Registering hosts
This module describes how to register hosts.
About registering a host
Registering hosts lets you monitor and manage them along with the other registered hosts and storage
systems.
The following hosts can be registered:
• Normal hosts: hosts in an environment where no virtual software is installed
• Virtual servers: hosts in a physical environment where virtual software is installed
• Virtual machines: hosts in a virtual environment created with virtual software
To register a host, specify the IP address and authentication information so can discover it automatically,
or you can add a host manually by specifying the WWN. Virtual server hosts must be registered
manually. Information about a host can be changed after it has been registered.
If you register a host by specifying its IP address and authentication information, the total capacity of
volumes that are allocated to the host can be automatically acquired only if the storage system that
provides the volumes is registered.
You can view information about registered hosts on the Resources tab.
Conditions for acquiring the WWN
If the specified IP address range includes a host with a WWN that is registered, or includes multiple
hosts that have the same WWN, which host acquires the WWN depends on the following conditions:
• A host detected by VMware® ESX (VMware ESX and VMware ESXi) has top priority.
• A host detected by a Device Manager agent has priority over a host detected by the Host Data
Collector.
• If multiple hosts with the same WWN are detected by VMware ESX, the host that was registered
most recently acquires the WWN. The same condition applies for hosts detected by Device
Manager agents. For hosts detected by the Host Data Collector, the host that was registered first
maintains the WWN.
Prerequisites for registering a host
• Target host is connected to the network.
• Target host IP address (IPv4).
• To detect multiple hosts at the same time, specify a subnet or range of up to 256 IP addresses, or
specify individual IP addresses.
