Procedure: FCoE host-link
About this task
If you are having problems attaching to the FCoE hosts, your problem might be
related to the network, the Storwize V7000 system, or the host.
Procedure
1. If you are seeing error code 705 on the node, this means Fibre Channel I/O
port is inactive. Note that FCoE uses Fibre Channel as a protocol and an
Ethernet as an interconnect. If you are dealing with an FCoE enabled port that
means either the Fibre Channel Forwarder (FCF) is not seen or the FCoE
feature is not configured on the switch:
a.
Check that the FCoE feature is enabled on the FCF.
b. Check the remote port (switch port) properties on the FCF.
2.
If you connecting the host through a Converged Enhanced Ethernet (CEE)
switch, for network problems, you can attempt any of the following actions:
a. Test your connectivity between the host and CEE switch.
b. Ask the Ethernet network administrator to check the firewall and router
settings.
3. Please run svcinfo lsfabric and check that the host is seen as a remote port in
the output. If not, then do the following tasks in order:
a. Verify that Storwize V7000 and host get an fcid on FCF. If not, check the
VLAN configuration.
b.
Verify that Storwize V7000 and host port are part of a zone and that zone is
currently in force.
c. Verify the volumes are mapped to the host and that they are online. See
lshostvdiskmap and lsvdisk in the CLI configuration guide for more
information.
4. If you still have FCoE problems, you can attempt the following action:
