Allocating static PV for Media pods

When you want to use a disk with specific performance parameters, you can statically create the PV and PVC. You must allocate static PV and PVC before deploying the NetBackup server for the first time.

To allocate static PV for Media pods

Create storage class in cluster as per recommendations.
See How does the Config-Checker utility work. for storage class recommendation.
This newly created storage class name is used while creating PV and PVC's and should be mentioned for Catalog, Log, Data volume in the environment CR in mediaServer section at the time of deployment.
For more information on creating storage class, see Create a custom storage class.
For example,
```
kind: StorageClass
apiVersion: storage.k8s.io/v1
metadata:
  name: managed-premium-retain
provisioner: disk.csi.azure.com
reclaimPolicy: Retain
allowVolumeExpansion: true
volumeBindingMode: Immediate
parameters:
  storageaccounttype: Premium_LRS
  kind: Managed
```

Calculate number of disks required.

The following persistent volumes are required by Media pods:

Data and Log volume disk per replica of media server.

Use the following format to form PVC names.

For media server

data-<resourceNamePrefix_of_media>-media-<media server replica number. Count starts from 0>
logs-<resourceNamePrefix_of_media>-media-<media server replica number. Count starts from 0>

Example 1

If user wants to deploy a media server with replica count 3.

Names of the Media PVC assuming resourceNamePrefix_of_media is testmedia.

For this scenario, you must create total 8 disks, 8 PV and 8 PVCs.

6 disks, 6 PV and 6 PVCs for media server.

Following will be the names for media server volumes

For data:

data-testmedia-media-0
data-testmedia-media-1
data-testmedia-media-10
data-testmedia-media-2

For log:

logs-testmedia-media-0
logs-testmedia-media-1
logs-testmedia-media-2

Example 2

If user wants to deploy a media server with replica count 5

Names of the Media PVC assuming resourceNamePrefix_of_media is testmedia.

For this scenario, you must create 12 disks, 12 PV and 12 PVCs

10 disks, 10 PV and 10 PVCs for media server.

Following will be the names for media server volumes

For data:

data-testmedia-media-0
data-testmedia-media-1
data-testmedia-media-2
data-testmedia-media-3
data-testmedia-media-4

For log:

logs-testmedia-media-0
logs-testmedia-media-1
logs-testmedia-media-2
logs-testmedia-media-3
logs-testmedia-media-4

Create required number of Azure disks and save the ID of newly created disk.
For more information, see Azure Disk - Static

Create PVs for each disk and link the PVCs to respective PVs.

To create the PVs, specify the created storage class and diskURI (ID of the disk received in step 3). The PV must be created using the claimRef field and provide PVC name for its corresponding namespace.

For example, if you are creating PV for catalog volume, storage required is 128GB, diskName is primary_catalog_pv and namespace is test. PVC named catalog-testprimary-primary-0 is linked to this PV when PVC is created in the namespace test.

                          namespace: test

Create PVC with correct PVC name (step 2), storage class and storage.

For example,

apiVersion: v1
               kind: PersistentVolumeClaim
               metadata:
                 name: catalog-testprimary-primary-0
                 namespace: test
               spec:
                 storageClassName: "managed-premium-retain"
                 accessModes:
                        - ReadWriteOnce
                 resources:
                        requests:
                          storage: 128Gi

Deploy the Operator.
Use previously created storage class names for the volumes in mediaServers section in environment CR spec and deploy environment CR.
