When to Use This Section
Use this section 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 S-series documentation.
For information about the disk drives or tape drives supported on a ServerNet/DA for your
H-series RVU, refer to the H-Series Highlights and Migration Planning Guide.
NOTE: Starting with H06.08, new Integrity NonStop NS14000, NS1200, and NS1000 servers
are shipped with VIO enclosures instead of an IOAM enclosure. VIO enclosures provide the
same functionality as IOAM 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. For more information on VIO enclosures, see:
I/O Adapters and Modules
Beginning with Integrity 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
Integrity NonStop I/O peripherals.
Even though the hardware architecture differs from one series of NonStop servers to another,
the Integrity NonStop system can be networked with other NonStop systems using the same
message system and the same network software.
Fibre Channel ServerNet Adapter (FCSA)
The FCSA provides Fibre Channel connectivity to certain external devices such as disk drives
contained in a disk drive enclosure that supports fibre channel disks and an Enterprise Storage
System (ESS).
Any connection between an Integrity NonStop system and a disk drive enclosure containing
M8xxx fibre channel disks requires the services of two processes: the Fibre Channel Storage (FCS)
Manager, which is part of the Storage Manager ($ZZSTO), and the FCS Monitor $FCSMON), a
persistent generic process that runs in all processors. An FCS Monitor process must be running
in all processors. Each of the two SACs on an FCSA can support as many as four disk drive
