StorageWorks SDLT Tape Drive by Compaq Reference Guide

2–7

Operating System Device Drivers

The 

INITIALIZE

 command controls whether data records are automatically 

compacted and blocked together on any device that supports data compaction. Data 
compaction and record blocking increase the amount of data that can be stored on a 
single tape cartridge. 

NOTE:  

Once data compaction or non-compaction has been selected for a given cartridge, that 

same status applies to the entire cartridge.

The format for the 

MOUNT

 command is:

MOUNT

/MEDIA_FORMAT

COMPACTION

Example 1

$ MOUNT/FOREIGN/MEDIA_FORMAT=COMPACTION MKA400: BOOKS

This command performs a foreign mount of a tape with data compaction and record 
blocking enabled and assigns the logical name 

BOOKS

 to the tape.

Example 2

$ INIT/MEDIA_FORMAT=NOCOMPACTION MKA400: BOOKS

$ MOUNT/MEDIA_FORMAT=COMPACTION MKA400: BOOKS

This 

MOUNT

 command attempts a Files-11 mount of a tape labeled 

BOOKS

 with data 

compaction and record blocking enabled. Because the tape was initialized with 
compaction disabled, the 

MOUNT

 qualifier 

/MEDIA_FORMAT=COMPACTION

 has no effect.
