HyperFabric Administrator's Guide (HP-UX 11i v1)

Planning the Fabric
TCP/UDP/IP
Chapter 216
TCP/UDP/IP
TCP/UDP/IP is supported on all HF1 and HF2 hardware. Although some
of the HyperFabric adapter cards support both HMP and TCP/UDP/IP
applications, in this section, the focus is on TCP/UDP/IP HyperFabric
applications.
Application Availability
All applications, including Oracle 9i and HP-MPI, that use the
TCP/UDP/IP stack are supported.
Features
This section discusses the following HyperFabric features on
TCP/UDP/IP:
• OnLine Addition and Replacement (OLAR): Supported
The OLAR feature allows the replacement or addition of
HyperFabric adapter cards while the system (node) is running.
HyperFabric supports this functionality on the rp54xx (L-class),
rp74xx (N-class), rp8400 and Superdome systems, running on the
HP-UX 11i v1 platform with patch PHNE_27745.
For more information on OLAR, including instructions for
implementing this feature, see “Online Addition and
Replacement—HP-UX 11i v1 Only” on page 52 and Configuring
HP-UX for Peripherals Part Number B2355-90698 November 2000
Edition.
• Event Monitoring Service (EMS): Supported
Starting with December 2000 releases of HyperFabric (B.11.00.11
and B.11.11.01), the HyperFabric EMS monitor enables the system
administrator to separately monitor each HyperFabric adapter on
every node in the fabric, in addition to monitoring the entire
HyperFabric subsystem. The monitor can inform the user if the
resource being monitored is UP or DOWN. The administrator defines
the condition to trigger a notification (usually a change in interface
status). Notification can be accomplished with one of the following:
— A Simple Network Management Protocol (SNMP) trap
