Cause

This occurs if the version of the Managed Host (package VRTSsfmh) is earlier than the CS, and this issue ONLY applies to a newly-installed 7.2 CS, not one that has been upgraded from a previous version and has 7.0 MHs already added.

The issue can be verified by the VRTSsfmh log from the MH, as shown below.

Resolution

Upgrade the MH (package VRTSsfmh) to 7.2 and re-add the host to the CS.

If this is not possible, as a workaround, set up a manual trust:
  • On a Linux managed host, enter the following commands:

    export EAT_HOME_DIR=/opt/VRTSsfmh

    export EAT_DATA_DIR=/var/opt/VRTSsfmh/sec

    /opt/VRTSsfmh/bin/vssatbin setuptrust -b CS_FQDN:14545 -s high

  • On a Windows managed host, enter the following commands:

    set EAT_HOME_DIR=C:\Program Files\Veritas\VRTSsfmh

    set EAT_DATA_DIR=C:\ProgramData\veritas\VRTSsfmh\sec

    vssatbin setuptrust -b CS_FQDN:14545 -s high

Issue/Introduction

After adding the Managed Host (MH) successfully on a Veritas InfoScale Operations Manager (VIOM) 7.2 Central Server (CS), the MH is not refreshed and the error message "V-383-50513-5778 Communication failure with managed host" appears.
