Understanding Service Procedures
To perform a quick check of all ports of all nodes in your InfiniBand fabric, you can use the ibcheckstate command.
On the management controller, type:
# ibcheckstate -v # Checking Switch: nodeguid 0x0021283a8620b0f0 Node check lid 25: OK Port check lid 25 port 36: OK Port check lid 25 port 35: OK Port check lid 25 port 34: OK Port check lid 25 port 33: OK Port check lid 25 port 32: OK . . . Port check lid 22 port 6: OK Port check lid 22 port 9: OK # Checking Switch: nodeguid 0x0021283a8620b0e0 Node check lid 24: OK Port check lid 24 port 22: OK . . . Port check lid 24 port 30: OK Port check lid 24 port 29: OK ## Summary: 6 nodes checked, 0 bad nodes found ## 142 ports checked, 0 ports with bad state found #
Note - The ibcheckstate command requires time to complete, depending upon the size of your InfiniBand fabric. Without the -v option, the output contains only failed ports. The output in the example is only a small portion of the actual output.
