+ALUA
+====
+This is a rough guide, consult your storage device manufacturer documentation.
+
+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" or "Active-Active mode(ALUA)-failover mode 4"
+
+- HPE 3PAR, Primera, and Alletra 9000:
+ "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)".
+
+- NetApp ONTAP:
+ To check ALUA state: "igroup show -v <igroup_name>", and to enable ALUA:
+ "igroup set <igroup_name> alua yes".
+
+- Huawei OceanStor:
+ "Host Access Mode" should be changed to "Asymmetric".
