Fewer Fibre Channel ports operational.
Explanation: A Fibre Channel port that was
previously operational is no longer operational. The
physical link is down.
This node error does not, in itself, stop the node
canister becoming active in the system. However, the
Fibre Channel network might be being used to
communicate between the node canisters in a clustered
system. Therefore, it is possible that this node error
indicates the reason why the critical node error 550 A
cluster cannot be formed because of a lack of
cluster resources is reported on the node canister.
Data:
Three numeric values are listed:
v The ID of the first unexpected inactive port. This ID
is a decimal number.
v The ports that are expected to be active, which is a
hexadecimal number. Each bit position represents a
port, with the least significant bit representing port 1.
The bit is 1 if the port is expected to be active.
v The ports that are actually active, which is a
hexadecimal number. Each bit position represents a
port, with the least significant bit representing port 1.
The bit is 1 if the port is active.
User response:
1. If possible, use the management GUI to run the
recommended actions for the associated service
error code.
2. Possibilities:
v If the port has been intentionally disconnected,
use the management GUI recommended action
for the service error code and acknowledge the
intended change.
v Check that the Fibre Channel cable is connected
at both ends and is not damaged. If necessary,
replace the cable.
v Check the switch port or other device that the
cable is connected to is powered and enabled in a
compatible mode. Rectify any issue. The device
service interface might indicate the issue.
v Use the remove and replace procedures to replace
the SFP transceiver in the Storwize V7000 and the
SFP transceiver in the connected switch or device.
v As the adapter is located on the system board,
replace the node canister using the remove and
replace procedures.
Possible Cause-FRUs or other cause:
v Fibre Channel cable
v SFP transceiver
v Node canister

Fewer Fibre Channel I/O ports
operational.
Explanation: One or more Fibre Channel I/O ports
that have previously been active are now inactive. This
situation has continued for one minute.
A Fibre Channel I/O port might be established on
either a Fibre Channel platform port or an Ethernet
platform port using FCoE. This error is expected if the
associated Fibre Channel or Ethernet port is not
operational.
Data:
Three numeric values are listed:
v The ID of the first unexpected inactive port. This ID
is a decimal number.
v The ports that are expected to be active, which is a
hexadecimal number. Each bit position represents a
port, with the least significant bit representing port 1.
The bit is 1 if the port is expected to be active.
v The ports that are actually active, which is a
hexadecimal number. Each bit position represents a
port, with the least significant bit representing port 1.
The bit is 1 if the port is active.
User response:
1. If possible, use the management GUI to run the
recommended actions for the associated service
error code.
2. Follow the procedure for mapping I/O ports to
platform ports to determine which platform port is
providing this I/O port.
3. Check for any 704 (Fibre channel platform port
not operational) or 724 (Ethernet platform port
not operational) node errors reported for the
platform port.
4. Possibilities:
v If the port has been intentionally disconnected,
use the management GUI recommended action
for the service error code and acknowledge the
intended change.
v Resolve the 704 or 724 error.
v If this is an FCoE connection, use the information
the view gives about the Fibre Channel forwarder
(FCF) to troubleshoot the connection between the
port and the FCF.
Possible Cause-FRUs or other cause:
v None

Fibre Channel clustered system path
failure.
Explanation: One or more Fibre Channel (FC)
input/output (I/O) ports that have previously been
able to see all required online node canisters can no
longer see them. This situation has continued for 5
minutes. This error is not reported unless a node is
