You can display all storage devices or LUNs available to the host, including all local and networked devices. If you use third-party multipathing plug-ins, the storage devices available through the plug-ins also appear on the list.

For each storage adapter, you can display a separate list of storage devices available for this adapter.

Generally, when you review storage devices, you see the following information.

Table 1. Storage Device Information

Storage Device Information

Description

Name

Also called Display Name. It is a name that the ESXi host assigns to the device based on the storage type and manufacturer. You can change this name to a name of your choice.

Identifier

A universally unique identifier that is intrinsic to the device.

Operational State

Indicates whether the device is mounted or unmounted. For details, see Detach Storage Devices.

LUN

Logical Unit Number (LUN) within the SCSI target. The LUN number is provided by the storage system. If a target has only one LUN, the LUN number is always zero (0).

Type

Type of device, for example, disk or CD-ROM.

Drive Type

Information about whether the device is a flash drive or a regular HDD drive. For information about flash drives, see Working with Flash Devices.

Transport

Transportation protocol your host uses to access the device. The protocol depends on the type of storage being used. See Types of Physical Storage.

Capacity

Total capacity of the storage device.

Owner

The plug-in, such as the NMP or a third-party plug-in, that the host uses to manage paths to the storage device. For details, see Managing Multiple Paths.

Hardware Acceleration

Information about whether the storage device assists the host with virtual machine management operations. The status can be Supported, Not Supported, or Unknown. For details, see Storage Hardware Acceleration.

Location

A path to the storage device in the /vmfs/devices/ directory.

Partition Format

A partition scheme used by the storage device. It could be of a master boot record (MBR) or GUID partition table (GPT) format. The GPT devices can support datastores greater than 2TB. For more information, see VMFS Datastores and Storage Disk Formats.

Partitions

Primary and logical partitions, including a VMFS datastore, if configured.

Multipathing Policies (VMFS datastores)

Path Selection Policy and Storage Array Type Policy the host uses to manage paths to storage. For more information, see Understanding Multipathing and Failover.

Paths (VMFS datastores)

Paths used to access storage and their status.
