❑
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 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
path failover was successful, and PowerPath is working properly.
