PHY Diagnostics

PHY diagnostics plugin collects NVIDIA® Mellanox® Vendor-Specific Data from NVIDIA devices including BER data, low level PHY counters, sensors, fans, PSUs, etc.

Collected information is dumped into ibdiagnet2.db_.csv file under following sections:

PHY_DBs
FANS_SPEED
FANS_THRESHOLDS
FANS_ALERT
FAN_SERIAL_NUMBERS
TEMPERATURE_SENSORS
TEMPERATURE_ALERTS
POWER_SENSORS
PSU information
- NodeGuid, PSUIndex,IsPresent, IsFRU, ACInput, DCState, AlertState, FanState, TemperatureState, SerialNumber
SYSTEM_GENERAL_INFORMATION
- NodeGuid, SerialNumber, PartNumber, Revision, ProductName
PHY_PORT_GRADE

Parameter	Description
--get_phy_info	Queries all ports for PHY information including BER counters. Data will be dumped to the ibdiagnet2.db_csv and ibdiagnet2.net_dump_ext files.
--reset_phy_info	Queries and clears all ports PHY information. Note: It is recommended to use this option with `–pc`, as both options have cross counters and using only one of them can be confusing on the next iteration of counters or registers collection.
--get_ppamp	Queries all ports for PPAMP (Port Phy opAMP data), works with `--get_phy_info`. Data will be dumped to the ibdiagnet2.db_csv file.
--show_cap_reg	Indicates to dump also capability registers, works with `--get_phy_info`. Data will be dumped to the ibdiagnet2.db_csv file.
