Define a host

Using ThinkSystem System Manager, you define the hosts that send data to the storage array. Defining a host is one of the steps required to let the storage array know which hosts are attached to it and to allow I/O access to the volumes. You can define a host automatically or manually.

Note: If you installed the Host Context Agent on every host connected to the storage array, the host is already defined.Select Storage > Hosts. to see the automatically defined hosts. Verify that the information provided by the HCA is correct (name, host type, host port identifiers). The host type should be Linux DM-MP (Kernel 3.10 or later).

Keep these guidelines in mind when you manually define a host:

  1. Select Storage > Hosts.
  2. Click Create > Host.
    The Create Host dialog box appears.
  3. Select the settings for the host as appropriate.
  4. Click Create.

After the host is successfully created, ThinkSystem System Manager creates a default name for each host port configured for the host.

The default alias is <Hostname_Port Number>. For example, the default alias for the first port created for host IPT is IPT_1.
