sas.device.timeout

Severity

ERROR

Description

All outstanding commands to the specified device have not completed within the allotted time. As part of the standard error handling sequence managed by the Data ONTAP SAS driver, all commands to the device will be aborted and reissued.

Corrective Action

Device level timeouts are a common indication of a SAS link stability problem. In some cases the link is operating normally and the specified device is having trouble processing I/O requests in a timely manner. In such cases the specified device should be evaluated for possible replacement. Quite often the problem results from the partial failure of a component involved in the SAS transport. Common things to check include complete seating of drive carriers in enclosure bays, properly secured cable connections, IOM seating, and crimped or otherwise damaged cables.

Syslog Message

Adapter %s encountered a device timeout on %s device %s.

Parameters

adapterName (STRING): The name of the associated SAS host bus adapter.
deviceType (STRING): The device type.
deviceName (STRING): The name of the SAS device.
