8. Restore settings

Before you start

Every host refreshed, renewed and Connected (stage 7). The original values you recorded in 5.1.

Put back exactly what you recorded in 5.1.

8.1 minutesBefore back to 1440​

govc:

govc option.set vpxd.certmgmt.certs.minutesBefore 1440

vSphere UI: vcenter.example.org > Configure > Settings > Advanced Settings > Edit Settings > vpxd.certmgmt.certs.minutesBefore = 1440 > Save.

8.2 DRS back to fullyAutomated, with the original threshold​

govc:

govc cluster.change -drs-enabled=true -drs-mode fullyAutomated -drs-vmotion-rate 3 /DC-01/host/Cluster-01

Use your own recorded vmotionRate for -drs-vmotion-rate.

vSphere UI: Cluster-01 > Configure > Services > vSphere DRS > Edit > Automation Level: Fully Automated, Migration Threshold back to the recorded position > OK.

8.3 HA back on, with the original admission control​

govc:

govc cluster.change -ha-enabled=true -ha-admission-control-enabled=true /DC-01/host/Cluster-01

vSphere UI: Cluster-01 > Configure > Services > vSphere Availability > Edit > turn vSphere HA on. Check Failures and responses > Host Monitoring is on, and Admission Control matches the recorded policy (for example Cluster resource percentage, Host failures cluster tolerates: 1, Override calculated failover capacity unticked, which gives the auto-computed 25 % CPU and 25 % memory on a four-host cluster) > OK.

HA reconfigures each host and elects a new primary. Wait until every host shows the HA state Running (Primary) or Connected (Secondary) in Cluster-01 > Monitor > vSphere HA > Summary.

Verify before continuing​

govc option.ls vpxd.certmgmt.certs.minutesBefore
govc object.collect -json /DC-01/host/Cluster-01 configurationEx | jq '.[0].val | {
  drs: .drsConfig,
  das: (.dasConfig | {enabled, hostMonitoring, vmMonitoring, admissionControlEnabled, admissionControlPolicy})
}'
  • minutesBefore is 1440.
  • The JSON matches the JSON you saved in 5.1, field for field.
  • HA shows a primary and no configuration errors on any host.
