When to Use This Chapter
Use this chapter for monitoring and recovery information for the Fibre Channel ServerNet adapters
(FCSAs) and the Gigabit Ethernet 4-port adapter. Information on ServerNet/DAs, the IOMF2
enclosure, and the I/O adapter module (IOAM) is available in NonStop NS-series documentation.
NOTE: Some NonStop systems are shipped with VIO enclosures instead of an IOAM enclosure.
VIO enclosures provide the same functionality as IOAM enclosures. If your NonStop system is
equipped with VIO enclosures, refer to the planning guide for your system for information about
its VIO enclosures.
The monitoring and recovery principles described in this chapter are essentially the same for VIO
enclosures; however, the components and OSM object names vary as follows:
• Fibre Channel ports are in slots 1 and optionally in 7 and are identified as FCSA in OSM.
• Gigabit Ethernet ports are in slots 6 and optionally in 7 and are identified as G4SA in OSM.
For more information on VIO enclosures, see the Versatile I/O (VIO) Manual.
I/O Adapters and Modules
Beginning with NonStop systems, interprocessor communications and I/O use dual ServerNet
fabrics as a common interconnect means. Input/output components usually connect to the ServerNet
fabrics through ServerNet adapters that are in an I/O adapter module (IOAM) enclosure. These
adapters provide the system I/O to Fibre Channel storage devices and gigabyte Ethernet
communications networks. Connections to the ServerNet fabric through a NonStop S-series I/O
enclosure equipped with IOMF2s provide additional ServerNet interfacing for the NonStop I/O
peripherals.
Even though the hardware architecture differs from one series of NonStop systems to another, the
NonStop system can be networked with other NonStop systems using the same message system
and the same network software.
