Fibre Channel over Ethernet host-link problems
Problems attaching to the Fibre Channel over Ethernet hosts might be related to the network, the SAN Volume Controller system, or the host.
Before you begin
If error code 705 on node is displayed, this code means the FC I/O port is inactive. Fibre
Channel over Ethernet uses Fibre Channel as a protocol and Ethernet as an
inter-connect.
Note: Concerning a Fibre Channel over Ethernet enabled port: either the Fibre Channel
forwarder (FCF) is not seen, or the Fibre Channel over Ethernet feature is not configured on
switch.
- Verify that the Fibre Channel over Ethernet feature is enabled on the FCF.
- Verify the remote port (switch port) properties on the FCF.
If you connect the host through a Converged Enhanced Ethernet (CEE) Switch:
- Test your connectivity between the host and CEE Switch.
- Ask the Ethernet network administrator to check the firewall and router 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 SAN Volume Controller and host get a Fibre Channel ID (FCID) on the FCF. If unable to verify, check the VLAN configuration.
- Verify that SAN Volume Controller and host port are part of a zone and that zone is currently 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 SAN Volume Controller Information 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.
