How to Force an FCoE Port Reinitialization

Use the steps below when an FCoE port needs to be reinitialized. You might need to force an FCoE port reinitialization when new devices are added to an FC SAN or because of some misbehaving device on the SAN. In many cases, this operation can resolve problems in an FC-SAN.

When this command issued on the target port side, the target port is reset. When this command is issued from the host port side, the host port is reset.

When an FC switch is connected, other FC ports in the SAN get a remote state change notification (RSCN). Furthermore, other initiators will always rediscover the port after this operation, and the FC login session will be established or reused. This command is disruptive to I/Os, but I/Os continue. This command is not destructive because it does not cause any data loss.

1. Become an administrator.
2. Force a link that is connected to a port to reinitialize.

   For example:

   # fcadm force-lip 200000144fc2d508
