If the Attention LED is still blinking after cleaning the head, repeat the operation with

 

a different tape. If this clears the signal, the first tape is nearing the end of its life.

 

Blinking of the Attention LED is cleared when a new tape is loaded or when the drive

 

is power-cycled.

Tape cartridge information

This tape drive supports 60 m, 90 m, 120 m or 125 m DDS cartridges as shown in Table 11.4 .

Note: The compressed capacity is assuming a data compression ratio of 2:1.

When specifying the data format to be used (native or compressed) for your DAT unit, use the following device codes:

native /dev/rmt/xl[n]

compress /dev/emt/xc[n]

Where x refers to the number specific to your system. To get this number, look in the /dev/rmt directory to find the entry that corresponds to the SCSI ID 5.

[n] is an optional parameter specifying no rewind.
