condor_update_machine_ad update - a machine ClassAd
condor_update_machine_ad [-help -version] condor_update_machine_ad[-pool centralmanagerhostname[:portnumber]] [-name startdname] path/to/update-ad
condor_update_machine_ad modifies the specified condor_startddaemon's machine ClassAd. The ClassAd in the file given by path/to/update-ad represents the changed attributes. The changes persists until the condor_startdrestarts. If no file is specified on the command line, condor_update_machine_ad reads the update ClassAd from stdin . Contents of the file or stdin must contain a complete ClassAd. Each line mustbe terminated by a newline character, including the last line of the file. Lines are of the form <attribute> = <value> Changes to certain ClassAd attributes will cause the condor_startdto regenerate values for other ClassAd attributes. An example of this is setting HasVM . This will cause OfflineUniverses , VMOfflineTime , and VMOfflineReason to change.
-help Display usage information and exit -version Display the HTCondor version and exit -pool centralmanagerhostname[:portnumber] Specify a pool by giving the central manager's host name and an optional port number -name startdname Send the command to a machine identified by startdname
This tool is intended for the use of system administrators when dealing with offline universes.
To re-enable matching with the VM universe jobs, place on stdin a complete ClassAd (including the ending newline character) to change the value of ClassAd attribute HasVM : echo "HasVM = True " | condor_update_machine_ad To prevent vm universe jobs from matching with the machine: echo "HasVM = False " | condor_update_machine_ad To prevent vm universe jobs from matching with the machine and specify a reason: echo "HasVM = False VMOfflineReason = \"Cosmic rays.\" " | condor_update_machine_ad Note that the quotes around the reason are required by ClassAds, and they must be escaped because of the shell. Using a file instead of stdin may be preferable in these situations, because neither quoting nor escape characters are needed.
condor_update_machine_adwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.
