Troubleshooting command device update issues

1. Delete the PVC. Enter:

   kubectl delete pvc pvc-sdb -n ucp

   If the status is in the Terminating state and you are unable to proceed, in a separate SSH session, enter:
   

   

   
   

   kubectl patch pvc pvc-sdb -n ucp -p '{"metadata":{"finalizers":[]}}' --type=merge

2. Delete the PV. Enter:

   kubectl delete pv pv-sdb

   If you are unable to proceed, enter:

   kubectl patch pv pv-sdb -n ucp -p '{"metadata":{"finalizers":[]}}' --type=merge

1. Tear down the running sdi-gateway-block PODs. Enter:

   kubectl patch deployment sdi-gateway-block -n ucp --type "merge" -p '{"spec":{"replicas":0}

2. Retrieve the current running image. Enter:

   kubectl get deployment sdi-gateway-block -n ucp -o yaml | grep "image:"

   Note the output image name for use in the following step. For example: triangulum-docker-dev-sc.repo.sc.eng.hitachivantara.com/sdi-gateway-block:v9.1.0.dev-4662
3. Replace the docker image with the image name output above to remove the command device.

   For example, enter:

   kubectl patch deployment sdi-gateway-block -n ucp --type "merge" -p '{"spec":{"template":{"spec":{"containers":[ {"name":"sdi-gateway-block", "image":"triangulum-docker-dev-sc.repo.sc.eng.hitachivantara.com/sdi-gateway-block:v9.1.0.dev-4662", "volumes":[{"name":"log-dir", "hostPath":{"path":"/var/log/sdi-gateway", "type":"DirectoryOrCreate"}}]} ]}}

kubectl patch deployment sdi-gateway-block -n ucp --type "merge" -p '{"spec":{"replicas":1}}'
