Unable to reconfigure SRM or VR after upgrade to SRM/VRMS 8.3, 8,4 or 8.6 with more than 2 vCenters in Enhanced Link Mode.

Products

• VMware Live Recovery

Issue/Introduction

Symptoms:

 

• Unable to configure Site Recovery Manager / vSphere Replication with more than 2 vCenters in Enhanced Linked Mode.
• The VAMI summary page will take a long time to load.
• The error "Http failure response for https://xxx.xxx.xxx.xxx:5480/configure/requestHandlers/getSummaryInfo: 500 Internal Server Error"

Environment

VMware vSphere Replication 8.x
VMware Site Recovery Manager 8.x

Cause

Some VCs in Enhanced Linked Mode may be unreachable even with required ports open in firewall.

 

In the  drconfig log, you may see more than one vCenter server instance.  However, some of them are inaccessible from the VR appliance.

You will see errors similar to the following:

2023-07-14T16:44:53.929Z verbose drconfig[00914] [SRM@6876 sub=IO.Connection opID=61d5718f-b937-4708-96d7-4f027a193689-isReconfigureRequired] Attempting connection; <resolver p:0x00007f2958023040, 'VC fqdn:443', next:(null)>, last e: 110(Connection timed out).

 

The error "Http failure response for https://xxx.xxx.xxx.xxx:5480/configure/requestHandlers/getSummaryInfo: 500 Internal Server Error" is due to insufficient responseTimeout and connectTimeout.

Resolution

Workaround:

• Increase the  socketTimeout,responseTimeout and connectTimeout  entries in /opt/vmware/drconfigui/webapps/configure/WEB-INF/classes/config-service.properties  file to following values:

responseTimeout=400000
connectTimeout=400000
socketTimeout=400000

• Restart the drconfigui service after changing the values: systemctl restart drconfigui.

 

Fix: Upgrade to vSphere Replication version 8.7.
