Error: "Could not connect to host" is reported when attempting to add VCS to VRP 10.0

Problem

For VRP 10.0, when attempting to add a new Veritas Cluster Server (VCS) to Veritas Resiliency Platform (VRP), the operation fails while trying to connect to the cluster nodes.

The issue can occur for VCS of any OS platform (WIndows, Linux, AIX)

Error Message

From the VRP Console, while attempting to add the cluster, it will report below error

Could not contact host

One of the following may have happened.

-VRTSSfmh package is not installed on the host

-Veritas Infoscale Operations Manager Messaging Service (xprtld) on host is down

-Host is not reachable from Infrastructure Management Server

When running a getvitals command "/opt/VRTSsfmh/bin/xprtlc -l https://<VCS_node_Name/IP>:5634/world/getvitals" from the IMS to the Veritas Cluster node or vice-versa would give below error

Error: Failed to establish secure connection (err=168)

Cause

The issue occurs if the VRTSsfmh package on the VCS nodes is of a lower version than the one supported by VRP 10.0 Infrastructure Management Server (IMS).

VRP 10.0 only supports VRTSsfmh package of version 7.2 and above. If any lower version VRTSsfmh package is detected (For example: VRTSsfmh 7.0.0.0), the secure communication fails thereby preventing the IMS to communicate with the cluster nodes and vice-versa.

Solution

To begin troubleshooting this issue, ensure to verify the VRTSsfmh package on the Cluster nodes

For Windows

=================================

Browse to Add/Remove Programs and verity the version of Veritas Infoscale Managed Host package

For UNIX

================================

Run the command rpm -q VRTSsfmh

For AIX

===============================

Run the command lslpp -L | egrep -i VRTSsfmh 

If the VRTSsfmh version is lower than 7.2 ,then perform below steps

1) Download the 7.2 VRTSsfmh package from Veritas Infoscale Operations Manager 7.2. The package name would be "Veritas_InfoScale_Operations_Manager_Managed_Host_Bundle_7.2.0.zip"

2) Extract it locally.

3) It will contain the VRTSsfmh packages specific to different OS platform. Download the one that aligns to the OS platform of the intended VCS nodes.

4) Upgrade the existing VRTsfmh package to 7.2. Refer Page 66 onward of Upgrading Managed Host using Operating system commands

NOTE #1: It is preferred to perform an upgrade rather than an uninstall-old->install-new. Also, the entire operation of upgrading the package does not require any maintenance window and does not have any impact on the running cluster.

NOTE #2: Veritas Clusters can work with higher versions of VRTSsfmh package installed on them.
