4. To find out how traffic has changed, click the ports, WWNs, or LUNs, and click Draw. A graph
appears below the table.
5. To view more detailed information in the graph, click the Detail check box on the lower-right side of the
table, and click Draw. The graph contents change.
The table displays the following:
• Graph column: The check mark icon indicates the graph is currently illustrating data for that item.
• Port: Ports on the disk array.
• WWN: WWNs of the host bus adapters.
• LUN: LUNs (logical unit numbers).
• PFC Name: PFC names of host bus adapters.
• Nickname: Nickname for host bus adapters. LUN Manager allows you to assign a nickname to each
host bus adapter so you can easily identify each host bus adapter in the LUN Manager panes.
• CU:LDEV: Logical volume IDs. The number on the left of the colon is the CU image number. The number
on the right of the colon is the LDEV number. If a logical volume ID ends with the symbol #, the logical
volume is an external LU.
• Emulation: Emulation types.
• Paths: Number of LU paths.
• Current: Current I/O rate.
• Ave.: Average I/O rate for the specified period.
• Max.: Maximum I/O rate for the specified period.
• Response Time (ms): Time (in milliseconds) for replying from an external volume group when I/O
accesses are made from disk array to external volume group. Average response time in the period
specified for Monitoring Term is displayed.
If you select a port in the list, click Draw, and select the Detail check box, a detailed graph of the port
I/O rate is drawn. The Peak value means the top of the Max. line in this graph.
• Attribute: Priority of each port. Prio. indicates a prioritized port. Non-Prio. indicates a non-prioritized
port. iSCSI ports are always prioritized ports. Therefore, the Attribute column displays Prio. for each
