Plan carefully when you define a . Because the host runs the storage management software and acts as the primary interface for the administration group, the
host is the single most important component to a well-organized and well-managed .
You must make several decisions before you begin defining a host. Keep these questions in mind before you start to set up
the host:
Do you plan to use on this storage subsystem? Storage partitions can help organize data by dividing disks into partitions that behave as if
they were independent disks.
What is the name of the host? You need the name to determine what host you will use to communicate with the storage subsystem.
To which ports will you be connecting? Verify the connections on the rear of the to determine which HBA is connected to the storage subsystem that you are configuring.
What operating system (OS) does the host use? The OS determines how requests are handled by the storage subsystem when the
host reads data from and writes data to the .
Will this host be part of a ? If so, what is the name of the host group? If the host group does not exist yet, what will the name be, and which hosts
will be part of the group? Depending on your storage subsystem setup, you might determine that the host should share access
to logical drives with one or more other hosts. This situation requires that you set up a host group.
Answer these questions as part of the Define Host Wizard. Planning helps to eliminate mistakes and the need to make corrections
after the host is defined.
