Procedure: Fcoe Host-Linking; Procedure: Removing And Replacing The Lid Of A Storwize V7000 Gen2 Node Canister - IBM Storwize V7000 Unified Problem Determination Manual

About this task
A failure has indicated that the node software is damaged and must be reinstalled.
Procedure
1. Log on to the service assistant. See "Accessing the service assistant" on page
204 for details.
2. Ensure that the node you want to reinstall the code on is the current node.
3. Select Rescue from another node.

Procedure: FCoE host-linking

About this task
If you are having problems attaching to the FCoE hosts, your problem might be
related to the network, the Storwize V7000 Unified system, or the host.
Procedure
1. If you are seeing error code 705 on the node, this means that the 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, this
means that 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 are 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. 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 Unified and host get an fcid on FCF. If not,
check the VLAN configuration.
b. Verify that Storwize V7000 Unified 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:
a. Verify that the host adapter is in good state. You can unload and load the
device driver and see the operating system utilities to verify that the device
driver is installed, loaded, and operating correctly.
