Quantum DXi Storage With Firmware 3.x Does Not Work with Veeam Backup & Replication 12

Last update date:


Affected products:

Veeam Backup & Replication

Affected releases:


Fixed releases:

No fixed releases provided.



When attempting to add Quantum DXi storage with firmware 3.x to Veeam Backup & Replication, the following error is shown: Failed to StartAgent: Failed to construct ClientAgentProtocol.   If the Quantum DXi storage was added to Veeam Backup & Replication prior to upgrading to Veeam Backup & Replication 12 or newer, after the upgrade, the storage will be listed as unavailable.


Veeam Backup & Replication cannot connect to the Quantum DXi storage because a secured TLS communication channel cannot be created. Starting in Veeam Backup & Replication 12, communication with deduplicating storage appliances is secured using a TLS connection. In order to create such a TLS connection, urandom, random, and srandom are required, and Quantum DXi firmware version 3.x does not include these utilities.


Upgrade Quantum DXi device to firmware version 4.x or newer (if available for model).

More Information

Workaround The following registry value can be created on the Veeam Backup Server to force Veeam Backup & Replication to connect to the storage device without using a secure TLS connection.  Key Location: HKLM\SOFTWARE\Veeam\Veeam Backup and Replication\ Value Name: TlsIncompatibleHostIps Value Type: String Value (REG_SZ) Value Data: <IPs of Quantum devices, separated by commas>   Note: The TlsIncompatibleHostIps registry value does not function as a workaround for transaction log backup jobs (i.e., MSSQL, Oracle,  or PostgreSQL). The TlsIncompatibleHostIps registry value can be used to bypass the TLS requirement for all older Linux hosts, Quantum, Fujitsu, and Infinidat storage.
