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

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.

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).
  • Enterprise Database Plug-In Jobs
    • Veeam Plugin for Oracle RMAN
    • Veeam Plugin for SAP HANA
    • Veeam Plugin for SAP on Oracle
    • Veeam Plugin for DB2
    • Veeam Plugin for MS SQL
• The TlsIncompatibleHostIps registry value can be used to bypass the TLS requirement for all older Linux hosts, Quantum, Fujitsu, and Infinidat storage.
