  • VSA Proxy Downgrading/Locking VDDK Version
    Posted: 01-28-2019, 10:34 AM

    Hi,

    is there any way to downgrade or lock the VDDK version a VSA Proxy is using?

    We have 2 vcenters, one is using 6.7 and one is still using 5.1 (pretty old, but i can't change it atm).

    We created a seperate VSA Proxy for the 5.1 vcenter to backup.

    Everything was running fine, till somebody temproraly attached the vsa-proxy to the new vcenter.

    He changed it back, but the damage was done, the VSA Proxy is now also loading the newest VDDK and therefore can't backup the old 5.1 stuff anymore. We fixed the issue with a hole new vsa for the moment.

    Is there anything we can use, to prevent this in the future?

    Setting a Registry key or is it possible to quickly downgrade the vddk of an vsa proxy?

    Would a "Repair Software" had also worked?

    kind regards and thank you in advanced

    Joerg

    Hello Joreg,

     

    This is possible, but the answer may depend on what Commvault service pack you are using.

    For SP13, you can set the following additional setting on your VSA proxy.

     

    Name: nVDDKVersionPath

    Category: VirtualServer

    Type: integer

    Data: 602

     

    For information on using additional settings, please see: http://documentation.commvault.com/commvault/v11_sp13/article?p=8677.htm

     

    6.0.2 is the latest supported version of VDDK that will back up an ESX 5.1 host.

     

    Kind regards

    Allister
