1 Overview of HP StorageWorks XP Performance Monitor Performance Monitor lets you obtain usage statistics about physical hard disk drive, volumes, processors or other resources in your storage system. Performance Monitor also lets you obtain statistics about workloads on disk drives and traffic between hosts and the storage system. The Auto LUN window displays a line graph that indicates changes in the usage rates, workloads, or traffic.
Figure 1 Performance Management Process Flow Diagram Auto LUN lets you balance workload among hard disk drives, volumes (LUs) and processors to remove bottlenecks from your system. If Performance Monitor indicates that a lot of I/Os are made to some hard disk drives, you can use Auto LUN to distribute workloads to other disk drives. For details, see the HP StorageWorks XP24000 Auto LUN Software User's Guide.
2 About Performance Monitor Components To use Performance Monitor, you need: • the storage system • the Performance Monitor program products (Performance Monitor is required. Auto LUN is optional) • a WWW client computer connected to the storage system via LAN To use Performance Monitor, you must use the WWW client computer to log on to the SVP. When you are logged on, the HP StorageWorks XP Remote Web Console program, which is a Java application program, will be downloaded to the WWW client computer.
All the statistics that can be monitored by Performance Monitor are collected and stored in short range. • Storing in long range Performance Monitor collects statistics at fixed 15-minutes interval, and stores them for 3 months (that is, 93 days). The usage statistics about resources in the storage system are collected and stored also in long range, in parallel with in short range. However, some of the usage statistics about resources cannot be collected in long range.
When you use External Storage to map the volumes in the external storage system as volumes in the storage system, the mapped volumes in the external storage system are called external volumes. These external volumes are registered in groups by External Storage. Performance Monitor can monitor the usage conditions for external volume groups. Note: An external volume group is just a group for managing external volumes. Unlike a parity group, it does not contain any parity information.

that DRR usage is not balanced, you should consider relocating volumes using Auto LUN to balance DRR usage within the storage system. For details on how to view usage statistics on DRRs, see “Viewing Usage Statistics about Data Recovery and Reconstruction Processors (DRRs)” on page 57. Write Pending Rate and Cache Memory Usage Statistics The write pending rate indicates the ratio of write-pending data to the cache memory capacity.
can also monitor the access workloads of the external volume groups and the external volumes. Performance Monitor displays a line graph that indicates changes in access workloads, so that you can detect the peak I/O access times. Note: You will be unable to view workload statistics that expired a specific storing period because such statistics are erased from the storage system.
8 hours to 15 days) and that changes depending on the collecting interval specified by the user. For details on the storing period of statistics, see “Understanding Statistical Storage Ranges” on page 15. Overview of Export Tool The Export Tool enables you to export monitoring data (that is, statistics) that can display in the Auto LUN window to text files.
• User types If the user type of your user ID is storage partition administrator, the functions you can use are limited. For details, see “Storage Partition Administrators Limitations” on page 25. • Powering off the storage system If you power off the storage system during monitoring, monitoring stops only while the storage system is powered off. When you power on the storage system again, Performance Monitor cannot display the monitoring data while the storage system is powered off.

Preparing for Performance Monitor Operations
4 Using the Performance Monitor GUI Using the Performance Monitor Windows This chapter describes Auto LUN windows and operations. This chapter explains in the following order: each window of Performance Monitor, the procedure for starting and stopping monitoring, and various operation about obtaining and viewing statistics such as resource usage. Caution: If the user type of your user ID is storage partition administrator, the functions you can use are limited.
Figure 5 The Physical Tab of the Auto LUN Window When the Physical tab is active, the Auto LUN window contains the following items: • When Monitoring Switch is Enable, Performance Monitor is monitoring the storage system (a Disable setting indicates that the storage system is not being monitored). • Gathering Interval indicates the interval of collecting statistics in short range monitoring. For example, if the numbers of the CUs to be monitored are 64 or less, and 1 min.
