DLT 7000 QuantumTape Drive

[costiles]

Does anyone know the commands to make this tape drive go to the second and ensuing tapes using the aix bacup command. I would assume it is a combination of chdev - but I don't know the combinations.

What device driver do you use for this tapedrive?

Also: what does

lsattr -E -l rmtX

show?

I would guess you also need to put the device itself in autoloading mode...

This is the result of lsattr -E -l rmtX

mode yes Use DEVICE BUFFERS during writes True
block_size 0 BLOCK size (0=variable length) True
extfm no Use EXTENDED file marks True
ret no RETENSION on tape change or reset True
density_set_1 27 DENSITY setting #1 True
density_set_2 26 DENSITY setting #2 True
compress yes Use data COMPRESSION True
size_in_mb 35000 Size in Megabytes False
ret_error no RETURN error on tape change or reset True

The device itself is in autoloading mode...
Thanks for your reply!!!
Hope this will help you point me in the right direction!

I don't think the device driver you have for this tapedrive supports multivolume backups.

I would have expected an attribute like autoload on IBM Atape device driver (e.g. for IBM3590 tapedrive):

# lsattr -E -l rmt0
mode yes Use Buffered Writes True
block_size 0 Block Size (0=Variable Length) True
compress yes Use Hardware Compression on Tape True
autoload yes Use Autoloading Feature at End-of-Tape True
logging no Activate volume information logging True
max_log_size 500 Maximum size of log file (in # of entries) True

Perhaps you are using the driver for a non-autoloading DLT7000 model?

I believe that you must be right - p5wizard. Thanks for the tip. We only have one box with this equip on it and I had no idea what the device looked like to AIX! Thanks very much!

 

[costiles]

I cannot find a driver for this device on any of the AIX media - and the Quantum Web Site does not have a downloadable driver either. ANyone know what gives with this device?

 

[p5wizard]

Checked out the website downloads.quantum.com - there is an AIX installation guide, but no driver for AIX.

manual says on aix cannot be used as a mini library (i.e. you cannot send mount/unmount/position commands) but you should be able to use the device in sequential mode...
