Chapter 10. Attaching to a Sun host

This chapter tells you how to attach an ESS to a Sun Microsystem host system with

SCSI or fibre-channel adapters. You must install the SCSI adapters in the Sun host

system before you start.

Attaching with SCSI adapters

This section describes how to attach an ESS to a SUN host system with SCSI

adapters. For procedures on how to attach an ESS to a SUN host system with

fibre-channel adapters, see “Attaching with fibre-channel adapters” on page 104.

Attachment requirements

This section lists the requirements to attach the ESS to your host system:

v Check the logical unit number limitations for your host system. See Table 6 on

page 11.

v 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 CD that you

received with the ESS.

v See the following Web site for details about the release level for your operating

system:

www.storage.ibm.com/hardsoft/products/ess/supserver.htm

v Solaris 2.6, Solaris 2.7, and Solaris 8 require patches to ensure that the host and

ESS function correctly. See Table 18 for the minimum revision level that is

required for each Solaris patch ID

v Review the Sun host SCSI adapter device driver installation and configuration

utility documents for additional Solaris patches that you might need.

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. You assign the SCSI hosts to the SCSI ports on the ESS.

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.

3. You configure the host system for the ESS. Use the instructions in your host

system publications.