Figure 6 The Drop-Down List to Select Storing Period of Statistics (Physical Tab) The storing period of statistics is the range of monitoring data (statistics collected by monitoring) that can be displayed. You can specify a part of term within the selected range to narrow the statistics to be displayed in the list and graph on the Auto LUN window.
* an ESCON channel adapter * a FICON channel adapter * a Fibre Channel adapter in Standard mode * a Fibre Channel adapter in High Speed mode * a Fibre Channel adapter in Initiator/External MIX mode * The channel adapter number and number of ports that displayed on the right side of the icon are examples.
Note: When you select the parity group icon and the list displays the icon of concatenated parity groups, the list only displays the ID of the parity group at the top of the concatenated parity groups. Figure 7 List of Disk Adapters For details on the list contents, see “Monitoring Resources in the Storage System” on page 50. • The Auto LUN button starts the Auto LUN if that program is enabled and longrange is specified for the display range. Auto LUN lets you optimize hard disk drive performance.
When you select Long-Range Storage The Auto LUN window displays the statistics collected and stored in long range. The usage statistics about resources for three months (that is, 93 days) collected every 15 minutes can be displayed in the window. When you select longrange, the Auto LUN button is activated. The system administrator can start Auto LUN to migrate volumes for balancing workloads based on the monitoring results displayed in the Auto LUN window.
Figure 9 The LDEV Tab of the Auto LUN Window When the LDEV tab is active, the Auto LUN window contains the following items: • When Monitoring Switch is Enable, Performance Monitor is monitoring the storage system (a Disable setting indicates that the system is not being monitored). • Gathering Interval displays a number between 1 and 15 to indicate how often data collection is performed.
When you specify dates and time in From and To boxes, Performance Monitor calculates the length (in minutes) of the specified period and displays the calculated length. When calculating the length in minutes, Performance Monitor rounds up to the nearest minute. Notes: • The From and To boxes are grayed out if the monitoring data (that is, obtained statistics) is not stored in the storage system. • The Real Time option is grayed out when the LDEV tab is active.
If you select connected parity groups in the tree, the list displays statistics about disk access performance for all the connected parity groups. Note: When you select a folder icon such as Box 1 or Box 3, the concatenated parity group icon is displayed in a list. The only parity group ID displayed will be that of the group at the top of the concatenated parity groups. The icon used for concatenated parity groups is the same as a regular parity group icon.
When you draw a graph, use the Detail check box to illustrate the desired information and the Chart Y Axis Rate drop-down list to arrange the graph as you like. Figure 11 Chart Y Axis Rate Drop-Down List and Detail Check Box (LDEV Tab) The Chart Y Axis Rate drop-down list lets you select the highest value of the Y-axis (the vertical axis) of the graph. If you select the Detail check box and then the Draw button, the graph displays detailed statistics as explained in Table 5 on page 38.
Figure 12 The Port-LUN tab of the Auto LUN Window When the Port-LUN tab is active, the Auto LUN window contains the following items: • When Monitoring Switch is Enable, Performance Monitor is monitoring the storage system (a Disable setting indicates that the system is not being monitored). • Gathering Interval indicates that the statistics are collected at the interval displayed here.
• The Real Time option lets you view statistics in real-time mode, where statistics are updated at a gathering interval you specify between 1 and 15 minutes. When you select the Real Time option, use the drop-down list to select the number of recent collections of statistics which should be displayed in the graph. You can select the number of times from 5 or 90. This setting determines the range of recent statistics to be displayed in the graph. For example, suppose the gathering interval is 1 minute.
Figure 13 Chart Y Axis Rate Drop-Down List, Detail Check Box, and the Drop-Down List to Select the Item to be Displayed (Port-LUN Tab) The Chart Y Axis Rate drop-down list lets you select the highest value of the Y-axis (the vertical axis) of the graph. If you select the Detail check box after drawing a graph by selecting the Draw button, the graph displays detailed statistics as explained.

