Running HP P6000 Performance Data Collector 1. Double-click the HP P6000 Performance Data Collector icon on the desktop. The HP P6000 Performance Data Collector command window opens. 2. Enter the following command to capture and display the total IOPS (Req/s) and throughput (MB/s), where n is the interval in seconds and m is the duration in seconds: evaperf as -cont n -dur m -sz array -fo filename Specify an interval and duration that will enable you to view a period of low I/O activity. For example, collect data once every 10 minutes for a period of 6 hours when you plan to do the upgrade to familiarize yourself with characteristic I/O and throughput values. For example, the following command will capture data at 10-minute intervals (60*10) for 6 hours (60*60*6) on an array named EVA1, and store the output in a file named EVA_upgrade: evaperf as -cont 600 -dur 21600 -sz EVA1 -fo C:\EVA_upgrade You can store the data in a folder or drive of your choice. (To see your own friendly names, run HP P6000 Performance Data Collector with the fnh command and list the names with the ls command.) 3. Identify instances where IOPS are at a minimum as periods to consider for performing the upgrade. The following configurations and performance levels have been validated by HP for online upgrade of controller software and disk drive firmware. All configurations include the use of HP P6000 Continuous Access.

See the HP P6000 Command View User Guide for more information. NOTE: If you have P6000 Performance Advisor licensed and installed, see HP P6000 Performance Advisor User Guide for more information. Identifying virtual disk activity If you cannot identify a period that meets the necessary I/O load requirements, identify those applications that impose heavy I/O loads, and suspend them long enough to perform the upgrade. To do this, use HP P6000 Performance Data Collector to view virtual disk activity. For example, after running HP P6000 Performance Data Collector, you determine that all virtual disks on the array are nearly idle except for one virtual disk. To perform an online upgrade, halt the application that is imposing the load on the busy virtual disk. This will be far less disruptive to your environment than performing an offline upgrade. To view virtual disk activity: 1. Double-click the HP P6000 Performance Data Collector icon on the desktop. The HP P6000 Performance Data Collector command window opens.
