Show ITLs dialog box
This dialog box shows a read-only list of Initiator-Target-LUN combinations that shows the storage volume's back-end path
(metro node back-end port, storage port, and LUN). you can also search for a specific initiator, target or LUN by entering the
number in the Find text box and pressing Enter.
The following table describes the fields shown in the dialog box:
Field/Column Description
Storage Volume Name The name of the selected storage volume.
System ID The array's ID number for the storage volume.
Initiator The Port WWN of the metro node backend port.
Target The Port WWN of the storage array target port.
LUN The Logical Unit Number for the storage volume.
Logical unit properties
Name The VPD identifier for the logical unit.
Active AAO
Controller
The active (or ALUA optimized) controller for the logical unit.
Active AAO
Visibility
Lists all directors that have a path to the active (or ALUA optimized) controller for this logical unit.
Passive AAN
Controller
The passive (or ALUA non-optimized) controller for the logical unit.
Passive AAN
Visibility
Lists all directors that have a path to the passive (or ALUA non-optimized) controller for this logical unit.
LUNs The LUN number on the array.
Storage Volume The storage volume to which this logical unit belongs.
ALUA Support Indicates if Asymmetrical Logical Unit Access (ALUA) is supported on the array. Depending on the type of
controller exposed to the LUN, one of these values will display. Possible values:
Implicit The logical unit can change its ALUA access state internally within the array without any external input
requesting a change.
Explicit The logical unit can change its ALUA access state in response to a request from an initiator (metro node back
end software).
Implicit explicit The logical unit has both implicit and explicit capabilities.
None ALUA is not supported on the array.
Connectivity
Status
The connectivity status of the logical unit.
Visibility Indicates how the logical unit is visible to the controllers. Possible values:
Active optimized All commands and task management functions can be sent on this path; this path has the highest
performance (ALUA arrays only).
Active non-optimized All commands and task management functions can be sent on this path, but the path has a
lower performance than an active optimized path (ALUA arrays only).
Active The controller actively processing I/O requests.
Both Both controllers process I/O and provide standby capability for each other. One controller is actively processing I/O
while the other is idle in standby mode waiting to process I/O should the active primary controller fail or be taken offline.
None ALUA is not supported on the array.
