Switch chip ports and their connectors can be configured to automatically disable should their links exhibit high error rates or sub-optimal link speed or width. You use the autodisable command to add the connectors to the autodisable list, which has two parts; one for connectors whose links fail from high error rates, and another for connectors whose links fail from suboptimal link speed or width. A connector can be configured for both parts.
The autodisable feature monitors the following to determine if a connector and its respective link are experiencing high error rates:
SNMP traps
Oracle ILOM event log
Syslog
Email alerts
The autodisable feature also monitors the link speed and width, and if any of the following combinations are discovered, the link is considered suboptimal:
1x SDR
1x DDR
1x QDR
4x SDR
4x DDR
Note - If you intentionally configure a link for less than 4x QDR, do not add that connector to the link speed and width part of the autodisable list. It is automatically disabled.
Autodisable functionality is not enabled by default, you must actively configure it by adding connectors to the autodisable list. Additionally, you must actively monitor its operation and take corrective action if necessary. Failure to respond to autodisabled connectors and their links results in a degraded InfiniBand fabric.
Note - Because of its silent nature, have redundancy for autodisable configured links.
You can monitor autodisable configured connectors and their links using the listlinkup command or the Fabric Monitor. For both interfaces, a connector which has been autodisabled is identified with the text AutomaticHighErrorRate, AutomaticBadSpeedOrWidth, or both.
Removing a connector from the autodisable list stops autodisable functionality for that connector and its link. However, it does not re-enable an autodisabled connector or its link. You must investigate the condition of the disabled cable and connector and replace it if necessary. You can then re-enable an autodisabled connector with the --automatic option of the enableswitchport command.
