NOTE: Because enabling Live Volume ALUA is a disruptive process, is should be performed during a maintenance
operation.
5. Click Next.
A dialog box displays a warning message and an option to enable or disable reporting non-optimized paths.
By default, the Report Non-optimized Paths check box is selected. This will cause Live Volumes to report non-
optimized ALUA paths from the secondary system.
If you clear the Reset Secondary Server Mappings check box, Live Volumes will not report non-optimized ALUA paths
from the secondary system.
NOTE: When all paths are reported as non-optimized, Microsoft Multipath Input Output (MPIO) drivers does not
perform round-robin path usage as expected. As a result, data transfer is reduced to a single path and causes a long
delay for failover. Therefore, using non-optimized paths is not recommended in Microsoft Windows environments and
non-optimized path reporting should be disabled.
NOTE: Certain Windows Server 2016 versions can support non-optimized path reporting properly. For more information
and best practice guidelines for configuring MPIO on Microsoft Server 2016, refer to Dell EMC SC Series Storage and
Microsoft Multipath I/O white paper located on the Dell support site.
6. Click Finish.
The results of the ALUA optimization process are displayed.