Figure 17 The Monitoring Options Window of Performance Monitor The Monitoring Switch area in the Monitoring Options window contains the following items: • Current Status To start obtaining statistics of the storage system (that is, monitoring), select Enable. To stop monitoring, select Disable. The default setting is Disable. • Gathering Interval Specify the interval to obtain usage statistics about the storage system for short range monitoring.
• LDKC list: indicates LDKC numbers. To select an LDKC as a monitoring target, click the LDKC number. All the CUs that belong to that LDKC are displayed. • CU table: The CU table consists of cells representing CUs. Each row consists of 16 cells (CUs). A set of 16 rows represents CUs for one LDKC. The table header row displays the last digit of each CU number in the form of +n (n is an integer between 0 and 9, or a letter from A to F). To select a CU, click a cell to invert its color.
one minute for the gathering interval, the statistics for one day can be stored at the maximum from the following formula: 1 minute x 1440 = 1440 minutes = 24 hours = 1 day This storing period is the range of display in the Auto LUN windows. When you specify one minute for the gathering interval like the example above, Performance Monitor can display the statistics for one day (that is, 24 hours) in the list and graph at the maximum.
Using the Performance Monitor GUI
5 Performance Monitor Operations Overview of Performance Monitor Operations This section briefly describes how to use Performance Monitor to monitor the storage system. Start Monitoring To start monitoring the storage system, you start Performance Monitor and display the Monitoring Options window (Figure 18 on page 47).
Moreover, the resource usage in the storage system can also be stored in a long range up to 3 months. In this case, however, the gathering interval is fixed to 15 minutes regardless of the value set for the Gathering Interval option. For details on the relationship of collection interval and storing period of the statistics, see “Monitoring Options Window” on page 42.
Enables you to view statistics about traffic at path between host bus adapters (HBAs) and ports (see “Traffic between HBAs and Storage System Ports” on page). Two sliders are displayed on the upper right of the Auto LUN window. To the left and right of the two sliders, dates and times are displayed. The term between these dates and times is the period in which statistics are stored.
6. Select Apply. Performance Monitor starts monitoring the storage system. Note: When statistics are collected, a heavy workload is likely to be placed on servers. Therefore, the client processing might slow down. To stop monitoring the storage system: 1. Start Performance Monitor and select the Monitoring Options tab. The Monitoring Options window is displayed (see Figure 17 on page 43). 2. In Monitoring Switch, select Disable for the Current Status option.
Note: It is possible that the usage rate for a parity group is not equal to the sum of the usage rate for each volume in that parity group (see “Viewing Usage Statistics about Volumes in Parity Groups” on page 51). This is because the Auto LUN window rounds off fractions below the decimal point to the nearest whole number when displaying the usage rate for each volume. Note: If there is no volume in a parity group, hyphens (-) are displayed in place of performance statistics on a parity group.
The list on the right displays usage statistics about volumes in the specified parity group (Figure 21 on page 52). The displayed statistics are the average and the maximum usage rates for the period specified in the From and To boxes. Notes: • If you change the date and time in the From and To boxes and then click the Apply button, Performance Monitor recalculates usage rates and updates information in the list.
• • • • • The Rnd. column indicates random read rates. A random read rate is the ratio of random read requests to read and write requests. • The Seq. column indicates sequential read rates. A sequential read rate is the ratio of sequential read requests to read and write requests. Write Rate: • The Rnd. column indicates random write rates. A random write rate is the ratio of random write requests to read and write requests. • The Seq. column indicates sequential write rates.
5. • If you change the date and time in the From and To boxes and then click the Apply button, Performance Monitor recalculates usage rates and updates information in the list.

