Linkable identifier.
Identifier of LogicalUnit.
Use this id to configure LogicalUnit multipathing policy using SetMultipathLunPolicy.
The ScsiLun data object describes a SCSI logical unit.
A SCSI logical unit is a host device that an ESX Server or virtual machine can use for I/O operations.
An ESX Server creates SCSI logical unit objects to represent devices in the host configuration. (See the definition of ScsiLunTypeEnum 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.
- Disks containing file system volumes or parts of volumes for hosts or raw disks for virtual machines. To represent disks, the ESX Server creates a HostScsiDisk object, which inherits properties from the ScsiLun base class.
- Other SCSI devices, for example SCSI passthrough devices for virtual machines. To represent one of these devices, the ESX Server creates a ScsiLun object.
When the Server creates a HostScsiDisk or ScsiLun object, it specifies a valid device name and type:
- deviceName - A string representing the name of the device that is meaningful to the host. The following are some examples of device names.
/dev/cdrom
/vmkdev/vmhba0:0:1:0
PhysicalDrive0
- deviceType - A string describing the type of device. The following are some examples of device types.
scsi-cdrom
scsi-tape
scsi-disk
scsi-processor
scsi-unknown
The HostMultipathInfoLogicalUnitPolicy data object describes a path selection policy for a device.
This policy determines how paths should be utilized when accessing a device.
The HostMultipathInfoLogicalUnitStorageArrayTypePolicy data object describes a storage array type policy for for a device.
This policy determines how device I/O and management is performed.
