Viewing LUSE configuration information
• The LDEV Information tree displays an outline view of the CU and LDEV numbers installed on the disk
array in a hierarchical structure.
• The LDEV Information table displays detailed information for all open system LDEVs in the selected CU.
If you select a normal LDEV, the information in this section is for the top LDEV. If you select a LUSE
volume, the information in this table is for all of the LDEVs in the LUSE volume.
An LDEV number that ends with a # indicates that the LDEV is an external LU (for example, 00:01#).

Information table displays all the LDEVs in the selected CU.
