Automatic Load Balancing for Failover Policy
The Promise MPIO solution can load balance the paths for your LUNs with load
balance policy set to Failover.
With Automatic Load Balancing enabled, the LUNs set to Failover policy are
automatically redistributed among all available paths when:
• A path fails
• A failed path comes back online
• A new path is added
Automatic Load Balancing, when enabled, provides optimal data throughput for
LUNs set to Failover policy.
Note that Automatic Load Balancing has NO effect upon LUNs set to Round
Robin, Round Robin with Subset, or Least Queue Depth.
Enabling Automatic Load Balancing
To enable automatic load balancing:
From the Operations menu, choose Auto Load Balance.
When you see a check mark beside Auto Load Balance in the Operations menu,
this feature is enabled.
