Hi [NAME]  Thank you for your reply. As a precaution the Unity arrays has a set of drives that hold a copy of the code and are used as Vault drives, more specifically drives 0 to 4 of the DPE. When the internal SSD is replaced on a Storage Processor, the system will then install the OS into the new M.2 SSD. I hope that this information is useful, however if you have any other queries, please let me know by replying to this message.
Hi,   can it happen that a shipped SP has a different OE/ or a shipped SP contain an OE lower/higher than the array ?   Many THanks, Vivek
SP replacement - different firmware ?
