Troubleshooting NetBackup servers with short names

  1. If NetBackup Kubernetes operator is not able to resolve backup server or media server based on short names, perform the following steps:

    • While fetching certificates if you get a message, EXIT STATUS 8500: Connection with the web service was not established. Then confirm from the nbcert logs whether hostname resolution successful or not. If it has failed, then perform the following steps:

    • Update the Kubernetes operator deployment.yaml and add the hostAliases in the deployment.

    • In the following hostAliases example,

      • backupserver.sample.domain.com and mediaserver.sample.domain.com are the hostnames of NetBackup primary and media server.

      • IP: 10.20.12.13 and IP: 10.21.12.13 are the IP addresses of NetBackup primary and media server. 

      hostAliases:
- hostnames:
  - backupserver.sample.domain.com
  ip: 10.20.12.13
- hostnames:
  -  mediaserver.sample.domain.com
  ip: 10.21.12.13

      Copy, paste the hostAliases example details in the text editor and add to the hostAliases in the deployment.

  2. If datamover is not able to resolve short names of backup server or media server. To resolve this issue, perform the following steps:

    • Create a ConfigMap with backup server name.

    • Add datamover.hostaliases field, map with IP addresses to the hostname.

    • In the following configmap.yaml example,

      • backupserver.sample.domain.com and mediaserver.sample.domain.com are the hostnames of NetBackup primary and media server.

      • IP: 10.20.12.13 and IP: 10.21.12.13 are the IP addresses of NetBackup primary and media server. 

      apiVersion: v1

data:
  datamover.hostaliases: |
        10.20.12.13=backupserver.sample.domain.com
        10.21.12.13=mediaserver.sample.domain.com
  datamover.properties: |
        image=reg.domain.com/datamover/image:latest
  version: "1"
kind: ConfigMap
metadata:
  name: backupserver.sample.domain.com
  namespace: kops-ns

      • Copy the configmap.yaml file details.

      • Open the text editor and past the yaml file details.

      • Then, save it with the yaml file extension to the home directory from where the Kubernetes clusters are accessible.

    • To create the configmap.yaml file, run the command:kubectl create -f ConfigMap.yaml.
