HP XP P9000 Command View Advanced Edition Software - Manual (Page 34)

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 WWNs 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 WWNs. In this case, the hosts must be merged.
Merge the WWNs . Merge the hosts that have been added as multiple hosts in Device Manager into
one host. WWN 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 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 the host scan.
Registered hosts can be viewed in the resource tree view.
TIP:
If one host has multiple WWNs 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 WWNs . In this case, the hosts must be merged, meaning
merge the WWNs. Merge the hosts that have been added as multiple hosts in Device Manager into
one host, meaning that WWN information is merged, and the source hosts are deleted automatically.
TIP:
To remove registered hosts, select the hosts to be removed, and click Remove Hosts.
