Allows you to skip by file mark or by record. This tape positioning qualifier is for use on local SCSI tape drives only. Displays information about the operations performed on the magnetic tape volume. Controls whether soft errors on the specified device are to be logged in the error log file.
Soft errors are errors corrected by the hardware without software intervention.
This qualifier affects only devices that support hardware error correction, such as the TU78 magnetic tape drive. When used with other devices, this qualifier has no effect. Controls whether data records are automatically compacted and blocked together on a TA90E tape drive. Data compaction and record blocking increase the amount of data that can be stored on a single tape cartridge. Note that once data compaction or noncompaction has been selected for a given cartridge, that same status applies to the entire cartridge.
