D.3.8 Controlling Partition Access
The EF2800’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 EF2800 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.
