1 Migrating single-path standalone systems This chapter provides procedural steps to migrate existing single-path standalone MSA1000 and MSA1500 disk arrays in Windows environments from active/passive to active/active processing. IMPORTANT: Before proceeding, you must understand the following limitations associated with the upgrade: • If HP MPIO Manager for MSA Arrays is installed, it can not be accessed through HP Insight Manager. • If HP StorageWorks Secure Path for Windows is installed, it cannot access or manage HP StorageWorks active/active MSA1000/1500 disk arrays. • HP Windows Full-Featured MPIO Device Specific Module (DSM) requires two separate HBA Fibre Channel paths for its multi-pathing component to function. • MSA1000 environments must have 256MB or greater cache modules installed; 128MB cache modules are not supported in MSA1000 active/active environments. • It is not possible to migrate back to active/passive firmware. Re-loading the older firmware will result in the loss of all configuration information on the MSA. CAUTION: A full backup of Windows system OS and data volumes is required before starting the upgrade process. HP is not responsible for data loss incurred during the upgrade process.
