Registering a Host Group and an LDEV Group in a Security Group
After classifying a security group as an access group, the next (and the last) task is to register the
host group and LDEV group into the security group. When you finish registration, the volumes in
the LDEV group are secured and can be accessed only by hosts in the host group. Other hosts
cannot access the volumes
