HP StorageWorks 1000 Modular Smart Array installation guide 69
Configuring the storage
Thorough planning is critical to the successful and efficient deployment of any storage array system.
As discussed in Chapter 1: ”Installation procedures—All deployments” on page 13, plans should
include decisions about total system capacity, fault-tolerance, performance, and availability.
Although detailed in the ACU and the CLI user guides, basic configuration tasks include (in the
following sequence):
• 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.
IMPORTANT: In multipath configurations:
• 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 Linux
environments, HBA load balancing is set via a driver command line option.
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.
