If you need to bypass some health checks in SDDC Manager when doing an VCF upgrade so it completes.

snapshot sddc manager

Modify the following
su
vi /opt/vmware/vcf/lcm/lcm-app/conf/application-prod.properties

modify the following entries from true to false
vsan.healthcheck.enabled=true
vsan.hcl.update.enabled=true
vsan.precheck.enabled=true
looks like this

vsan.healthcheck.enabled=false
vsan.hcl.update.enabled=false
vsan.precheck.enabled=false

comment out the below line and add the following line
lcm.nsx.backup.skip=false
looks like this

#lcm.nsx.backup.skip=false
lcm.nsxt.backup.skip=true

reboot sddc manager
