Fibre Channel over Ethernet host-link problems

Problems attaching to the Fibre Channel over Ethernet (FCoE) hosts might be related to the network, the system, or the host.

Before you begin

If error code 705 on node is displayed, this code means the Fibre Channel (FC) I/O port is inactive. Fibre Channel over Ethernet (FCoE) uses Fibre Channel (FC) as a protocol and Ethernet as an inter-connect.
Note: Concerning a Fibre Channel over Ethernet (FCoE) enabled port: either the Fibre Channel forwarder (FCF) is not seen, or the Fibre Channel over Ethernet (FCoE) feature is not configured on switch.
  • Verify that the Fibre Channel over Ethernet (FCoE) feature is enabled on the Fibre Channel forwarder (FCF).
  • Verify the remote port (switch port) properties on the Fibre Channel forwarder (FCF).
If you connect the host through a Converged Enhanced Ethernet (CEE) Switch:
  • Test your connectivity between the host and Converged Enhanced Ethernet (CEE) Switch.
  • Ask the Ethernet network administrator to check the firewall and router settings to verify the settings.

Run lsfabric, and verify that the host is seen as a remote port in the output. If the host is not seen, in order:

  • Verify that system and host get a Fibre Channel ID (FCID) on the Fibre Channel forwarder (FCF). If unable to verify, check the VLAN configuration.
  • Verify that system and host port are part of a zone and that zone is in force.
  • Verify that the volumes are mapped to host and are online. For more information, see lshostvdiskmap and lsvdisk in the description in the IBM® Knowledge Center.

What to do next

If the problem is not resolved, verify the state of the host adapter.

  • Unload and load the device driver.
  • Use the operating system utilities (for example, Windows Device Manager) to verify that the device driver is installed, loaded, and operating correctly.
