Hitachi VSP Auto Dump Collection

We had posted previously on log collection from Hitachi unified storage and EMC VNX/Cellera storage arrays. In the same way, let us see how we can gather Auto Dump from Hitachi VSP storage arrays.

An Auto dump is a support log which is a mandate to analyse any kind of issue occurred on a Hitachi VSP Storage system. It is necessary to have Auto Dump collected during or shortly after an issue occurrence.

Normal Auto Dump can be collected by the customer and for detailed Auto dump you can take assistance from an HDS engineer.

For collecting an Auto Dump we need to have the SVP access, we can take an RDP session into the SVP. Basically, SVP is a Windows Vista system. Login to the SVP using the credentials.

Once you are logged in to the SVP you may either able to see the SVP console or the storage navigator Web console. If it is a storage navigator web console then go to “Maintenance” tab and select “Maintenance component General” It will open SVP console for you.

In the console, you can navigate to Auto Dump and you can click on the auto dump option to collect the log. You will be taken to a new window and you will be prompted to enter the target file location.

Once auto dump is started, it may take 30-45 minutes to complete.  Once it is completed you can navigate to C:\DKCxxx\TMP and you will find a file named hdcp.tgz last modified today (or the date you run the auto dump).

You can copy the file to your local PC or any server where internet connection is available.

Once we have files in our local system, we can upload the same to Hitachi Technical Upload Facility (TUF). This will require a valid Hitachi support case ID.

Hope this helped you. Feel free to provide your feedback in the comments section.

Way to gather simple trace from Hitachi Unified Storage

You may refer our previous post on VNX/Cellera log collection. Here we can see how to gather support logs from Hitachi Unified Storage (HUS 110, HUS 130 & HUS 150).

A “Simple Trace” is needed for analysis of all issues relating to the Hitachi storage systems. The trace can be obtained by the customer. It is critical to gather a trace as soon as possible after a problem is detected. This is to prevent log data wrapping and loss of critical information.

If a performance problem is being experienced, take one simple trace as soon as possible, while performance is affected. This can assist greatly in finding the root cause


Hitachi modular storage (HUS/AMS) log collection is a very simple task.

We can login to the WEB GUI using the controller IP Address (type the controller IP Address in a web browser and press enter). both HUS controllers have IP Address. Then in the left panel of the WEB GUI we can find “Simple Trace” Under Trace.

HUS Log Collection

Click on the simple trace and it will pop-up a screen, here will take some time to get it generated. We can monitor the percentage from the pop-up screen. Once the fetching completed we can download it to our local system. There may be multiple files we have to download for complete information from the same pop-up.

The file name will be as follows  smpl_trc1_systemserialnumber_yyyymmdd.dat 

Once we have files in our local system, we can upload the same to Hitachi Technical Upload Facility (TUF) Here we requires valid support case ID from Hitachi.
