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.
About this task
Keep these guidelines in mind when you 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.
The Create Host dialog box appears.
Select the settings for the host as appropriate.
Type a name for the new host.
Host operating system type
Select the following:
Linux DM-MP (Kernel 3.10 or later)
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 may not be available to select.
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.
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.
