Defining Host - IBM System Storage DS3500 Introduction And Implementation Manual

Figure 11-2 shows an example of the Mappings tab. The right side of the window lists all
mappings that are owned by the object you selected on the left side. If you highlight the
Storage Subsystem, you see a list of all defined mappings. If you highlight a specific host
group or host, only the associated mappings are listed.

In the following sections, we show how to configure the storage partitioning.
Note:
Before configuring the storage partitions, if you have your storage connected to a FC
switch, make sure to first define the SAN zones appropriately.
Next, perform a hardware rescan on each host that has to be mapped to the DS3500
storage subsystem to reconfigure the FC or SAS devices (HBA) and allow the WWPN
to be presented in the Storage Manager.
It is a best practice to configure only one host HBA per SAN zone along with one
DS3500 storage subsystem controller.

11.2 Defining Host

The Host can be defined as standalone server, or as a cluster member. In the following
section we describe steps how to do it.
Perform the following steps to define host:
1. You have several options to start the host definition in the Topology pane. Right-click your
Storage Subsystem icon, or right-click the Default Group icon, also you can right-click an
existing Host Group. In the menu that appears, select Define  Host, as shown in
Figure 11-3 on page 284. Even with no host group created, it is easier to create the hosts
first and then the host groups. In the Figure 11-3 you can also see that all general
