Plan carefully when you define a . Because the host runs the , controls the for the , and is the primary interface for the administration group, the host is the most important component in a well-organized
and well-managed storage array.
Planning helps prevent mistakes and the need to make corrections after the host is defined. You must make several decisions
before you start defining a host.
Do you plan to use on this storage array? 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 find out what host you will use to communicate with the storage array.
To which ports or will you be connecting? Examine the connections on the host to find out which or iSCSI initiator is connected to the storage array that you are configuring.
What does the host use? The OS controls how requests are handled by the storage array when the host reads and writes data to the
virtual disks.
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 array setup, you might determine that the host should share access to
virtual disks with one or more other hosts. This requires that you set up a host group.
