The Internet Small Computer System Interface (iSCSI) initiator may show the incorrect Multipath I/O (MPIO) path state when you use storage arrays that support ALUA.
iSCSI initiator is not using
MPIO_DSM_Path_V2 WMI Class to show the state, therefore, MPIO setting UI on iSCSI initiator cannot show and set the path state for ALUA.
In Addition, if you set the MPIO load-balancing policy from iSCSI initiator, the state becomes unexpected state. See MPIO_DSM_Path_V2 WMI Class.
Use Device Manager to view and set the MPIO load-balancing policy for storage arrays that support ALUA.
