| Description | TLD(0) unavailable: initialization failed: Control daemon connect or protocol error. |
| Event Information | This information from some newsgroups may help you: ------------------------------------------------------------------------------ The cause of this problem is most often a result of communication problems. There are two NetBackup daemons for robotic control, one runs on the machine with robotic control, the other runs on the machine that has drives in the robot. For example, if the robot is a TLD robot the two daemons are tldcd ( runs on the server with robotic control) and tldd (runs on server with drives on the robot). In this commonly occurring problem, the drives will change from TLD control to AVR control. This is so the jobs will go into a pending mount state, rather than failing. That happens so that if network communications were to fail between two server for a short time, then there would be no need to fail the jobs and they could wait until the connection comes back up. However, at times this can be caused by more severe problems. The above error is what will cause drives in a robot to go into an AVR control mode. It is not possible to give a single cause or a single solution. This is because these two daemons are unable to communicate. Some common causes are: 1. Network connectivity has just plain failed. In this case, the network must be restored. 2. There are multiple interfaces on one or both of the machines that cannot route to or resolve each other. In this case, either routing needs to be changed so that a request going will be able to reach its destination. Also, adding the proper host names to the /etc/hosts file has been shown to work in some situations. 3. The tldcd daemon has enters an uninterruptible state or is hung, thus making it unable for it to reply to tldd. In this case, shutdown the media management daemons by running /usr/openv/volmgr/bin/stopltid. 4. The /etc/services file is missing the correct entries on one or both the servers. ------------------------------------------------------------------ |
