BVQ installation - questions and answers


One thing to mention!

It is easy to use BVQ - but sometimes it is hard to understand the meanings of performance-view data correctly. We are the specialists who give suppot to understand what you are seeing.
To give you a better start, we offer you to get in contact with us if you need support interpreting your data.

  1. The BVQ server may not be named 'BVQ' - please use xxBVQ instead!

  2. How long does it take to install BVQ?
    The installation normally only takes 1-2 hours. After these 2 hours BVQ can be started.

    After installation you should plan to customize BVQ for the IO density analysis.
    The time for this is very much depending on the complexity of your storage environment.
    Customize BVQ for IO density analysis (This step is not needed for V7000 and V3700)

  3. The scanner doesn't start!
    Are you able to connect to the SVC or Storwize from the BVQ server? (test with Putty)
    Did you setup the statistic collection to 5 minutes?
    (Starting with BVQ 3.x it is also possible to work with 1 minute)

  4. I have problems to install the BVQ license key.
    Some issues may occur if the license key is stored on a network device - please retry with the license key read directly from the BVQ server.

  5. On install BVQ says BVQ license key is invalid.
    In this case you might have a license key which doesn't fit to the actual version you are installing - please send a note to BVQ@SVA.de before you lose time with try and error.

  6. Where do I find the DB download and DB2 license?
    Please download the DB2 version from our prerequisite section. DB2 can be installed in demo mode and will run for several weeks. So it can be used for the BVQ demo install.
    The DB2 license is included in the BVQ software. We will send you this license together with the BVQ full license.

  7. How long does it take to get first data after the installation has finished?
    This depends on the size of your storage system - you can expect the first data 5 to 15 minutes after the scan process has started.

  8. What is the reason for not shown long term indicators in the treemap after the install had been finished?
    The reason is simple - it needs about 7 days to collect data to show a 7 day mean value. So after 7 days of constant data collection you will be able to see all data in BVQ.

  9. What is the reason for a not working IO Heat display in BVQ - it doesn't show any results?
    You need to customize BVQ by adding disk type and array information because BVQ uses this information as base for creating the IO heat map.
    Below is a link to explanations how BVQ can be customized:
