Migrating to active/active controllers in Windows environments 9
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.
