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. |
Example:
ibdiagnet --get_phy_info
ibdiagnet --reset_phy_info
ibdiagnet --get_phy_info -get_ppamp
ibdiagnet --get_phy_info --show_cap_reg
