StorageWorks 8505 8mm Cartridge Tape Drive

Example:

# lsdev –Cc tape

Name	Status	Location	Description
rmt0	Available	00–03–00–50	Other SCSI Tape Drive

ŽNext, type:

# chdev –l <rmt*> –a density_set_1=<DENSITY_1> –a density_set_2=<DENSITY_2>

Example:

# chdev –l rmt0 –a density_set_1=140 –a density_set_2=20 rmt0 changed

•Finally, type the following:

# chdev –l <rmt*> –a block_size=<SIZE>

Example:

#chdev –l rmt0 –a block_size=1024 rmt0 changed

where,

<rmt*> is the tape drive added as shown by the lsdev command. <SIZE> is the fixed block size (0 = variable, 1024 is suggested). <DENSITY_1> (140 suggested) and DENSITY_2 (20 suggested).
