C.3.8 Controlling Partition Access
The Galaxy 65 Subsystem’s InfoShield capability lets you specify which hosts can access each partition.
This gives you complete control of array access based on your specific needs.
Before you set up InfoShield, you should know the World Wide Name (WWN) for each host that you want
to set up. Your SAN administrator should know the WWNs for your network. You can display a list of the
last 16 WWNs that the Galaxy 65 Subsystem is aware of on the SAN, and you can give each WWN a
nickname of your own. This makes working with the InfoShield feature faster and easier.
You set up InfoShield by either excluding or including hosts on a list for each partition LUN. The list can
include or exclude up to 16 specific hosts or all hosts for each partition LUN.
