You are troubleshooting connectivity issues in your InfiniBand network and need to test basic connectivity...

The tool specifically designed for testingInfiniBand connectivityis **ibping**. It functions similarly to the traditional ping utility but is optimized forInfiniBand fabrics.

From theNVIDIA InfiniBand Diagnostic Utilities Documentation:

"ibping tests the connectivity of InfiniBand nodes by sending management datagrams (MADs) and verifying the response from the destination LID or GUID."

Tests basicnode-to-nodereachability

Supports testing viaLID, GUID, orport number

Helps verify subnet manager routing and fabric health

Incorrect Options:

pingandtracerouteare IP-based, not fabric-aware.

ibnetdiscovermaps topology but doesn't test live connectivity.
