Solution 2: Specify a new BIG-IQ master key passphrase

Perform this task when a BIG-IQ system and a data collection device (DCD) fail to discover one another, and you do not 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.
When you don't know the BIG-IQ system's master key passphrase, you can perform the following task to restore both the BIG-IQ and DCD system configurations to their factory defaults and begin a new first-time setup procedure on each system. Once these setup procedures are 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 BIG-IQ 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. Log in to the BIG-IQ system user interface and follow the first-time setup procedure.
    During the master key step of the procedure, choose a new master-key passphrase, and store the passphrase in a safe place.
  6. Using a program such as PuTTY, open a console window on the DCD system.
  7. Log in to the system.
  8. At the system prompt, reset the DCD system configuration to the default by typing this command:
    clear-rest-storage -d -l
  9. 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.
  10. From the user interface of the BIG-IQ system, rediscover the DCD system.
