HP StorageWorks 1500 Modular Smart Array installation guide 17
NOTE: When examining the available firmware versions, consider the following:
• The MSA ships with a single controller and active/passive firmware pre-installed. If you plan to
install an additional MSA controller and are interested in upgrading to active/active, consider
the complexity of your SAN, including the variety of device types, operating systems, failover
tools, and access requirements.
• Confirm the latest list of supported operating systems, servers, Host Bus Adapters, and any
homogeneous/heterogeneous network limitations for the different MSA firmware versions. See
the two versions (active/active and active/passive) of the compatibility guide, available on the
Technical documentation page of the MSA1500 website: http://www.hp.com/go/msa1500cs .
• After upgrading the MSA to active/active firmware, it is not possible to downgrade at a later
time to an active/passive version. Re-loading the older, active/passive firmware will result in the
loss of all configuration information on the MSA.
• The active/active firmware is supported for use only on MSA with 256MB or greater controller
cache modules. Before upgrading to active/active firmware, verify that both MSA controllers
meet this requirement.
• For information on upgrading the MSA to active/active, see the migration instructions for your
operating system, available on the Technical documentation page of the MSA1500 website:
http://www.hp.com/go/msa1500cs .
Complete the planning worksheet on the poster
The printed installation and configuration overview poster, included in the shipping carton, is a
companion to this installation guide, and should be completed before installing your MSA.
Use the poster to:
• Gather all of the components necessary for installing your MSA.
• Verify that the components you plan to use are supported for use with the MSA and your
operating system environment.
•
Record important information about the components that you plan to use.
• Learn about this installation process.
In addition to the poster, see and record system information on the ” Worksheets ” on page 107.
Information in these worksheets is required for multipathing, future configuration changes, and
troubleshooting purposes.
NOTE: If a supplier is installing the MSA for you, be sure that they complete these worksheets.
