HP-UX 11i v3 Read Before Installing or Updating, February 2007 (Initial Release)

• New view of mass storage, called the agile view. This
view includes:
• New naming convention for persistent disk and
tape device special files
• New minor number format that supports much
larger I/O configurations
The agile view also represents hardware pathing to
disk and tape devices in ways that support larger
configurations and transparent multi-pathing. By
default, most commands show a legacy view of mass
storage compatible with prior releases. Users select
the agile view with new command line options or GUI
toggles, as documented for each command or tool.
• The next generation mass storage stack enables
enhanced storage scalability such as:
• Unlimited number of I/O busses, up from 256
• 16384 LUNs supported per system, up from 8192
active LUNs
• LUN size over 2TB
• 32 distinct I/O paths to a LUN, up from 8
