connections
Query LSF data management connections. Lists currently connected mbatchd daemons, with LSF data manager management host names, their status, and the outgoing and incoming connections for remote LSF data managers.
bdata connections [-w]
Output
The bdata connections output has the following sections.
The LOCAL section displays two tables:
- The first table displays the configuration of the LSF_DATA_HOSTS and LSF_DATA_PORT parameters for the local LSF data manager. The currently active LSF data manager management host name is marked with an asterisk ([*]).
- The second table displays the connection status of registered mbatchd daemons.
- CLUSTER
- Displays the cluster name.
- MASTER
- Displays the name of the LSF cluster management host that is connected to this data manager.
- STATUS
- Displays the connection status for the cluster (ok or disc).
The OUTGOING REMOTE section displays the connection
status of remote LSF data
managers for stage out jobs that are configured in the RemoteDataManagers
section of the lsf.datamanager file:
- CLUSTER
- Corresponds to the CLUSTER column in the lsf.datamanager file, and displays the name of the remote LSF cluster.
- LSF_DATA_HOSTS
- Displays the data hosts configured in the RemoteDataManagers section of the lsf.datamanager file. The currently active LSF data manager management host name is marked with an asterisk ([*]).
- LSF_DATA_PORT
- Displays the LSF data manager connection port that is specified by the LSF_DATA_PORT parameter in the lsf.conf file.
- STATUS
- Displays the connection status (ok or disc).
The INCOMING REMOTE section displays the status of remote LSF data
managers that connect to the local LSF data
manager to query for file availability.
- CLUSTER
- Corresponds to the CLUSTER column in the lsf.datamanager file, and displays the name of the remote LSF cluster.
- DMD_MASTER
- Displays the connected LSF data manager management host name for the cluster.
- LSF_DATA_PORT
- Displays the LSF data manager connection port that is specified by the LSF_DATA_PORT parameter in the lsf.conf file.
- STATUS
- Displays the connection status (ok or disc).
If the RemoteDataManagers section is configured in the lsf.datamanager file in the local cluster, the OUTGOING REMOTE section is displayed. If the RemoteDataManagers section is configured in the lsf.datamanager file in the remote cluster, the local cluster displays the INCOMING REMOTE section. Only the cluster that is sending jobs needs to configure the RemoteDataManagers section.
