Opened: Aug 26, 2021
Severity: 3-Major

Symptoms

Loading a UCS file from another BIG-IP results in an error message similar to: "/usr/bin/tmsh -n -g -a load sys config partitions all platform-migrate" - failed. -- 010713d0:3: Symmetric Unit Key decrypt failure - decrypt failure The error message is misleading as the issue is unrelated to master key decryption.

Impact

Platform migration fails with a misleading error message.

Conditions

-- Loading a UCS archive from a different BIG-IP. -- The UCS archive does not contain a ".unitkey" file. -- The target system does have the correct master key value configured. -- There is some other MCPD validation issue in the configuration.

Workaround

Once the issue has happened, you can either: - Examine the LTM log file for other error messages from MCPD and then correct the configuration issue(s). OR: - Re-start MCPD.

Fix Information
