You should set your adapter target port speed to match the speed of the device to which it connects, instead of using autonegotiation. A port that is set to autonegotiation can take longer time to reconnect after a takeover/giveback or other interruption.
All LIFs that use this adapter as their home port must be offline.
Because this task encompasses all storage virtual machines (SVMs) and all LIFs in a cluster, you must use the -home-port
and -home-lif
parameters to limit the scope of this operation. If you do not use these parameters, the operation applies to all LIFs in the cluster, which might not be desirable.
-
Take all of the LIFs on this adapter offline:
network interface modify -vserver * -lif * { -home-node node1 -home-port 0c } -status-admin down
-
Take the adapter offline:
network fcp adapter modify -node node1 -adapter 0c -state down
If the adapter does not go offline, you can also remove the cable from the appropriate adapter port on the system.
-
Determine the maximum speed for the port adapter:
fcp adapter show -instance
You cannot modify the adapter speed beyond the maximum speed.
-
Change the adapter speed:
network fcp adapter modify -node node1 -adapter 0c -speed 16
-
Bring the adapter online:
network fcp adapter modify -node node1 -adapter 0c -state up
-
Bring all of the LIFs on the adapter online:
network interface modify -vserver * -lif * { -home-node node1 -home-port 0c } -status-admin up
