Registering hosts using merge hosts
You can use merge hosts to combine source and target host information into a single surviving target
host that is registered.
Prerequisites
Tasks to complete beforehand:
•
Identify the names of the source and target host. Note that the source host is merged into the target
host, then the source host is deleted.
•
Ensure the source host has been registered either manually or by host scan
•
Ensure the target host is not a mainframe host, or a virtual host
•
Ensure the target host has at least one registered WWN.
1.
From the Administration tab, select Managed Resources.
2.
Select the Hosts tab, select the target host row, click More Actions and select Merge Hosts.
3.
In the merge hosts window, select the source host, then click Confirm.
4.
Review the target (surviving host) and source (host to be deleted) information.
• If the target and source host information is correct, click OK.
• If the target or source host information must be changed, click Back.
• To abandon the task, click Cancel.
On the Resources tab, in the hosts tree, confirm the target host information and the source host removal.
You can also confirm this on the Administration tab in the Hosts tree under Managed Resources.

About changing host settings and information
You can change host settings and update previously registered host information.
Depending on how a host is registered, you change host settings and information by using either of
the Refresh Hosts or Edit Hosts options. The Refresh Hosts option updates a host by obtaining
information from Host Data Collector or Device Manager agent. The Edit Hosts option allows you to
manually change host settings.
If a host accesses storage using a FC or FCoE connection, you must change host group names, host
modes, and host mode options using the Edit Hosts option.
When replacing host HBAs, you can exchange WWN settings in the LUN paths so that the new HBA
inherits the WWN settings from the old HBA. The operation is performed from the Exchange HBAs
dialog box when you replace a host HBA due to failure, and from the Add HBAs dialog box and the
Remove HBAs dialog box when performing a planned HBA replacement due to scheduled maintenance
to prevent performance degradation.
