Raising the Replica Feature Level


There are two important rules related to raising a replica's feature level:

To raise the replica feature level:

  1. After installing the new version of ClearCase on a server host, determine which replica masters the VOB object:
  2. cleartool describe vob:vob-tag 

    If the replica whose feature level you want to raise first does not master the VOB object, you must transfer mastership of the VOB object:

    1. Change mastership of the VOB object:
    2. multitool chmaster replica-name vob:vob-tag

    3. Export an update packet to the replica whose feature level you want to raise:
    4. multitool syncreplica –export –fship replica-name@vob-tag

    5. At the receiving replica, import the packet:
    6. multitool syncreplica –import –receive

  3. Determine whether the replica is self-mastering:
  4. cleartool describe replica:replica-name@vob-tag 
  5. If the replica is not self-mastering, convert it to a self-mastering replica. See Transferring Mastership of a Replica Object.
  6. Raise the feature level of the replica. Enter this command on the replica host:
  7. cleartool chflevel –replica feature-level replica:replica-name@vob-tag 
  8. Export update packets to all other replicas in the VOB family to inform them about the feature level change.
  9. (optional) Change mastership of the replica back to the original master replica.
