Proliant DL360 Gen 8 and HPE Dual 8GB microSD EM USB kit

Hi all,

i always received my brand new proliant with embedded HPE Dual 8GB microSD EM USB kit and never had problems.

Here i have an existing DL360 Gen 8, that i updated with HP SPP 1704 (sems the best for gen 8, can someone confirm ?) and when i install ESXi custom image (VMware-ESXi-6.5.0-Update2-9298722-HPE-preGen9-650.U2.9.6.8.3-Sep2018.iso) it told me that there is 0 MiB on the card.

I put it in my laptop and can only see 47Kb VFS LUN with some .TXT on it.

I read the user doc, they say it is ready to use, nothing about a way to initialize it.

Can somebody give me some hint about what i could do ?

Thanks
