Workaround for both POWERPROTECT DATA MANAGER-274062 and POWERPROTECT DATA MANAGER-252524

  1. Power off and on the VM Protection Engine (vProxy) using vSphere and wait 5-10 minutes before proceeding to step 2.

To verify if POWERPROTECT DATA MANAGER-252524 is the issue affecting your environment.

  2. Run on vProxy to check for defunct process.

    # ps -ef | grep vmdkfs

    Step2 command results

    Note: To view the admin/root password for the VM Direct Engines, use the commands below run as root on the PowerProtect Data Manager. This lists all passwords for all VM Direct Engines, both VM, and NAS.
    source /opt/emc/vmdirect/unit/vmdirect.env  &&  /opt/emc/vmdirect/bin/vproxymgmt get -secret

     

  3. Tcp connections can also be observed left in a "CLOSE_WAIT" status between the VM Direct Engine and the ESXi host. Run below on the VM Direct Engine over ssh

    # netstat -anp | grep -E ":902"

    Step3 command results

    Or
    # ss -at <-- for new versions of Suse Linux where netstat is no longer in use.
