Updating MSA controller firmware (if necessary)
If you need to update the firmware on your MSA controller to a version downloaded from the Web,
do so at this time.
For information on determining whether you need to update MSA controller firmware, see the
following sections in this guide:
• ” Determine which version of MSA controller firmware to use ” on page 15
• ” Obtain desired controller firmware and Support Software CD versions ” on page 56
For instructions on updating MSA controller firmware, see the MSA 1000/1500 firmware updating
guide, available on the MSA1500 website: http://www.hp.com/go/msa1500cs .
IMPORTANT: After updating MSA controller firmware, be sure to check the status of the MSA for
unexpected issues. Verify the status of the connections, defined profile types, redundancy settings,
and storage configuration.
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 levels (availability), and performance.
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 indeed 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.
