 

b. Rerun powermt display dev=all to confirm that

 

 

 

These logical devices are configured as emcpower devices.

 

 

 

– The correct failover and load balancing policy is set. (For

 

 

 

information about powermt and load-balancing policies,

 

 

 

see the PowerPath Product Guide.)

 

 

 

 

 

 

 

 

If you plan to enable R1/R2 boot disk failover, see R1/R2 Boot

 

 

 

Failover Support on page 5-4.

 

 

 

 

 

 

 

c. If the failover and load balancing policy is not set correctly,

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

 

 

(http://powerlink.emc.com).

 

 

For more information on native and pseudo names, refer to Device

native names, contact the EMC Customer Support Center.
