https://community.ibm.com/community/user/power/blogs/jim-allen1/2020/11/09/installing-aix-on-an-fc-nvme-disk

Requirements:
  * SVC/v7000 v8.4.0 min
  * AIX 7.2 TL 5 and AIX 7.3 
  * Power 9 host (with FW 950 or later) or Power 10 host (FW 1010 or later)
  * FC-NVMe disks required SAN switch attached
  * support only provided for 32Gb FC adapters (EN1A, EN1B), which have at least the 12.4.257.30 (FCode level 12.8.9) adapter firmware level. 
  * This is **not supported via NPIV** from an AIX LPAR: instead the FC adapter must be assigned to the AIX LPAR.
