with a license key

is restricted to basic failover.

 

 

View the LUNs available to the server using the following PowerPath

 

 

command:

 

 

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 a pseudo device that represents the chosen LUN.

 

 

Start I/O to the LUN.

 

 

Identify the HBA sending I/O to the 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 path(s) becomes “dead.”

 

 

• I/O continues to the remaining path(s) to the LUN, indicating that the

 

 

failover path was successful, and PowerPath is working properly.

 

 

Reconnect the cable that you disconnected from the HBA.

 

 

If you 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.
