Troubleshooting Scenarios
A.2.1
InfiniBand
This section documents common problems seen with the SilverStorm 9000 series
switches.
A.2.1.1
Invalid IP Address entered 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
1. Invalid IP Address entered for the chassis or spine modules via the console
port. Use the
showChassisIpAddr command to be sure the address has been
set correctly.
2. If attempting to access the switch from a remote LAN, ensure that the default
gateway/default route addresses are set correctly.
A.2.1.2
Nodes cannot be seen in SilverStorm Fabric Viewer
Symptoms
When viewing the IB fabric with the SilverStorm Fabric Viewer, no nodes are
seen.
Resolution / Workaround
1. Possibly a bad IB cable(s). Ensure that there is a Blue LED illuminated on the
leaf module IB ports of the switch. Make sure that all devices (nodes) can be
seen in the Fabric Viewer window.
2. Check the cables and connections subnet manager and the rest of the fabric.
3. The subnet manager may not be running on the IP address specified in Fabric
Viewer. Check the IP address and make sure the subnet manager is in the
Active state on that node. Depending on the configuration of that node, following
a reboot the subnet manager may or may not restart.
