Recovering from ISO installation failure due to mismatched HDD and SSD

Resolve ISO installation failures that are due to a mismatched HDD and SSD.

Symptom

A node will boot to login, but after the login, all hardware models will display as UNKNOWN.

Possible root cause

The data SSD and HDD combination doesn’t match the required, predefined HDD and SSD combination in the Bill of Materials (BOM). The software uses the combination of SSD capacity and HDD capacity to determine a hardware model. If the combination doesn’t match the BOM database, the software would fail to identify the product model.

Solution

Verify the storage device inventory with lsblk command in the Linux® CLI or use the vendor’s BMC web GUI to check the hardware inventory against the expected combination.
