60 Auto LUN/Performance Control Base Monitor
• To view traffic statistics about host ports in a host group, click the host group.
Figure 32 Traffic statistics about host ports in a host group
• To view traffic statistics about LU paths, click the LUN icon.
Figure 33 Traffic statistics about LU paths
NOTE: The traffic statistics reported for an LU is aggregated across all LU paths defined for an LU.
• I/O rate is the sum of I/Os across all LU paths defined for an LU.
• Transfer rate is the total transfer rate across all LU paths defined for an LU.
• Response time is the average response time across all LU paths defined for an LU.
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 microseconds) 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. When calculating I/O rates to be displayed in the All Prio. row, Auto LUN XP uses I/O rates of
other prioritized ports.
