verification Verify that more than one path exists by issuing the
scsimgr
lun_map
command. The
“
Last open or closed state
”
of the path
shows as either active or standby, based the LUN ownership and
array type.
Validations During Router Insertion Process
Removing first direct path from
controller port (for example,
Port A) Zone out the first direct path from the active zone set on the Fibre
Channel switch. The “Last open or closed state” of the path changes
to FAILED and the I/O will failover to the other active path.
Adding router path for the
removed controller port.(for
example, Port A ) 1. On the HP-UX host after zoning in the router presented target
controller (for example, Port A), issue the
ioscan
command.
2. Issue the
scsimgr lun_map
command and verify that the
newly-added path is shown as “Active/Standby.”
Removing second direct path
from controller port (for exam-
ple, Port B) Zone out the second direct path from the active zone set on the
Fibre Channel switch. The “Last open or closed state” of the path
changes to FAILED and the I/O will failover to the other active paths.
Because there are no direct paths, i/O will failover to the router pre-
sented path.
Adding router path for the
removed controller port.(for
example, Port B) 1. On the HP-UX host after zoning in the second router presented
target controller (for example, Port B), issue the
ioscan
com-
mand.
2. Issue the
scsimgr lun_map
command and verify that the
newly-added path is shown as “Active/Standby.”
