and ending when the external LU is blocked.
• Mode: How alternate paths between the local array and external array work. Alternate path
modes include:

LU. When an error occurs in the primary path, the path with the second highest priority is used.
• Multi: Uses all set paths at the same time to execute I/Os to the external LU, distributing the
work load.
