eepromtool
To program FRU format EEPROMS, use the eepromtool. You can also use the eepromtool to show all the FRU-formatted EEPROM
contents or show specific EEPROM content by specifying the EEPROM type.
Tests
NOTE: The eepromtool tool is used during manufacturing to program FRU data.
CAUTION: The eepromtool tool should only be used to read an EEPROM device.
The following command line options are valid cases for running eepromtool in Azul.
1. To list the supported eeprom devices type eepromtool -L
root@dellemc-diag-os:~# eepromtool -L
MC1EEPROM
MC2EEPROM
PSU1EEPROM
PSU2EEPROM
FAN1EEPROM
FAN2EEPROM
FAN3EEPROM
FAN4EEPROM
FAN5EEPROM
IDEEPROM
root@dellemc-diag-os:~#
2. To show a device content type eepromtool -P <EEPROM_DEVICE> -x
root@dellemc-diag-os:~# eepromtool -P PSU1EEPROM -x
