scsitarget.fct.linkError

Severity

ERROR

Description

This message occurs when a Fibre Channel (FC) Host Bus Adapter (HBA) encounters a physical layer issue. This might result in the frame being dropped. The following are examples of protocol errors that result in this message: - Bad start of frame (SOF) - Bad end of frame (EOF) - CRC error - Running disparity error - Link Reset primitive detection

Corrective Action

Recurring instances of this message indicate a physical layer issue. Perform the following recovery actions: - Verify that the overall SAN fabric is healthy. - Verify that the SFP is healthy at both endpoints, replace if necessary. - Clean or replace the cables. Contact technical support with the code and status information for further analysis.

Syslog Message

scsitarget.fct.loginfailed

Severity

ERROR

Description

This message occurs when the SLI Fibre Channel target driver encounters a FDISC or FLOGI failure. The failure can cause the FC target port or the LIF to be operationally down.

Corrective Action

Contact technical support for further analysis.

scsitarget.fct.npivErr

Severity

ERROR

Description

This message occurs when the Fibre Channel (FC) fabric does not have NPIV (N Port ID Virtualization) enabled.

Corrective Action

Enable NPIV on the FC fabric for the FC LIF (logical interface) to come online. The fabric port related to the FC LIF should be disabled and then reenabled after NPIV is enabled. Use the "network interface" command to mark the operational status of the LIF as "up".

Syslog Message

NPIV is disabled on the fabric %s port %s. The target HBA resides at host %s at port %s.

Parameters

switch_name (STRING): FC fabric name.
switch_port_num (STRING): Fabric port number where NPIV is disabled.

scsitarget.fct.offlineStart

Severity

NOTICE

Description

scsitarget.fct.onlining

Severity

NOTICE

Description

This message occurs when the FCT adapter is online.

scsitarget.fct.pingErr

Severity

ERROR

Description

This message occurs when the ELS_ECHO reply does not match the ELS_ECHO request issued by the 'fcp ping' CLI command. This means that the 'fcp ping' command failed the signal quality tests specified in the Methodologies for Signal Quality Specification (MSQS).

Corrective Action

Check the applicable section of MSQS (http://www.t11.org/ftp/t11/pub/fc/msqs/10-314v3.pdf): if a default payload was specified in the 'fcp ping' command and the platform is 8GFC or lower then the JSPAT (scrambled jitter pattern) test failed. Check the MSQS section 2.1 for a list of tests that JSPAT verifies. If the platform is 10GFC or higher and a default payload was specified, then an OMA (Optical Modulation Amplitude) or VMA (Voltage Modulation Amplitude) test failed. Check the MSQS section 2.2.1 for an explanation of these methods.

Syslog Message

FC ping failed because of a mismatch between request and response payloads. The request payload is %s and the response payload is %s at index %d. The link rate of the port is %d.

Parameters

req_payload (STRING): First mismatched character of ELS ECHO request payload.
res_payload (STRING): First mismatched character of ELS ECHO response payload.
index (INT): Index of the first mismatch between the ECHO request and response payloads.
link_rate (INT): Link rate of the Fibre Channel (FC) port.

scsitarget.fct.port.full

Severity

NOTICE

Description

This message occurs when the number of outstanding commands on a physical FC target port exceeds the supported limit on that port.

Corrective Action

To recover from this condition, evaluate the host fan-in on the port, and then take one of the following actions: - Reduce the number of hosts that are logging in to this port. - Reduce the number of LUs being accessed by the hosts logging in to this port. - Reduce the host command queue depth. Monitor the queue_full counter on the fcp_port CM object, and make sure that it is not increasing. Example: statistics show -object fcp_port -counter queue_full -instance port.portname -raw Monitor and verify that the threshold counter is also not increasing. Example: statistics show -object fcp_port -counter threshold_full -instance port.portname -raw

Syslog Message

FC target port %s has %d outstanding commands, which exceeds the maximum number of commands %d that can be supported by this port.

Parameters

portname (STRING): Port name on which the outstanding commands exceeded the supported limit.
active_commands (INT): Number of outstanding commands on the port.
max_commands (INT): Number of maximum commands supported on the port.

scsitarget.fct.port.offline

Severity

ERROR

Description

Monitor the threshold_full counter on the fcp_port CM object, and make sure that it is not increasing. Example: statistics show -object fcp_port -counter threshold_full -instance port.portname -raw

Syslog Message

FC target port %s has %d outstanding commands, which exceeds the threshold %d for this port.
