C.3.8.3 Configuring InfoShield
. Once you set up host nicknames, you can easily set up your InfoShield. This is where you determine
which hosts can access each partition LUN.
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.
The InfoShield information is stored as part of the array’s metadata using the WWN for each host. If you
install a new SM, the array partition’s InfoShield will remain. The InfoShield will also remain if you change
the partition’s LUN.
Note Changes to InfoShield take effect immediately, therefore, you should make changes that limit access to
partitions when the partitions are not in use.
