Configuring the storage

Thorough planning is critical to the successful and efficient deployment of any
storage array system. As discussed in Chapter 1:
All Deployments" on page 15, plans should include decisions about total system
capacity, fault-tolerance levels (availability), and performance.
Although detailed in the ACU and the CLI user guides, basic configuration tasks
include (in the following sequence):
■
■
■
■
■
Important:
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.

Creating the arrays (LUNs).
Entering controller settings, such as setting the read/write cache ratio, setting
the rebuild/expand priority, and setting the redundancy level.
Identifying the operating system type (also called Host Mode, Access Mode,
Profile, or Connection Profile) of each HBA with access to the MSA. This
ensures that the MSA will communicate properly with that host.
Verifying that each HBA with access to the MSA is visible to the MSA.
Entering Selective Storage Presentation options (also called Access Control
Lists) to isolate the storage from unauthorized access. These settings indicate,
by HBA, which LUNs the HBA can access.
In multi-path configurations:
