In Target and LUN Representations, three LUNs are available in each configuration. On the left, the host sees one target, but that target has three LUNs that can be used. Each LUN represents an individual storage volume. On the right, the host sees three different targets, each having one LUN.
Use esxcli storage core to display information about available LUNs on ESXi 5.0. For ESX/ESXi 4.x hosts, use
vicfg-scsidevs. For ESX/ESXi 3.5 systems, the corresponding command is
vicfg-vmhbadevs.
The command lists the primary UID for each device (naa.xxx or other primary name) and any other UIDs for each UID (VML name). You can specify
- -device to only list information for a specific device.

The command lists device information for all logical devices on this system. The information includes the name (UUID), device type, display name, and multipathing plugin. Specify the - -device option to only list information about a specific device. The following example shows output for two devices; the actual listing might include multiple devices and the precise format differs between releases.
