Exalogic Elastic Cloud IB(InfiniBand) Switch Ports State Shown as Down Status Showing AutomaticHighErrorRate Message

Oracle Exalogic Elastic Cloud
I encountered such an error in cloud control: Port IBPort[14] is polling for peer port. This could happen when the cable is unplugged from one of the ends or the other end port is disabled.

In the Exalogic Elastic Cloud racks, you may see issue of IB ports showing status as “Down” when running “ibstat” command.

This issue can of happen on Compute Nodes,İnifiniband Switch or Storage heads. IB port being down on Compute Node can be confirmed by running below command

[root@sp000exl-gwn01 ~]# enableswitchport 8A
Connector 8a switch port 31 not enabled with reason: Disabled but reason: AutomaticHighErrorRate

Verify the Port Status of the Port iba01 you just activated in the iba 01 Switch by running the following command in the Iba 01 Switch.

[root@sp000exl-gwn01 ~]# getportstatus 8A
Port status for connector 8A Switch port 31
Adminstate:………………….Disabled (AutomaticHighErrorRate)
LinkWidthEnabled:…………….1X or 4X
LinkWidthSupported:…………..1X or 4X
LinkWidthActive:……………..4X
LinkSpeedSupported:…………..2.5 Gbps or 5.0 Gbps or 10.0 Gbps
LinkState:…………………..Down
PhysLinkState:……………….Disabled
LinkSpeedActive:……………..2.5 Gbps
LinkSpeedEnabled:…………….2.5 Gbps or 5.0 Gbps or 10.0 Gbps
NeighborMTU:…………………4096
OperVLs:…………………….VL0-7

Step to resolve the IB Port Issue Fix

It can be disabled automatically, it is a feature that can display connectors in the presence of high error rates or insufficient connection speed or width.
This feature does not cause any problems, it just warns the customer with the abnormal condition of the connectors.
The auto-disabled feature is only available in firmware 2.1 and does not apply to firmware 1.3.
The right way to take this into account is to check and ensure that there are automatically disabled ports, and re-enable fwportport – autotomatic ‘before’ up / down by downloading fw to a different version. This will provide compatible settings when moving between different fw.

To re-enable an auto-disabled connector or IB switch port

[root@sp000exl-gwn01 ~]# enableswitchport –automatic Switch 31
