Collecting NAR Files or Performing a CLARiiON or VNX Storage Array Profile

Team Live Optics

Overview

Live Optics supports the profiling of several hardware storage arrays.  One of these is the Dell EMC CLARiiON and VNX families.  Using the Live Optics collector, configuration and performance data is captured, analyzed and compiled into a Project for viewing.  This document outlines the process to produce a CLARiiON and VNX array storage profiles.

Pre-Requisites

Before the Live Optics array profile is executed, the array configuration and performance data needs to be gathered using the storage array management interfaces.  Performance data is stored on the array in .NAR (or sometimes .NAZ) files.  Configuration data is collected by executing a process called SPCollect which generates a compressed (.zip) file.  Both the SPCollect and NAR files are needed to perform the profile.  Collect these files and place them in a folder. 

NOTE:  At this time, NAZ files are not accepted by Live Optics to create a CLARiiON/VNX project.  NAZ files should be sent in to Live Optics Support to generate their NAR files prior to uploading to Live Optics.

Quick-Start Directions

  1. Launch Live Optics Collector (Windows .NET version)
  2. Click Get Started
  3. Click “Yes, I agree” to accept the End User License Agreement (prompted only on first execution)
  4. Click “Yes, this is me” after verifying your identity is correct (prompted only on first execution)
  5. Select Storage from the left menu
  6. Select CLARiiON/VNX
  7. Click Select Folder, browse to folder with NAR files, click OK
  8. Click Next
  9. Click Browse for File, browse and select the SPCollect zip file, click Open
  10. Click Next
  11. Select the Upload Option, either upload automatically (recommended) or upload later
  12. Click Next
  13. If upload automatically was selected, enter the project name to be created, click Next
  14. After the files are processed and optionally uploaded, click Quit to exit the application

Detailed Instructions

Step 1: Download the Live Optics Windows collector software

  • There are two methods to download the collector software.
    • One: From the email you received from your systems consultant inviting you to Live Optics by clicking the Download Collector link.
    • Two: From the Live Optics portal, select Collectors from the left menu, then Download Collector.
  • Either option will bring you to the Download Collectors page. To perform storage array profiles, download the Windows collector.  Note, the Windows collector requires .NET 4.5 or greater to be installed on the host running the collector.
  • Click the Download button to start the download. A file named LiveOptics.zip will be downloaded.
  • Once the file download completes, extract the contents of the zip file on the host where you wish to run the software. The Live Optics collector does not install like a typical Windows application.  Extracting the zip file is all that is needed to run the collector.  Note, the collector can be run on any host with IP connectivity to the storage arrays you wish to profile.

 

Step 2: Run Live Optics collector software

  • Open the directory where you extracted the files from the zip download and double-click LiveOpticsDotNet4_5.exe.
  • Click the “Yes, I agree” button to accept the End User License Agreement

Note, this appears the first time you run the collector software. Each subsequent time you will not be asked this question.

  • Confirm your name/company is correct and click “Yes, this is me”. If you were invited to run Live Optics, your systems consultant information will also be listed.
    • Note, this appears the first time you run the collector software. Each subsequent time you will not be asked this question.

Step 3: Select Storage from the list of profile types.

Step 4: Select CLARiiON/VNX from the list of storage array models.

Step 5: Select Files

  • Click Select Folder and browse to the folder where the previously extracted array performance (.NAR) files are located. The collector will automatically scan the folder for files and indicate a count of found files.  Once the files have been selected, click Next.

 Step_5.png

  • Click Browse for File and select the SPCollect zip file from the array. The dialog will default to the same folder of the NAR files.  Note, sometimes two SPCollect files are generated, one for each SP or service processor.  You only need to select one of them.  The information in the files is the same regardless which file is selected.  Once the file has been selected, click Next.

    Step_5_2.png  

Step 6:  Select the method to upload to the Live Optics web site for processing

  • Selecting the default, “Upload my collection data to the Live Optics web portal automatically”, is the recommended method. This option will automatically upload the collected data to the Live Optics portal and start processing. Use this option when the host running the collector has Internet access. Once selected, click Next.

 Step_6.png

  • Enter the name of the project for your array profile. Click Next.Step_6_2.png
  • The files are processed and uploaded to the web portal. During the upload, a status bar indicates the progress.  As storage array data can be quite large, the upload may take some time to complete depending on the speed of your Internet connection.Step_6_3.png
  • The collector will indicate when the upload has completed. Click Quit to close the collector
  • You will receive an email from Live Optics when your project is ready for viewing on the web portal.

 Step_6_4.png

  • Selecting “I will upload later…” will process and save your array data to an encrypted file with the name [hostname]_ClariionVNX.siokit. The file is written to the same folder from where the collector was executed. Use this option when the host running the collector does not have Internet access.

 Step_6_5.png

  • After the collection process completes, the file will need to be uploaded to the web portal for processing using the collector.

Step 7: Uploading the SIOKIT file (applies only if selected “I will upload later…”)

  • The Live Optics web portal supports directly uploading .siokit files that are less than 100MB. If your file is large than 100MB, use the collector to upload the file.  The following outlines the steps for uploading using the Windows collector.
  • Copy the .siokit file along with the downloaded collector files (or download again) to a host with Internet access.
  • Double-click on LiveOpticDotNet4_5.exe to start the collector.
  • From the upper right menu bar, select Upload SIOKIT.Step_7.png
  • Click Browse for File. Select the .siokit file.
  • Enter the name of the project for your array profile. Click Upload.Step_7_2.png
  • The file is uploaded to the web portal. During the upload, a status bar indicates the progress.  As storage array data can be quite large, the upload may take some time to complete depending on the speed of your Internet connection.Step_7_3.png
  • The collector will indicate when the upload has completed. Click Quit to close the collector.
  • You will receive an email from Live Optics when your project is ready for viewing on the web portal.

Step 8: View Project Results

 

  • Log in to the Live Optics web portal (https://www.liveoptics.com)
  • Your recent projects are listed on your dashboard. Select your project.Step_8.png
  • The project details page appears. From here you can download the report in PowerPoint format (PPT), download an Excel file (XLXS) containing all the array details, share your project with other Live Optics users such as your systems consultant, or delete your project.

    This article should be updated to include the procedure to generate and retrieve NAR and SP Collect files.

    Agree with Matias Campo - at a minimum include the KB article from support.emc.com

    NAR and SP Collect files are generated from the Unisphere console.  Registration to EMC Support  is required to view the KB articles regarding the process to avoid update confusion.

    Directions to retrieve the NAR and SPCollect files can be found in the following EMC support article – https://support.emc.com/kb/9132.  Note, a valid login is required to access EMC support site.

    Needs to include file performance info from the DMs as well as pool tier level metrics that Mitrend used to have.

    Also the disk drive heat map, it was very useful to visually identify which disks were overtaxed in the array.

    Hi,

    If collector gives you "No files detected" when you browse for .nar files, make sure file extensions are lowercase "*.nar", not uppercase "*.NAR"
