SetWTDiskLunMapping method of the WT_Host class

Sets the SCSI Logical Unit Number (LUN) number of the specified virtual disk.

Syntax

void SetWTDiskLunMapping(
  [in] uint32 WTD,
  [in] uint32 LUN
);

Parameters

WTD [in]

The iSCSI disk index for the virtual disk.

LUN [in]

The SCSI LUN number.

Return value

This method does not return a value.

Remarks

Each virtual disk within an iSCSI target has a unique Logical Unit Number (LUN). The uniqueness is only per iSCSI target. A virtual disk may have different LUNs if it is assigned to multiple iSCSI targets.

When a virtual disk is assigned to an iSCSI target, the LUN is determined automatically. Use this method only if you need to specify a LUN.

In order for an initiator to access a virtual disk over an iSCSI Storage Area Network (SAN), the virtual disk should be assigned to a WT_Host object that is configured to allow the initiator access to the LUNs that the virtual disk contains.
