IMPORTANT: In multipath configurations:

• Verify that both HBAs in each server have been granted access to the storage.

• In active/active configurations, manually assign a preferred path (controller ownership) for each

LUN. By default, MSA firmware initially assigns ownership of all LUNs to the controller in slot

one (front-right) of the MSA. Then, based on access patterns and I/O load, the firmware

automatically re-assigns ownership of the LUN between the controllers to balance the load. If

your environment controls load balancing from the host, you must manually assign the preferred

path for each LUN.

Perform these tasks using your chosen configuration utility. Refer to the appropriate user

documentation for instructions.

Go to Table 13: ”Hard drive information” on page 112 and Table 14: ”Array (LUN) information” on

page 116 to record information about your storage.
