Host terminology
Learn how the host terms apply to your storage array.
Workflow for host creation and volume assignment
The following figure illustrates how to configure host access.
Automatic versus manual host creation
Creating 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 create a host automatically or manually.
How volumes are assigned to hosts and host clusters
For a host or host cluster to send I/O to a volume, you must assign the volume to the host or host cluster.
Access volumes
An access volume is a factory-configured volume on the storage array that is used for communication with the storage array and the host through the host I/O connection. The access volume requires a Logical Unit Number (LUN).
Maximum number of LUNs
The storage array has a maximum number of logical unit numbers (LUNs) that can be used for each host.
