LSB_UTMP=y | Y
If set, enables registration of user and account information for interactive batch jobs submitted with bsub -Ip or bsub -Is. To disable utmp file registration, set LSB_UTMP to any value other than y or Y; for example, LSB_UTMP=N.
LSF registers interactive batch jobs the job by adding a entries to the utmp file on the execution host when the job starts. After the job finishes, LSF removes the entries for the job from the utmp file.

utmp file registration is not supported in a MultiCluster environment.
Because interactive batch jobs submitted with bsub -I are not associated with a pseudo-terminal, utmp file registration is not supported for these jobs.
