Solution 1: Specify the BIG-IQ passphrase on the DCD

Use this procedure when a BIG-IQ system and a data collection device (DCD) fail to discover one another, but you know the passphrase for the BIG-IP system's master key. A discovery operation fails if the master keys of the BIG-IQ system and the DCD system don't match.
To resolve the discovery failure, you can restore the DCD system configuration to the factory default and begin a new first-time setup procedure. During DCD setup, you specify the same master key passphrase that's on the BIG-IQ system. Once the procedure is completed, you can attempt the discovery operation again.
  1. Using a program such as PuTTY, open a console window on the BIG-IQ system.
  2. Log in to the system.
  3. At the system prompt, reset the DCD system configuration to the default by typing this command:
    clear-rest-storage -d -l
  4. If you see the message
    Member of an HA pair. Use
    ha_reset
    before trying to clear storage
    , type this command:
    ha_reset
    local discovery address
    You can ignore the message
    Error: error doing query...
  5. Repeat step 3.
  6. Obtain the BIG-IQ system master key passphrase for the next step.
  7. Log in to the DCD system user interface and follow the first-time setup procedure.
    During the master key step of the first-time setup procedure, ensure that you type the BIG-IQ system master key passphrase.
  8. Log in to the BIG-IQ system user interface and rediscover the DCD system.
