Configure host access

You can create a host automatically or manually. To make it easier to give multiple hosts access to the same volumes, you can also create a host cluster.

  • Create host automatically
    You can allow the Host Context Agent (HCA) to automatically detect the hosts, and then verify that the information is correct. 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.
  • Create host manually
    For hosts that cannot be automatically discovered, you can manually create a host. 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.
  • Create host cluster
    You create a host cluster when two or more hosts require I/O access to the same volumes.
  • Create volumes
    You create volumes to add storage capacity to an application-specific workload, and to make the created volumes visible to a specific host or host cluster. In addition, the volume creation sequence provides options to allocate specific amounts of capacity to each volume you want to create.
  • Assign volumes to hosts
    You must assign a volume to a host or a host cluster so it can be used for I/O operations. This assignment grants a host or host cluster access to one or more volumes in a storage array.
