+ALUA is supported in some devices, but usually it's disabled by default.
+To enable ALUA, the following options should be changed:
+
+- EMC CLARiiON/VNX:
+   "Failover Mode" should be changed to "4".
+
+- HPE 3PAR:
+   "Host:" should be changed to "Generic-ALUA Persona 2 (UARepLun, SESLun, ALUA)".

+- Promise VTrak/Vess:
+   "LUN Affinity" and "ALUA" should be changed to "Enable", "Redundancy Type"
+   must be "Active-Active".
+
+- LSI/Engenio/NetApp RDAC class, as NetApp SANtricity E/EF Series and OEM arrays:
+   "Select operating system:" should be changed to "Linux DM-MP (Kernel 3.10 or later)".
