Thanks for the details, which is really helpful. However I have tried this guide for section "Install vCloud Director Software on Additional Servers" but it didn't work out for me. Possibly I have already executed the same command without -r in Cell2. So any alternate work around at this stage?
1. copied the "responses.properties" file from Cell1 to Cell2 & the path is "/opt/vmware/vcloud-director/bin/"
2. in Cell2 --> # ls -ltrh /opt/vmware/vcloud-director/bin/responses.properties
-rw-------. 1 vcloud vcloud 430 Jul 9 12:26 responses.properties
# cd /opt/vmware/vcloud-director/bin/
2. in Cell2 I have tried to configure with -r option
[root@vcd5bin2 tmp]# ./vmware-vcloud-director-5.1.2-1068441.bin -r /opt/vmware/vcloud-director/etc/responses.properties
Before you upgrade to vCloud Director 5.1.2, read VMware KB article 2047922, which provides tools and procedures that enable you to detect and correct network adapter type mismatches before you upgrade. If you upgrade before correcting these mismatches, some of your virtual machines might have no network connectivity after the upgrade. Do you wish to proceed with the upgrade? (y/n)?y
