vpd-tool --mfgClean implementation
vpd-tool supports a new option --mfgClean, which cleans specific
keywords in system backplane VPD and restore it with their default
value.
This option will be used to ensure that the VPD is properly defaulted
in the FRU stock.
The FAB test will make use this option to reset system
backplane VPD keywords to its defaults.
vpd-tool --mfgClean --yes
====================
Test:
./vpd-tool --mfgClean
This option resets some of the critical keywords in System Backplane VPD
to its default value. Do you really wish to proceed further?[yes/no]: yes
The critical keywords from system backplane VPD has been reset successfully.
./vpd-tool --mfgClean --yes
The critical keywords from system backplane VPD has been reset successfully.
Verified that the critical keywords have been reset to defaults.
