Specifications

This section also tells you how to change the Sun system kernel. Before you start,
you must meet the attachment requirements listed in “Attachment requirements”.
For procedures on how to attach a SUN host system with SCSI adapters, see
“Attaching with SCSI adapters” on page 99.
Attachment requirements
This section lists the requirements for attaching the ESS to your host system:
v Ensure there are enough fibre-channel adapters installed in the server to handle
the total LUNs you want to attach.
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 compact
disc that you receive with the ESS.
v Solaris 2.6, Solaris 7, and Solaris 8 require patches to ensure that the host and
the ESS function correctly. See Table 20 for the minimum revision level that is
required for each Solaris patch ID.

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 fibre-channel host system with the
worldwide port name identifiers. For the list of worldwide port names, see
“Appendix A. Locating the worldwide port name (WWPN)” on page 153.
3. Either you or an IBM SSR defines the fibre-port configuration if you did not do it
during the installation of the ESS or fibre-channel adapters.
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.
4. Either you or an IBM SSR configures the host system for the ESS by using the
instructions in your host system publications.
Note: The IBM Subsystem Device Driver does not support the Sun host system in
a clustering environment. To have failover protection on an open system, the
