Automatically disables problematic links.
autodisable subcommand [connector cause][-h]
This hardware command has subcommands that determine its functionality. This table describes the subcommands and provides their syntax.
|
where:
connector is the name of the connector (0A to 17A and 0B to 17B).
cause is the reason to disable the connector:
H – The error rate is higher than what the InfiniBand specification permits.
L – The link speed or width is less than optimal (less than 4x QDR).
This hardware command creates an internal list of connectors that are to be automatically disabled, should the links through the connectors exhibit sub-standard performance. The autodisable list has two parts; one for connectors that experience high error rates on their links, the other for connectors that experience suboptimal link speed and width. A connector can be assigned to both parts of the list.
The H cause is configured for an exceptionally high error rate as seen in:
SNMP traps
Oracle ILOM event log
Syslog
Email alerts
The L cause is configured for a sub-optimal link width or speed. By default, the optimal link speed and width is 4x QDR. Any of these combinations of link speed and width are reason to disable the connector:
1x SDR
1x DDR
1x QDR
4x SDR
4x DDR
If a connector (or port) is intentionally configured for lesser performance, the connector should be removed from the link speed and width part of the autodisable list, otherwise it would be automatically disabled.
When a connector has been autodisabled, the listlinkup command, the Fabric Monitor, and other screen output identify the autodisabled connector with the string AutomaticHighErrorRate, AutomaticBadSpeedOrWidth, or both.
After autodisabling, the connector is re-enabled with the enableswitchport --automatic port command.
The autodisable command is available from the /SYS/Fabric_Mgmt Linux shell target of the Oracle ILOM CLI interface.
This example shows how to use the autodisable command to preemptively autodisable connector 2A when there are too many errors present in the link.
