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. HP StorageWorks 1500 Modular Smart Array installation guide 17
