Verify the paths and status by issuing device-specific module
(DSM) commands (refer to the DSM user manual for the mul-
tipath management commands).
Validations During Router Insertion Process
Zone out the first direct path from the active zone set on the
Fibre Channel switch. The path status for the path belonging
to the zoned out controller port (for example, Port A) is shown
as failed in the DSM GUI on the host.
The newly-added path appears online and active on the host
in the DSM GUI. Depending upon the policy settings, part of
host IO may start flowing through the path presented by the
router. To verify, issue the show perf byte command on
the router to view the traffic flowing through the router ports.
The path status for the path belonging to the zoned-out control-
ler port (for example, Port B) is shown as failed in the DSM
GUI on the host. The entire host I/O now must flow through
the router. Verify that the show perf byte command shows
the I/O flowing through the router.
The host initiator port is seen as online and logged in on the
router CLI and HP MPX200 Manager. The newly-added path
appears online and active on the host in the DSM GUI. Depend-
ing upon the policy settings, part of the host I/O may start
flowing the new path presented by the router.
