This was my error.  When you select the physical disks you must then "Apply Changes" before hitting the back key. These Seagate branded self-encrypting SSD drives work fine with the PERC H730.
I was hoping to create a RAID 10 with 6 of these drives, but I can't get the PERC controller (fully updated to current firmware package 25.5.9.0001) to use the drives in any manner.  They are recognized and selectable for all types of RAID, but in the last step when I want to create the RAID, the default max size does not fill the "Virtual Disk Size" field, and if I type a size, it reverts to "0".  The Create Virtual Disk icon remains grayed out, no matter what type of RAID or RAID 0 I try to select.  Hard to imagine that these Enterprise drives are not compatible. Has anyone seen something like this or have any suggestions?  These are configured as 4k logical drives. I have Seagate mechanical hard drives (also 4k logical) in other identical R630s and the RAID process is fine.   Thank you in advance.
