Installation, Licensing, and Initial Configuration

A BIG-IP Administrator receives an RMA replacement for a failed F5 device. The BIG-IP Administrator tries to restore a UCS taken from the previous device, but the restore fails.

The following error appears in /var/log/ltm:

mcpd[2395]: 01070608:0: License is not operational (expired or digital signature does not match contents)

What should the BIG-IP Administrator do to avoid this error?

  • A Remove the license information from the UCS archive
  • B Use the appropriate tmsh command with the no-license option
  • C Revoke the license prior to restoring
  • D Reactivate the license on the new device using the manual activation method
Explanation

A UCS archive from the original device includes that device's license, which is bound to device-specific information and will not be valid on the replacement RMA hardware, causing the "License is not operational" error during restore. F5 documents the no-license option for the tmsh load sys ucs command specifically for this purpose: it performs a full restore of the UCS archive's contents while excluding the license file, so the license already activated on the new RMA device is preserved instead of being overwritten by the incompatible license from the old device. This avoids the digital-signature/license mismatch error during the restore.
