Severity

ERROR

Description

This message occurs when the cable attached to SAS (Serial Attached SCSI) adapter port is functioning in a degraded mode.

Corrective Action

This condition implies one or more of the lanes in a 4-wide cable is fuctioning at a less-than-optimal speed, or is not functioning and has been disabled. The port will continue functioning but in a degraded, lower-performing mode. The cable should be replaced at some point in the future.

Syslog Message

Cable attached to SAS port "%s" is functioning in a degraded mode.

Parameters

adapterName (STRING): The name of the associated SAS host bus adapter.

sas.cable.linkratelow

Severity

NOTICE

Description

This message occurs when the expander or cable attached to the SAS (serial-attached SCSI) host bus adapter port is functioning at a speed lower than its specification. This could happen because the HBA is connected to an IOM that supports a lower speed, or because of a speed degradation due to a faulty component, or because of a lower common shelf stack speed.

Corrective Action

(None).

Syslog Message

Expander or cable attached to SAS port %s is operating at %s, which is lower than expected.

Parameters

adapterName (STRING): Name of the associated SAS host bus adapter.
currentSpeed (STRING): Current link rate for SAS host bus adapter, cable, and IOM expander.
