A–Troubleshooting
ISR654606-00 A A-3
The MPX200 does not show masked LUNs,
and instead shows LUN 0 only with offline sta-
tus for an EMC CX array.
Verify that the MPX200 port is registered with the stor-
age 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 HP StorageWorks mpx Manager GUI, click
Refresh two or three times.
The MPX200 tries to start a scheduled job and
shows a job in Pending state instead of Run-
ning state.
Make sure that the LUN state is online for both the
source and destination LUNs. Check if the zoning con-
figuration is valid and that the arrays are shown in an
online state. If the array state is online and the LUN
state is offline, 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been replaced by another LUN at the time of starting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 asso-
ciated job will have to be deleted. For more informa-
tion, see “Reconfiguring LUNs on a Storage Array” on
page 8-1.
