Creating and Managing VTLs and VTDs | 31
Property Description Presented
to Host?
Target ID The SCSI ID on which the VTD responds. This ID is not
presented to the host if the connection is over Fibre Channel.
Yes, for
SCSI only
Logical unit
number (LUN)
The sub-ID on the port. This ID is used by the host for SCSI
and Fibre Channel connections.
Yes
Serial number The serial number or other string describing the VTD. Only
alphanumeric characters should be used.
Yes
The port ID, target ID, LUN, and initiator ID (not shown) are collectively referred to as the PTLI. The
PTLI enables the host server to precisely identify the VTD; it provides an exact address of the VTD
on the port. Remember that the host is connected to VTS by a single cable. The PTLI thereby enables
you to multiplex the cable to identify multiple VTDs over a single cable (for Fibre Channel VTDs).
Before beginning
l Enable Managed Capacity or VTD licensing as described in Enabling Licensed Features, if
necessary.
l Verify that at least one port is set to Virtual (target) mode on the Configure Virtual Devices
page. Ports should have been configured as described in "Configuring Ports" on page 23.
l You may want to stop VTDs that use the same port as the one you will create. Creating a VTD
may interrupt the activities of other VTDs on the same port.
l Back up the VTS database before modifying the VTS configuration. See "Backing up the VTS
server" on page 155 for more information.
