disk uncompatible on EVA6300

hi,

I have added EVA SAS disks with below info :

on front of the disks : Spare parts number : 583718-1 and ont he back of the disks :

HP Model : EF0600FATFF

HP P/N : 533871-003

wite sticket : GPN 635330

Firmware : HPD7

to an existing storage EVA 6300 that has disks with attached specs, 

I still cant group the disks with existing ones that are in 2 types :

model number : EF0600FATFF,  firmware version : HPDB

model number EF0600FARNA, firmware verison HPD6

please advise if we can resolve the issue without changing again the disks (this is 2nd time we change them), if its the only option please advise correct model ,

thanks for your quick answer as clientt has production waiting for this extra capacity since 2 months
