5. In the Select Volume box, select one of the following:
• ALL Volumes, to view I/O statistics for all LDEVs in the system. When selected, the LDKC
number, CU number, and LDEV number appear above the graph.
- A device ID ending in # (e.g., 00:00:3F #) indicates the LDEV is an external volume.
For more information, see the HP P9000 External Storage for Open and Mainframe
