For all multipath configurations, all paths for a given LUN must only be accessed by HBAs from the
same vendor (for example, Emulex or QLogic, but not both).
• IBM AIX (Table 104, page 221)
• Sun Solaris (Table 111, page 229)
For all other operating systems, connection to a common server with different HBA vendor products
requires separate HBA zones for each storage system:
• All Fibre Channel HBA zones must contain HBAs from the same vendor.
• A zone can contain different HBA models if they are all from the same HBA vendor.
• A Fibre Channel HBA can be a member in more than one zone.
• All HBA members in the same zone can reside in different servers, but must be the same operating
system type.
Failure to properly zone different HBA models may result in lost connectivity and instability of the
operating system.
Before implementation, contact an HP storage representative for a configuration review.
Common server, common HBA
Simultaneous access to different storage system types from the same HBA is supported for some storage
systems. Each storage system must support identical:
• HBA model numbers
• Driver versions
• Multipathing software versions or compatible multipathing products
See the multipathing coexistence tables (in each operating system's section) for supported storage
system types using common server access with a common HBA:
• HP-UX (Table 97 on page 213)
• HP OpenVMS (Table 99 on page 215)
• HP Tru64 UNIX (Table 101 on page 218)
• IBM AIX (Table 104 on page 221)
• Microsoft Windows (Table 107 on page 224)
• Novell NetWare (Table 109 on page 226)
• Sun Solaris (Table 111 on page 229)
Server zoning rules
A SAN configuration must conform to the zoning requirements of the operating system and other SAN
components. For specific information, see:
• H-series (Table 16 on page 90 and Table 17 on page 91)
• B-series (Table 35 on page 128)
• C-series (Table 52 on page 150 and Table 53 on page 150)
• M-series (Table 69 and Table 70 on page 165)
