Note
This table assumes that all events process normally. The status of a status file is managed only while the status service is operating. Therefore, if the stsinit or stsrm command is executed on the closed files listed below during status service operation, the file status to be displayed by the stsls command will not change:
  • CLOSE
  • NONE
  • BLOCKADE