This section describes how to view the statistics about disk access performance. Before taking the following s, you need to start monitoring in accordance with the procedure described in “Starting and Stopping Storage System Monitoring” on page 49 and obtain the usage statistics. Viewing I/O Rates for Disks Performance Monitor monitors hard disk drives and measures I/O rates (that is, the number of disk I/Os per second). To view I/O rates: 1. Ensure that the Auto LUN window is displayed. 2.
I/O rate for parity groups and external volume groups (When the Subsystem folder is selected): I/O rate for parity groups or external volume groups (When the Box 1 folder is selected): I/O rate for volumes: Note: It is possible that the I/O rate for a parity group or an external volume group is not equal to the sum of the I/O rate for each volume in that group. This is because the Auto LUN window omits fractions below the decimal point when displaying the I/O rate for each volume.
• CLPR: This column indicates numbers and names of CLPRs corresponding to each parity group, external volume group, or volume in the format CLPR-number:CLPR-name. For details on CLPRs, see HP StorageWorks XP24000 Disk/Cache Partition User’s Guide. Viewing Transfer Rates for Disks Performance Monitor monitors hard disk drives and measures transfer rates (that is, the size of data transferred in one second). To view transfer rates: 1. Ensure that the Auto LUN window is displayed. 2.
Transfer rate for parity groups and external volume groups (When the Subsystem folder is selected): Transfer rate for parity groups or external volume groups (When the Box 1 folder is selected): Transfer rate for volumes: Note: It is possible that the transfer rate for a parity group or an external volume group is not equal to the sum of the transfer rate for each volume in that group.
Monitoring Ports Performance Monitor monitors ports on the storage system and measures I/O rates (that is, the number of I/Os per second) and transfer rates (that is, the size of data transferred per second). This section describes how to view I/O rates and transfer rates of ports on the storage system. Before taking the following s, you need to start monitoring in accordance with the procedure described in “Starting and Stopping Storage System Monitoring” on page 49 and obtain the usage statistics.
I/O rate for ports (When the Subsystem folder is selected): All Prio. indicates all the prioritized ports. All Non-Prio.
• Peak: Indicates the peak I/O rate of the ports for the specified period. This value is shown in the list when you select the Subsystem folder in the tree. If you select a port in the list, click the Draw button, and select the Detail check box, the detailed graph of the port I/O rate is drawn. The Peak value means the top of the Max. line in this graph. • Max.: Indicates the maximum I/O rate for the specified period. This value is shown in the list when you select a port icon or host group icon in the tree.
Transfer rate for ports (When the Subsystem folder is selected): All Prio. indicates all the prioritized ports. All Non-Prio. indicates all the non-prioritized ports.
• Max.: Indicates the maximum transfer rate for the specified period. This value is shown in the list when you select a port icon or host group icon in the tree. • Response Time: This column indicates the time for replying from the port or host bus adapter when I/O accesses are made from the host to them. The unit is milliseconds. The average response time in the period specified at Monitoring Term is displayed. Note: This column displays a hyphen (-) if the I/O rate is 0 (zero).
7. To display a graph to find out how the I/O rate has been changed, take the following steps; a. In the list, select one or more LUNs. b. Select the Draw button. Note: If the graph does not display changes in the I/O rate (for example, if the line in the graph runs vertically), it is recommended that you change the value in the Chart Y Axis Rate drop-down list.
5. In the tree, double-click a port (for example, or ) and then select a host group ( ). The LUN icon ( ) appears. 6. Select LUN. The list on the right displays a list of LU paths and transfer rates (Figure 35 on page 72). 7. To display a graph to find out how the transfer rate has been changed, take the following steps; a. In the list, select one or more LUNs. b. Click the Draw button.
6 Using the Export Tool Files to be Exported The Export Tool enables you to save monitoring data in the Auto LUN window into files (see Table 11 on page 74 through Table 18 on page 81). The Export Tool also enables you to save monitoring data about remote copy operations into files (see Table 19 on page 82 through Table 26 on page 87). The Export Tool usually compresses monitoring data in ZIP files.
