Registering hosts using host scan – HP XP P9000 Command View Advanced Edition Software Licenses User Manual

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 using host scan to discover hosts so that they can be managed and monitored.
Scanning for hosts automatically creates hosts with host names that match the WWNs that are
registered in the host group on the storage system. For best results, your environment should satisfy
the following conditions:
•
The name of a host group should be 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.
