ibdiagnet Functionality
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). |
Dump PCI Data from Servers | |
Dump Cable Info | |
Dump PHY Info |
