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 . 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:
- You must define the host
identifier ports that are associated with the host.
- Make sure that you provide
the same name as the host's assigned system name.
- This operation does not
succeed if the name you choose is already in use.
- The length of the name cannot
exceed 30 characters.
- Select .
- Click .
The Create Host dialog box appears.
- Select the settings
for the host as appropriate.
Field details
| Setting |
Description |
| Name |
Type a name for the new host. |
| Host operating system type |
Select Linux DM-MP (Kernel 3.10 or
later) from the drop-down list. |
| Host interface type |
Select the host interface type that you want
to use. If the array you configure only has one available host interface
type, this setting might not be available to select. |
| Host ports |
Do one of the following:
- Select I/O Interface
If the host ports have logged in, you can select host port identifiers
from the list. This is the recommended method.
- Manual add
If the host ports have not logged in, look at /etc/nvme/hostnqn on the host to find the hostnqn identifiers and associate them with
the host definition.
You can manually enter the host port identifiers
or copy/paste them from the /etc/nvme/hostnqn file
(one at a time) into the Host ports field.
You must add one host port identifier at a time to
associate it with the host, but you can continue to select as many
identifiers that are associated with the host. Each identifier is
displayed in the Host ports field. If necessary,
you also can remove an identifier by selecting the X next to it.

- 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.
