58 External Storage XP panes
Displays the name of the external array that can be connected using External Storage XP in the tree
under External Devices. When you select an external array’s product name, the Device list displays
detailed product information.
• External LU group number
Displays user-assigned numbers in the branch under the external array’s product name, which is
connected to the local array and is already used. When you select an external LU group number, the
Device list displays information about external LUs registered in the selected group.
• Discovery
Appears in the branch under the product name of the external array connected to the local array.
When selected, External Storage XP searches for external array ports that can be connected, and
displays their WWNs.
• WWN of the external array
If you select the WWN found by selecting Discovery in the Device tree, the Device list displays
information about external LUs that can be connected from the port indicated by the WWN.
Device list
Displays information about external arrays corresponding to the item selected in the Device tree. You can
sort the list by displayed items. For example, to sort by LUN numbers, click LUN in the list.
When performing setting operations, the settings appear in the Preset list and the corresponding row in
the Device list appears in blue italics. For more information, see ”Preset list (LU Operation pane)” on
page 66.
Figure 30 Device list (external device selected in Device tree)
• Subsystem
Displays nothing. Subsystem is automatically selected when you select the Device tree.
• External Devices (for example, external storage group numbers currently defined for that external
device)
• Serial: Product serial number.
• Product: Product name.
• Vendor: Vendor name.
• Ex-Dev. Status: Status of the operation executed to the external array, or status of path connection.
External array’s status. Possible values: Normal, Unknown, Blockade, Warning, Checking, Cache
Destage, and Disconnect.
Table 8 External array status values
LU status Description
Normal LU status is normal.
Unknown LU status has yet to be ascertained.
Blockade I/O traffic to the LU is not permitted.
