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
