Síntomas

Backups may fail with the following errors:

DDR result code: 5049, desc: file not found
DDR result code: 5341, desc: SSL library error "failed to import host or ca certificate automatically"
DDR result code: 5008, desc: invalid argument

When following Dell article 197106, Avamar and Data Domain Integration: DD Showing Red in Avamar AUI and or user interface Resolution Path, the certificates are not generated.

Upon checking the MCS logs, there is an exception related to the SCP protocol.

Causa

Review the mcserver log:

/usr/local/avamar/var/mc/server_log/mcserver.log.0

Caused by: java.io.IOException: SCP unexpected cmd: Scp is disabled. Access denied.

This shows that the SCP protocol is disabled on Data Domain.

The flow of syncing certificates between Avamar and Data Domain requires SCP to be enabled as demonstrated below:

Avamar runs a command on Data Domain using the Data Domain public key for password-less authentication. The first command is to generate a Certificate Signing Request (CSR) on Data Domain.
The Avamar then attempts to copy the CSR from Data Domain using SCP, but fails to do so when SCP is disabled on Data Domain.
Avamar would use the CSR to sign a certificate issued to Data Domain by the Avamar root certificate authority. On Data Domain it is called the 'imported-host ddboost" certificate.

Checking the Data Domain user interface shows that SCP is disabled:

Figure 1: Data Domain user interface shows that SCP is disabled

Resolución

Enable SCP in the Data Domain web interface

From Administration > Access > Services > Check SCP > Configure > Check Allow SCP.
