Chapter 1. Implementing Fibre Channel host adapter cards 59
Either you or an IBM SSR must perform the following tasks to install and
configure an ESS:
1. The IBM SSR installs the ESS by using the procedures in the IBM Enterprise
Storage Server Service Guide
2. You or an IBM SSR defines the Fibre Channel host system with the worldwide
port name identifiers.
3. You or an IBM SSR defines the Fiber Channel port configuration if you did not
do it during the installation of the ESS or Fibre Channel adapters. For the list
of worldwide port names, see 1.12, “Locating the worldwide port name” on
page 69.
4. Either you or an IBM SSR configures the host system for the ESS by using
the instructions in your host system publications.
1.11.2 Installing the QLogic QLA2100F adapter card
This section tells you how to attach an ESS to a Windows NT host system with
the QLogic QLA2100F adapter card. Single-port Fibre Channel interfaces with
the QLogic QLA2100F adapter card support the following loop modes:
򐂰 Tar ge t
򐂰 Initiator
򐂰 Target and initiator
Note: Use the information on the logical configuration work sheet in the IBM
Enterprise Storage Server Configuration Planner that you should have
previously filled out.
Note:
1. The IBM Subsystem Device Driver 1.2.1 does not support the Windows
2000 host system in a clustering environment. To have failover protection
on an open system, the IBM Subsystem Device Driver requires a minimum
of two Fibre Channel adapters. The maximum number of Fibre Channel
adapters supported is 16 for a total of 16 Fibre Channel ports.
2. To improve performance, IBM recommends that you map to the LUNs for
the target volumes of the Windows 2000 host until you need access to the
data on the target volume. Perform the LUN mapping after the PPRC
operation and immediately before you need access to the data. You must
restart the host system before you can access the data on the target
volume. You can greatly reduce the time it takes for the host system to
restart if you perform the LUN mapping. Otherwise, the time to restart could
take 10 minutes per PPRC target volume.
