Introduction HP-UX 11i v3 introduces a new representation of mass storage devices called the agile view. The central idea of the agile view is that disk and tape devices are identified by the actual object via its World Wide Identifier (WWID) and not by a path to the device. Paths to a device can change dynamically, and multiple paths to a single device can be transparently treated as a single virtualized path, with I/O distributed across those multiple paths.

List of Impacted Mass Storage Related Hardware The list of impacted mass storage hardware is divided into two different categories, Host Bus Adapters (HBAs) and Peripheral devices. The sub-sections below detail out the impacted list of hardware in each category. If you have any questions about the lists, contact your HP Support Representative. • Unsupported HBAs The table below lists the HBAs that are supported with HP-UX 11i v2 but not supported with HP-UX 11i v3.

Also refer to the migration from Secure Path white paper, “Migrating from HP Storage Works Secure Path for Active-Active Disk Arrays to Native Multipathing in HP-UX 11i v3” available on http://docs.hp.com. HP CIC (DataTap) The HP-UX CIC software initiator is not supported in the initial release of HP-UX 11i v3 and will be automatically removed from the system during update.

Next Steps Note that once you have updated to HP-UX 11i v3, you can take advantage of the agile naming model provided as part of the next generation mass storage stack. For details, refer to the “The Next Generation Mass Storage Stack HP-UX 11i v3” and the “HP-UX 11i v3 Persistent DSF migration” White Papers available on http://docs.hp.com/en/netsys.html#Storage%20Area%20Management.
