Functionality |
Description |
Fabric Discovery |
Sweeps the InfiniBand fabric and collects information from the following InfiniBand devices:
|
Duplicated GUIDs Detection |
Checks and reports duplicated Node and Port GUIDs in the fabric. |
Duplicate Node Description Detection |
Checks and warns regarding duplicated node description of switches or HCAs. |
Alias GUIDs Check |
Performs alias GUID checks (Relevant for ConnectX-3 devices only) |
LIDs Check |
Performs correct LID assignment and duplicated LID check for InfiniBand devices. |
Links in INIT State and Unresponsive Nodes Detection |
Reports links in INIT logical state. Additionally, it reports unresponsive devices and Direct Route to such devices. |
Split Cables Support |
Reports split cables in ibdiagnet dumps and logs. |
Counters Fetch |
Fetches various counters from InfiniBand devices, including standard and extended port counters, diagnostic counters, phy counters, etc. |
Error Counters Check |
Checks errors counters crossing thresholds between counter snapshots. |
Routing Fetch and Checks |
Performs correctness check of the switch routing tables as well as checking of credit-loop free routing. |
Link Width and Speed Checks |
Checks that fabric links are operating at maximum supported speed and width. |
Dumping Virtualization Information |
Dumps virtualization information from channel adaptors. |
Dumping SHARP Trees Structures and SHARP Counters |
|
Dumping SHIELD Configuration and Counters |
|
Topology Matching |
Performs matching of fabric topology with previously stored one. |
Fast Discovery |
Avoids rediscovering the fabric by using previously cached fabric data. |
Support IB Security |
Using MKEY, VSKEY, AMKEY and CC KEY for dumping fabric configuration. |
Partition Checks |
Dumps and validates HCA and switch partition tables. |
BER Test |
Reports links with high Bit Error Rate (BER). |
