External Storage XP user guide 57
• Total number of Devices: Number of external LUs that are connected.
• Total number of External Groups: Number of external LU groups that are set.
• Total number of External LUs: Number of external LUs that are connected.
• Found WWNs: WWNs found when you clicked Discovery in the Device tree.
• Remain LUs: Number of external LU numbers available (out of 15,360), other than those that have
already been used.
• WWN Entry: Number of LUs that are currently used in the external array out of the maximum
theoretically possible (15,360).
Displayed in the format The number of connected ports/16,384 (the number of ports which can be
connected).
• Total number of WWNs: Number of external array ports that are connected.
• Total number of Paths: Number of paths set between the local array and external array.
• Preset list
Displays the contents of settings that were set by operations started on the LU Operation pane.
Contents displayed in the Preset list have not yet been applied to the local array. They are applied
when you click Apply. For more information, see ”Preset list (LU Operation pane)” on page 66.
• Operation information area
Displays operation information about settings in the Preset list, including:
• Operation: Setting operation name.
• Number of Objects in Preset: Number of rows displayed in the Preset list.
• Apply button
Applies pending operations in the Preset list to the local array. When operations are applied
successfully, they are removed from the Preset list. Otherwise, error messages appear and error
settings remain in the Preset list.
• Cancel button
Cancels all settings in the Preset list.
Device tree
Displays information about the external array connected to the external port.
Figure 29 Device tree
The Device list (right pane) changes according to the item selected in the Device tree.
• Subsystem
When selected, displays nothing in the Device list and displays the External Devices branch of the tree.
Subsystem is selected when you start External Storage XP and display the Device tree.
• External Devices
When selected, the Device list displays information about external arrays connected to external ports
that have been detected (supported).
NOTE: Not all types of detected external arrays are supported.
• Product name of the connected external array
