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 15: "Hard drive information" on page 114 and Table 16: "Array (LUN) information" on page 118 to record information about your storage.

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.
