|
|
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. |
