  • EN1B
  • EN1L
  • EN1M
  • EN1N
  • EN1P

Storage targets

Linux on Power Systems supports attaching Flash systems storage targets by using NVMF-FC, including FS5200, FS7200, and FS9200. For the full list of compatible devices, see IBM System Storage® Interoperation Center (SSIC).

Limitations

The following functions are not supported by NVMF-FC attached LUNS:
  • Installation or Boot
  • kdump or fadump
  • Software RAID
  • To avoid false errors with multipath configuration, the /dev/disk/by-path approach for NVMf-FC is not supported from systemd-254 onwards. You can use /dev/disk/uuid with a filesystem mounted and /dev/disk/by-id with no filesystem mounted for persistence across reboots.
