		❑ View the LUNs available to the server using the following PowerPath	PowerPath product
		command:	guide
		powermt display dev=all class=clariion
		❑ Choose one available LUN to receive I/O for the test.
		❑ View the paths to the chosen LUN using the following PowerPath
		command:
		powermt display dev=x every=2
		where x is pseudo device that represents the chosen LUN.
		❑ Start I/O to the LUN.
		❑ Identify the HBA sending I/O to LUN by viewing the output of the powermt
		display dev=x every=2 command, and disconnect the cable to that HBA.
		❑ View the output of the powermt display dev=x every=2 command, and
		verify that
		• The state of the uncabled paths becomes “dead.”
		• I/O continues to the remaining path(s) to the LUN, indicating that the
		path failover was successful, and PowerPath is working properly.
		❑ Reconnect the cable that you disconnected from the HBA.
		❑ If you did not follow the above steps exactly and caused any LUNs to
		trespass, restore the LUNs to their original SP with the following PowerPath
		command:
		powermt restore

You are now ready to set up any optional software, such as SnapView or MirrorView, on the storage system.
