Verify that the MPX200 port is registered with the storage
system through the same storage controller port through
which it is trying to access the LUNs. If the MPX200 ports
are registered with SPA-0 port, and SPA-1 port is zoned
with the MPX200 ports on the switch, the MPX200 will
not see any of the assigned LUNs.
On presenting a data LUN for the first time, the router
considers it to be an array reconfiguration scenario,
where the data LUN replaces the controller LUN. To see
the correct LUN details, perform either of these options:
• In the CLI, issue the show luninfo command two
or three times.
• In the mpx Manager GUI, click Refresh two or three
times.
The MPX200 does not show masked LUNs, and
instead shows LUN 0 only with offline status for an
EMC CX array.
Make sure that the LUN state is online for both the source
and destination LUNs. Check whether the zoning config-
uration is valid and that the arrays are shown in an online
state. If the array state is online and the LUN state is off-
line, make sure that the LUN presented to the MPX200
at the time of configuring the job has not been replaced
by another LUN at the time of starting the job. This is a
case of reconfiguration and the associated job will have
to be deleted. For more information, see “Reconfiguring
LUNs on a storage array” on page 354.
The MPX200 tries to start a scheduled job and
shows a job in Pending state instead of Running
state.
