Hello,   This isn't a supported operation. The drives used in Unity systems have special firmware flashed on them that can't be flashed onto drives after they leave. I would expect it may also be the case that they won't accept alternate firmware, but can't confirm that.    Someone here in the community may have found success doing something similar, but with this being unsupported, there isn't an additional recommendation we can make.
We have a bunch of DELL EMC MZ-ILT3T8A SAS SSD's that came out of Unity storage clusters.  We would like to use them in our PowerEdge R640's but the drives show up unsupported in PERC due to their Unity Firmware REV ESFA. We can't even build a RAID with them.   I can't access them from Windows to use Samsung's firmware utility or to use Dell's FW installer to apply FW REV DSF8.   How would I flash these drives firmware so they would be usable in a poweredge?
How do I reflash a DELL EMC SAS SSD that has Unity firmware to normal firmware 
for use in a PowerEdge?
