16 Implementing an Open IBM SAN
The ESS also offers the following interim support for Fibre Channel attachment:
Feature Code 3019 — With the feature code 3019, you can attach an ESS to an
xSeries or an IBM NUMA-Q host system through the NUMA-Q Fibre Channel- to-
SCSI bridge. This feature code includes one SCSI adapter that you purchase
and a no-cost loan of a NUMA-Q Fibre Channel to SCSI bridge. IBM requires
that you sign a loan agreement for the bridge.
For more information about how to attach an xSeries or a NUMA-Q host system
with Fibre Channel adapters, see the NUMA-Q ESS Integration Release Notes
and the Fibre Channel Subsystem Installation Guide. To obtain a copy, see your
IBM sales representative.
1.5.1 Attachment requirements
This section lists the requirements for attaching the ESS to your host system.
Either you or an IBM service support representative (SSR) must perform the
following tasks to install and configure an ESS:
1. The IBM SSR installs the IBM ESS by using the procedures in the IBM
Enterprise Storage Server Service Guide.
2. Either you or the IBM SSR defines the Fibre Channel host system with the
worldwide port name identifiers. For information about how to locate the
worldwide port name for an xSeries or an NUMA-Q host system, see 1.12,
“Locating the worldwide port name” on page 69.
3. Either you or the IBM SSR defines the Fiber Channel port configuration if you
did not do it during the installation of the ESS or Fibre Channel adapters.
4. Configure your host system for the ESS by using the instructions in your host
system publications.
1.5.2 xSeries and NUMA-Q system requirements
The ESS is supported on the xSeries and the NUMA-Q host systems by a
module of code that is incorporated into Service Pack 3 for PTX V4.5.2. To install
Service Pack 3:
Note: Feature code 3019 is not a standard feature. To get feature code 3019,
contact your IBM sales representative.
