A XP Performance Control Export Tool
This appendix provides additional instructions for using the XP Performance Control Export Tool.
This appendix makes the following assumptions:
• You have a background in data processing and understand arrays and their basic functions.
• You are familiar with XP Command View Advanced Edition or Remote Web Console.
• You have read and understand the HP StorageWorks XP Command View Advanced Edition software
Device Manager user guide or the HP StorageWorks XP Remote Web Console user guide for the
specific array.
• You are familiar with the operating system (for example, Windows® and Solaris®) and web browser
software (for example, Internet Explorer and Netscape) on the system hosting the XP Command View
Advanced Edition or Remote Web Console software.
Overview of XP Auto LUN
You can use XP Auto LUN to monitor and tune array performance. Its major components are:
• HP XP Auto LUN
• HP XP Performance Control (henceforth, referred to as PFC)
You can use XP Auto LUN to obtain usage statistics about physical hard disk drives, logical volumes,
processors, or other resources in your array. You can also obtain statistics about workloads on disk drives
and traffic between hosts and the array. The XP Auto LUN pane displays a line graph indicating changes
in the usage rates, workloads, or traffic. You can view information in the pane, analyze trends in disk
I/Os, and detect peak I/O time. If the system performance is low, you can use information in the pane to
detect bottlenecks in the system.
You can use XP Auto LUN to balance the workload among hard disk drives, logical volumes, and
processors to remove bottlenecks from your system. If XP Auto LUN indicates that a large number of I/O
operations are made to some hard disk drives, you can use XP Auto LUN to distribute workloads to other
disk drives.
For more information about XP Auto LUN, see the HP StorageWorks XP Auto LUN user guide for the
specific array. For more information about XP Performance Control, see ” XP Performance Control ” on
page 7.
Exporting monitoring data to files
Use the Export Tool to export monitoring data (statistics) displayed in the XP Auto LUN pane to text files.
You can also use the Export Tool to export monitoring data on remote copy operations performed by XP
Continuous Access, TrueCopy for z/OS
®
, XP Continuous Access Journal, and Universal Replicator for
z/OS. Once you export the monitoring data to text files, you can import it into word processor
documents. You can also import the monitoring data into spreadsheet or database software for analysis.
