Further Command Information

arguments, refer to the tar man page by typing the following:
man tar
The man utility looks up man pages on the system.
You may also communicate with the tape drive with the cpio, ftio, mt, and
fbackup commands. For more information on these commands, enter the

Media Interchangeability Restrictions
If you interchange media between DDS-format tape drives, the following
two restrictions apply to the media:
• Data cassettes with compressed data can only be read by tape drives which have
data compression capabilities, such as the tape drive (part number C1504-67201)
found in Kit A2275A #AHS. This includes data cassettes that contain both com-
pressed and noncompressed data.
• Use 90-meter data cassettes only in the 3.5-inch form factor DDS-format tape
drives found in Kit A2274A #AHS (part number C1503-67201) and Kit A2275A
#AHS (part number C1504-67201). The full height (5 1/4-in) DDS-format tape
drives cannot read or write to 90-meter data cassettes.
