Replacing protection storage

After you replace a DD protection storage system, you can use the PowerProtect Data Manager UI to update the required storage settings in PowerProtect Data Manager for the replacement storage. Only the Administrator role can update the protection storage settings in PowerProtect Data Manager. This process only applies to stand-alone DD systems, which are DD systems not managed by DDMC.

The replacement of a DD protection storage system that is used with PowerProtect Data Manager can involve either of the following use cases:

  • You perform a DD controller upgrade or head swap that replaces the protection storage system without requiring the migration of data.
  • You perform collection replication or DD Cloud migration to migrate data from the original DD system to a new replacement system with the same or higher capacity.
CAUTION:The replacement DD system must have all the storage units, DD Boost users, and data that existed on the original DD system.

After you replace the DD system, ensure that you meet the following requirements before using the PowerProtect Data Manager UI to update the storage settings:

  • All the protection policies that use the DD storage system are disabled.
  • All the running protection jobs are completed.
  • All the required data has been manually migrated as needed from the original DD system to the replacement DD system.

Use one of the following procedures to update the protection storage settings in PowerProtect Data Manager after replacing the DD storage system.

Updating the storage settings when data IP addresses are unchanged

Use the following procedure if you replaced the DD storage system and none of the network settings or data IP addresses have changed.

  1. From the left navigation pane, select Infrastructure > Storage.

    The Storage window appears.

  2. On the Protection Storage tab, select the DD and then click Discover.

PowerProtect Data Manager automatically discovers the replacement DD system and updates the storage settings for the replacement system. After discovery, the replacement DD attributes appear on the Protection Storage tab of the Infrastructure > Storage window.

Updating the storage settings when data IP addresses are changed

Use the following procedure if you replaced the DD storage system and any of the network settings or data IP addresses have changed.

NOTE:When data IP addresses have changed, update the network interface information for the replacement DD system.

  1. From the left navigation pane, select Infrastructure > Storage.

    The Storage window appears.

  2. On the Protection Storage tab, select the DD and then select More Actions > Replace System.
  3. Review the warning message about policies and running jobs, and then click Continue.

  4. In the Replace System dialog box, specify the replacement DD system settings and then click Apply:

    • In the Address field, specify the DD system management address as the fully qualified domain name (FQDN) or IP address.
    • In the Port field, specify the port for SSL communication. The default port is 3009.

    • Under Host Credentials, select a new set of credentials or click Add.

      If a trusted certificate does not exist for the storage system, a dialog box appears requesting certificate approval. Click Verify to review the certificate, and then click Accept.

    • Under Network Mapping, specify the replacement data IP address for each listed data IP address that has changed.

A system job is created for updating the storage settings for the replacement DD system. You can monitor the system job in the System Jobs window.

NOTE: You must wait until the replacement system job completes before you perform any PowerProtect Data Manager operations that use the DD system being replaced.

After the system job completes, the replacement DD attributes appear on the Protection Storage tab of the Infrastructure > Storage window. The protection policies that use the DD system are automatically updated with the replacement DD settings.
