6.3 Resolving a Configuration Mismatch
If the replacement controller has a previous configuration, this message
displays during the power-on self-test (POST):
Unresolved configuration mismatch between disk(s) and NVRAM
on the adapter
A configuration mismatch occurs when the configuration data in the
NVRAM and the configuration data on the drives are different. To resolve
this, update the configuration data in the NVRAM with the data from the
physical disk. To update the configuration data, follow these steps:
1. Press CTRL+M when prompted during boot-up to access the
BIOS CU.
2. Select Configure -> View/Add Configuration .
