To create a cloud immutable storage unit:

1. Use msdpcldutil command to create the cloud immutable volume. Note down the volume name, it will be used in step 4.
2. On the NetBackup Web UI, navigate to Storage > Disk pools, and click Add.
3. In Disk pool options, click Change to select a storage server.

   Enter the Disk pool name.

   If Limit I/O streams is left cleared, the default value is Unlimited and may cause performance issues.

   After all required information is added, click Next.

4. From the Volume drop-down list select a volume or add a new volume. Provide the name that is created in step 1 by msdpcldutil.

   On the Cloud storage provider window, select Hitachi Content Platform for Cloud Scale - LAN, Hitachi Content Platform for Cloud Scale - WAN, Seagate Lyve Cloud, or Veritas Access Cloud from the list.

   Under Region, select the appropriate region.

   Enter the credentials to complete the setup. You can configure additional options here such as adding a proxy server.

   Under WORM, check Use object lock.

   Under Cloud bucket, select Select or create cloud bucket and click Retrieve list. Select a bucket from the list. You can also provide the bucket name. If you provide the bucket name, ensure this bucket is created by msdpcldutil so that it is Object Lock enabled.

   If encryption is needed, select the data encryption option for data compression and encryption. MSDP can use KMS encryption which encrypts the data using a managed key. Using KMS requires that a KMS server has previously been configured.

   Enter all required information based on the selection and click Next.

5. In Replication, click Next.
6. On the Review page, verify that all settings and information are correct. Click Finish.

   The disk pool creation and replication configuration continue in the background if you close the window. If there is an issue with validating the credentials and configuration of the replication, you can use the Change option to adjust any settings.

7. In the Storage unit tab, click Add.
8. Select Media Server Deduplication Pool (MSDP) and click Start.
9. In Basic properties, enter the Name of the MSDP storage unit and click Next.
10. Select the disk pool that was created and select the Enable WORM/Lock until expiration box, and click Next.
11. In Media server, use the default selection of Allow NetBackup to automatically select, and click Next.
12. Review the setup of the storage unit and then click Save.
