20 SCSI Module Driver Event
Messages (ZSMD)
The SMD subsystem returns syndrome codes to the input/output processes (IOPs)
(disk, tape, and so on) that communicate with SCSI devices. The IOPs, in turn,
generate SCSI common events. The SMD event messages are reported to the EMS
service event logger ($ZLOG). These messages are viewable using the OSM Event
Viewer or the TSM EMS Event Viewer Application. SCSI module driver event
messages are reported to the EMS by the DP2 Driver.
