Resolution

To resolve this issue, increase the personality export timeout settings in SDDC Manager by following the below steps:

2. Navigate to the directory /opt/vmware/vcf/lcm/lcm-app/conf/ and take backup of application-prod.properties file

cp application-prod.properties /var/tmp/application-prod.properties.bak

3. Add following parameters (if they don't already exists) to increase the personality export timeout:

personality.export.connection.timeout=1800000
personality.export.read.timeout=1800000

4. Restart the LCM service to apply the changes:

systemctl restart lcm
