vSphere Storage Figure 1-5. Target and LUN Representations target LUN LUN LUN storage array target target target LUN LUN LUN storage array In this illustration, three LUNs are available in each configuration. In one case, the host sees one target, but that target has three LUNs that can be used. Each LUN represents an individual storage volume. In the other example, the host sees three different targets, each having one LUN. Targets that are accessed through the network have unique names that are provided by the storage systems. The iSCSI targets use iSCSI names, while Fibre Channel targets use World Wide Names (WWNs). NOTE ESXi does not support accessing the same LUN through different transport protocols, such as iSCSI and Fibre Channel. A device, or LUN, is identified by its UUID name. If a LUN is shared by multiple hosts, it must be presented to all hosts with the same UUID. Storage Device Characteristics 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 1-1. 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. Runtime Name (vSphere Client only) The name of the first path to the device. Operational State Indicates whether the device is mounted or unmounted. For details, see “Detach Storage Devices,” on page 139. 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 solid-state drive (SSD) or a regular non-SSD hard drive. For details, see Chapter 16, “Solid State Disks Enablement,” on page 145. Transport Transportation protocol your host uses to access the device. 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,” on page 198. 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 Chapter 21, “Storage Hardware Acceleration,” on page 215. Location A path to the storage device in the /vmfs/devices/ directory. 18 VMware, Inc.
Table 1-1. Storage Device Information (Continued) Storage Device Information Description 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,” on page 155. 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 Chapter 20, “Understanding Multipathing and Failover,” on page 193. Paths (VMFS datastores) Paths used to access storage and their status. Display Storage Devices for a Host in the vSphere Client Use the vSphere Client to display all storage devices or LUNs available to a host. If you use any third-party multipathing plug-ins, the storage devices available through the plug-ins also appear on the list. Procedure 1 In Inventory, select Hosts and Clusters. 2 Select a host and click the Configuration tab. 3 In Hardware, select Storage. 4 Click Devices. 5 To view additional details about a specific device, select the device from the list. Display Storage Devices for a Host in the vSphere Web Client Display all storage devices available to a host. If you use any third-party multipathing plug-ins, the storage devices available through the plug-ins also appear on the list. The Storage Devices view allows you to list the hosts' storage devices, analyze their information, and modify properties. Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Storage. 3 Click Storage Devices. All storage devices available to the host are listed under Storage Devices. 4 To view details for a specific device, select the device from the list. 5 Use tabs under Device Details to access additional information and modify properties for the selected device. Tab Description Chapter 1 Introduction to Storage Properties View device properties and characteristics. View and modify multipathing policies for the device. Paths Display paths available for the device. Disable or enable a selected path. VMware, Inc. 19
