Troubleshooting Scenarios

InfiniBand

This section documents common problems seen with the SFS 7024 switch.

Invalid IP Address entered for SWC via Console Port

Symptoms

Cannot access the Chassis Viewer browser window. The browser window times out and Chassis Viewer will not come up.

Resolution / Workaround

Invalid IP Address entered for switch card via the console port. Make sure configuration is using a valid IP address for the Switch (make sure initial configuration for switch is correct using the console port during the boot sequence).

Bad IB Cable

Symptoms

When viewing the IB fabric with a subnet manager viewer, no nodes will be seen, or only the nodes that have a good IB connection will be seen.

Resolution / Workaround

Possibly a bad IB cable(s). Ensure that there is a Blue LED illuminated on the leaf module IB ports of the SFS 7024 switch. Make sure that all devices (nodes) can be seen in the subnet manager window.

Improperly Seated IB Cable

Symptoms

When viewing the Subnet Manager no nodes will be seen, or only the nodes that have a good IB connection will be seen.

Resolution / Workaround

Possibly an improperly seated IB cable(s). Ensure that there is a Blue LED illuminated on the switch. Make sure that all devices (nodes) can be seen in your Subnet Manager window.
