Registering hosts using host scan – HP XP Array Manager Software User Manual
Page 38
TIP:
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 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.
Prerequisites
Tasks to be completed beforehand:
•
Install LUN Manager or LUN Management on the target storage system.
1.
On the Administration tab, select Managed Resources.
2.
On the Hosts tab, click Host Scan.
3.
Confirm that your environment meets the recommended conditions, and then select storage systems
on which to scan for hosts.
4.
Click OK to begin the host scan.
Registered hosts can be viewed in the resource tree view.
