    Hello,

    We updated Commvault to v11.20.17 last week. After the update we couldn't backup some virtual machines with san transport mode. Our previous version is v11.19.18.

    I deleted server names etc. from logs.
     
    I created new subclient with failed virtual machines. I can't backup with auto or san transport mode but I can with nbd.
     
    Anyone can help me with this situation?

    Hi İbrahim,

     

    Can you open a ticket with support?

    I beleive this is an issue with VDDK version 7 on the proxies and they can help you downgrade to 673.

    are you on Vcenter Version 7 ?

    Hi Gary,

    Thank you for your reply.

    I didn't want to open a call because maybe it's a simple problem.

    Our vCenter is 6.7

    Hello,

    I'm sharing Commvault Engineer's reply;

    "SP20 is using VDDK 7.0 and we have several other cases in development escalation for the same issue. From what I can see, there's an issue with VMware's VDDK 7.0 with SAN transport and our developers are working with VMware on it."

    I think they will publish hotfix for this issue.
