Symptoms:

VCF 4.5 Bring up Network validation fails with "Gateway IP Address for Management is not contactable"

VMware Cloud Foundation 5.0
Vmware Cloud Foundation 4.5

The validation workflow is trying to open certain ports like 7,22,80,8443 to check gateway, instead of executing ping to validate the Gateway causing Gateway validation to fail

This is a known issue, We are working on fixing this in next versions.

Workaround:

There're two workarounds to fix this, follow one :


Workaround #1 :

If this is the only failing validation, then it's possible to start bringup using API:

•   generate json from XLS using command:

/opt/vmware/sddc-support/sos --jsongenerator --jsongenerator-input <path-to-xls> --jsongenerator-design vcf-ems

•   run bringup using the generated json:

curl -k -u admin:'<password>' -X POST https://localhost/v1/sddcs -H "Content-Type: application/json" -d "@/opt/vmware/sddc-support/cloud_admin_tools/Resources/vcf-ems/vcf-ems.json"

Workaround #2 :

Apply the attached patch that will just skip the validation of the management gateway and result in a successful validation. Steps for applying the patch:
 

• Find and backup the same file under /opt/vmware/bringup/webapps/bringup-app/lib
• Copy the patch file to the above folder

                chown vcf_bringup:vcf <patch-file>

• Restart vcf-bringup service

                systemctl restart vcf-bringup

•  Wait for the bringup service to restart and retry the validation from Cloudbuilder UI

Impact/Risks:
VCF 4.5 Bring up validation would fail
