12 Implementing an Open IBM SAN
The RS/6000 and pSeries host system does not support more than one host bus
adapter on the loop. The RS/6000 and pSeries host system does support a direct
connection of the RS/6000 and pSeries host system to an ESS using the Fibre
Channel arbitrated loop protocol.
1.4.1 Attachment requirements
This section lists the requirements for attaching the ESS to your host system.
򐂰 Ensure that you have all of the items listed in the Equipment requirements.
򐂰 Ensure that you have the installation script files. These files are on the
diskette and the compact disc you receive with the ESS.
򐂰 Ensure that you have 1 MB minimum of hard disk space available to install
the AIX host attachment package.
򐂰 Ensure that you have the documentation for your host system and the IBM
Enterprise Storage Server User's Guide. The User's Guide is on the compact
disc that you receive with the ESS.
For details about the release level for your operating system, see the following
Web site:
www.storage.ibm.com/hardsoft/products/ess/supserver.htm
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 ESS by using the procedures in the IBM Enterprise
Storage Server Service Guide.
2. Either 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.
3. Either you or an IBM SSR configures the host system for the ESS. Use the
instructions in your host system publications.
Note: For an RS/6000 and pSeries host system, you can use two topologies:
򐂰 Point-to-point (switched fabric) topology
򐂰 Arbitrated loop topology
Note: Use the information on the logical configuration work sheet in the IBM
Enterprise Storage Server Configuration Planner that you previously filled out.
