If the following performance problems occur in the SVP, collect the performance information of the SVP and dumps using the performance information collection tool, and then send them to the maintenance personnel:
- Slow operation of the SVP
- High CPU usage rate of the SVP
- Slow operation of the Storage Device List or the Device Manager - Storage Navigator
CAUTION:
The tool used in this procedure collects the performance information of the SVP. This tool is installed in the directories corresponding to the serial numbers of all storage systems registered in the Storage Device List. Although this tool does not collect performance information of individual storage systems, it can collect dump files for the storage system corresponding to the directory used to run the tool. Therefore, for the storage systems other than that storage system, see
Downloading dump files and
Collecting dump files manually to collect the dump files, and then pass them to maintenance personnel.
Use the following procedure to collect performance information of the SVP by using the performance information collection tool. Collection of performance information takes about 30 minutes, and then the dump files are automatically collected.
- Any performance problem of the SVP must be occurring.
- You must be logged into the SVP.
- Device Manager - Storage Navigator must be running.
- All other users (including the SVP user) must stop using the performance information collection tool.
- All maintenance operations must be stopped.
- Performance information collection tools from other storage systems must not be used during the process.
- The installation directory of the Device Manager - Storage Navigator must be excluded from the real time virus scan targets
by the virus detection program.
For the virus detection program settings, see Preventing errors while using virus detection programs on the SVP.
Note: If the error is in regards to Device Manager - Storage Navigator starting up, collect information about the SVP using the performance information collection tool without Device Manager - Storage Navigator running. If some tools are running, performance of the SVP might be further degraded.
-
On the SVP, open a command prompt window with administrator permissions.
- Move the current directory to the directory in which the tools are installed.
For example, if the model identification number of the storage system is 932000400001, the directory in which the tool is installed is C:\Mapp\wk\932000400001\DKC200\mp\pc. In this case, enter the following:
cd /d C:\Mapp\wk\932000400001\DKC200\mp\pc
Note: C:\MAPP indicates the installation directory of the storage management software and the SVP software. When the installation directory other than C:\Mapp was specified, replace C:\Mapp with the specified installation directory.
-
Run the performance information collection tool
GetSVPPerfInfo.bat by specifying the output folder of
the performance information and dump files. In the command prompt, enter the
following:
GetSVPInfo.bat output-directory
For example, when you want to output the performance information and dump files of the SVP to C:\Result_932000400001, enter the following command:
GetSVPPerfInfo.bat C:\Result_932000400001
If you do not specify output directory, the performance information and dump
files are output to the following folders:
C:\Mapp\wk\932000400001\DKC200\tmp\PerfLog
C:\Mapp\wk\932000400001\DKC200\tmp\PerfLog
In this example, 932000400001 is the model identification number of the registered storage system.
Note:
- When you enter the command, a space is required between the .bat file of the tool and the output directory.
- A directory under the network drive cannot be specified as the
output destination.
- Do not click or close the command prompt window while running the
tool.
- When the tool is being executed, Executing… is displayed in the command prompt.
- The tool automatically starts collecting dumps after collection of the performance information finishes.
- Both performance information and system information of the SVP are collected. Do not click Cancel on the dialog box that opens while system information is collected. The dialog box closes automatically after collection of system information finishes.
- When all processes are complete, SVP Performance Information tool is completed. is displayed in the command prompt.
-
Check the dump files that were output.
The following files are output:
- CounterResult_YYYYMMDDhhmmss.blg：Windows performance monitor log
- ProcessList_YYYYMMDDhhmmss.csv：Information of the processes running on the SVP
- Sysinfo_YYYYMMDDhhmmss.txt：System information of the SVP
- hdcp.tgz
- zSv_AutoDump.log
- DumpResult.txt
-
Close the command prompt.
- An OS failure might cause a failure of collecting dumps. If the output result of the tool in step 4 is not output, collect the dump files manually.
- Send all of the files that were output to the maintenance personnel.
