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, 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 multipath configurations, HP recommends disabling host-based
■
Fibre Channel HBA load balancing. By default, MSA firmware balances the LUNs
between the two MSA controllers. (Or optionally, you can manually specify the
preferred controller path for each LUN.) If HBA load balancing is also enabled at
the host, the host instructions will override the MSA instructions, resulting in
additional processing time and reduced performance. In Windows environments,
HBA load balancing is set in the HP MPIO DSM Manager.
Perform these tasks using your chosen configuration utility. Refer to the
appropriate user documentation for instructions.

Creating the arrays (LUNs).
Entering global 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:
