registered to multiple hosts, only the WWN name with the same name as the host that is already
registered in Device Manager is added to the host. The following shows an example of host detection:
In this diagram, the WWN of 22.22.22.22.22.22.22.22 for host group AAA is added to host AAA,
which has the same name as the host group. The WWN of host group BBB is already registered to
host AAA, and host BBB cannot be registered in Device Manager. Host CCC, which has the same
name as host group CCC, is added to Device Manager, and the WWN of 33.33.33.33.33.33.33.33
for host group CCC is registered to host CCC.
If one host that has multiple WWN is detected, even if it is one host in the actual environment, it might
occasionally be registered as multiple hosts by Device Manager. This is because hosts are generated
in host groups when one host has multiple WWN names. In this case, the hosts must be merged.
Merge the WWN names. Merge the hosts that have been added as multiple hosts in Device Manager
into one host. WWN name information is merged, and the source hosts are deleted automatically.
Registering hosts using host scan
You can register hosts by scanning hosts to manage and monitor the hosts.
Information to check beforehand:
• Host names
• The name of a host group is the same as the actual host, and the WWN name for that host is set
for LUN security.
• Only a single host can be related to each host group.
Tasks to be completed beforehand:
• LUN Manager or LUN Management must be installed on the target storage system.
1. From the Administration tab, select Managed Resources.
2. From the Hosts tab, click Host Scan.
3. Specify the necessary items, and then execute Host Scan.
Registered hosts can be viewed in the resource tree view.
Registering hosts using merge hosts
You can register hosts using Merge Hosts to manage and monitor the host.
