An ESX Server creates SCSI logical unit objects to represent devices in the host configuration. (See the definition of ScsiLunType for a list of the supported device types.) The vSphere API uses one of two object types to represent a SCSI logical unit, depending on the device type.
When the Server creates a HostScsiDisk or ScsiLun object, it specifies a valid device name and type:
/dev/cdrom
/vmkdev/vmhba0:0:1:0
PhysicalDrive0
scsi-cdrom
scsi-tape
scsi-disk
scsi-processor
scsi-unknown
Properties
Name | Type | Description |
---|---|---|
alternateName* | ScsiLunDurableName[] |
Alternate durable names.
Records all available durable names derived from page 80h of the Vital
Product Data (VPD) and the Identification Vital Product Data (VPD) page
83h as defined by the SCSI-3 Primary Commands. For devices that are not
SCSI-3 compliant this property is not defined.
Since VI API 2.5 |
canonicalName* | xsd:string |
Canonical name of the SCSI logical unit.
Disk partition or extent identifiers refer to this name when referring to a disk. Use this property to correlate a partition or extent to a specific SCSI disk.
|
capabilities* | ScsiLunCapabilities |
Capabilities of SCSI device.
Since vSphere API 4.0 |
descriptor* | ScsiLunDescriptor[] |
List of descriptors that can be used to identify the LUN object. The
uuid will also appear as a descriptor.
The id field in the descriptor is a string that can be used to correlate the ScsiLun across multiple servers. A ScsiLun may have multiple descriptors. The choice and order of these descriptors may be different on different servers. Not all descriptors are suitable for correlation. Some descriptors are only sufficient to identify the ScsiLun within a single host. Each descriptor contains a quality property that indicates whether or not the descriptor is suitable for correlation. Since vSphere API 4.0 |
displayName* | xsd:string |
User configurable display name of the SCSI logical unit. A default
display name will be used if available. If the display name is not
supported, it will be unset. The display name does not have to be
unique but it is recommended that it be unique.
Since vSphere API 4.0 |
durableName* | ScsiLunDurableName |
The durable name of the SCSI device.
For a SCSI-3 compliant device this property is derived from the
payloads of pages 80h and 83h of the Vital Product Data (VPD) as
defined by the T10 and SMI standards. For devices that do not provide
this information, this property is not defined.
|
key* | xsd:string |
Linkable identifier
|
lunType | xsd:string |
The type of SCSI device. Must be one of the values of
ScsiLunType.
|
model* | xsd:string |
The model number of the SCSI device.
|
operationalState | xsd:string[] |
The operational states of the LUN.
When more than one item is present in the array, the first state
should be considered the primary state. For example, a LUN may
be "ok" and "degraded" indicating I/O is still possible to the LUN, but
it is operating in a degraded mode. See ScsiLunState |
protocolEndpoint* | xsd:boolean |
Indicates that this SCSI LUN is protocol endpoint. This
property will be populated if and only if host supports
VirtualVolume based Datastore. Check the host capability
virtualVolumeDatastoreSupported.
See HostProtocolEndpoint.
Since vSphere API 6.0 |
queueDepth* | xsd:int |
The queue depth of SCSI device.
|
revision* | xsd:string |
The revision of the SCSI device.
|
scsiLevel* | xsd:int |
The SCSI level of the SCSI device.
|
serialNumber* | xsd:string |
The serial number of the SCSI device.
For a device that is SCSI-3 compliant, this property is derived
from page 80h of the Vital Product Data (VPD), as defined by the
SCSI-3 Primary Commands (SPC-3) spec. Not all SCSI-3 compliant
devices provide this information. For devices that are not
SCSI-3 compliant, this property is not defined.
|
standardInquiry* | xsd:byte[] |
Standard Inquiry payload.
For a SCSI-3 compliant device this property is derived from the
standard inquiry data. For devices that are not SCSI-3 compliant this
property is not defined.
Since VI API 2.5 |
uuid | xsd:string |
Universally unique identifier for the LUN used to identify ScsiLun across
multiple servers.
This identifier can be used to identify analogous objects in other views such as HostMultipathInfoLogicalUnit and HostScsiTopologyLun. |
vendor* | xsd:string |
The vendor of the SCSI device.
|
vStorageSupport* | xsd:string |
vStorage hardware acceleration support status. This property
represents storage acceleration provided by the SCSI logical unit.
See ScsiLunVStorageSupportStatus for valid values.
If a storage device supports hardware acceleration, the ESX host can offload specific virtual machine management operations to the storage device. With hardware assistance, the host performs storage operations faster and consumes less CPU, memory, and storage fabric bandwidth. For vSphere 4.0 or earlier hosts, this value will be unset. Since vSphere API 4.1 |
