Hosts

A host is a computer that runs user applications that consume storage on a networked storage system. There are three types of hosts—Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), and iSCSI.

FC hosts connect to a fabric through Fibre Channel adapters (FCAs) and access storage directly through the array controllers.

FCoE hosts connect to the array through an iSCSI/FCoE module in the P6000 controller (01 or 02).

iSCSI hosts connect to the array through HP iSCSI Connectivity Options or through an FC-iSCSI module in the P6000 controller (01 or 02).

Working with hosts in HP P6000 Command View

The hosts folder for an HP P6000/EVA storage system displays all hosts that have been explicitly added to the HP P6000 Command View interface. You can further organize hosts into subfolders that you create and name. You can also move hosts from one subfolder to another.

(only a portion of the display is shown)

In the various host pages you can view host information and perform actions. For example, you can view general information, presentations, and ports.

Considerations

To access storage on a storage system, you must explicitly add a host using HP P6000 Command View or HP Storage System Scripting Utility.

A host does not have to be online to be added. After it is added, the host must be online and connected to the fabric or bridge to perform I/O to the storage system.
