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.
