vSphere Storage
vmhbaAdapter:CChannel:TTarget:LLUN
n vmhbaAdapter is the name of the storage adapter. The name refers to the physical adapter on the host, not
to the SCSI controller used by the virtual machines.
n CChannel is the storage channel number.
Software iSCSI adapters and dependent hardware adapters use the channel number to show multiple
paths to the same target.
n TTarget is the target number. Target numbering is determined by the host and might change if the
mappings of targets visible to the host change. Targets that are shared by different hosts might not have
the same target number.
n LLUN is the LUN number that shows the position of the LUN within the target. The LUN number is
provided by the storage system. If a target has only one LUN, the LUN number is always zero (0).
For example, vmhba1:C0:T3:L1 represents LUN1 on target 3 accessed through the storage adapter vmhba1 and
channel 0.
Display Storage Devices for a Host
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 an Adapter
Use the vSphere Client to display a list of storage devices accessible to a specific storage adapter on the host.
Procedure
1 In Inventory, select Hosts and Clusters.
2 Select a host and click the Configuration tab.
3 In Hardware, select Storage Adapters.
4 Select the adapter from the Storage Adapters list.
5 Click Devices.
Copy Storage Device Identifiers to the Clipboard
A storage device identifier is a universally unique ID assigned to a storage device or LUN. Depending on the
type of storage, different algorithms are used to create the identifier and it can be long and complex. You can
copy the storage device identifier directly from the vSphere Client.
Procedure
1 Display a list of storage devices.
2 Right-click a device and select Copy identifier to clipboard.
