About merging hosts
WWN names that are registered to multiple hosts can be merged into one destination host. The source
host will be deleted upon completion of the merge.
Information about WWN names are also merged. If the host that is monitored by the Host Data
Collector or Device Manager agent is merged as a source host, the source IP address will not be
migrated.
Prerequisites for merging hosts
Before you merge hosts, the destination host cannot be:
• mainframe
• virtual
• not registered with a WWN
