Updating Storage Backend Authentication Information

To prevent the storage backend from becoming temporarily unavailable when the existing secret is modified directly, you are advised to update the authentication information by creating a new secret, replacing the reference to the existing secret, and then deleting the old secret.

Procedure

Prepare a new secret configuration file, for example, backend-secret-new.yaml.

apiVersion: v1
kind: Secret
metadata:
  name: backend-demo-new
  namespace: huawei-csi
type: Opaque
stringData:
  user: "admin"
  password: "******"
  authenticationMode: "0"

Create a secret.

kubectl apply -f backend-secret-new.yaml

Update StorageBackendClaim and update secretMeta to reference the new secret. CSI automatically synchronizes the new secret to StorageBackendContent and uses the new authentication information to log in to the storage device again.
```
kubectl patch sbc backend-demo -n huawei-csi --type merge -p '{"spec":{"secretMeta":"huawei-csi/backend-demo-new"}}'
```

Check the storage backend creation result.

kubectl get StorageBackendContent

The following is an example of the command output. If the online status of StorageBackendContent is true, the update is successful.

NAME              CLAIM                       SN               VENDORNAME   PROVIDERVERSION   ONLINE   AGE
content-xxxxxxx   huawei-csi/backend-demo     xxxxxxxxxxxxxx   Huawei       4.12.0            true     53d

Delete the old secret.

kubectl delete secret backend-demo -n huawei-csi
