If your Oracle 1.6TB NVMe SSD has firmware RA10 or lower, you must update to RA11 before you update to RA12 or RA13.
The software release includes two firmware files, RA11 and RA13, and associated metadata.xml files that automate the update process. RA11 is bridge firmware to get to RA12 or RA13.
RA13 includes a critical fix where the device might assert at initial power-on. All supported platforms should upgrade to RA13 at earliest convenience.
If your Oracle 1.6TB NVMe SSD has RA11 or RA12, you can upgrade directly to RA13.
If your Oracle 1.6TB NVMe SSD has RA10 or lower, you must upgrade to RA11 before upgrading to RA12 or RA13.
