DLT tape drive on an N-Class

[John Paine]

Hi All,
I am tar'ing files to a DLT and have noticed the maximum block size allowed (OS11.0)
is 64 - which seems a bit small.Does anyone know if there is a patch to increase block size to say, 512?
Thanks,
John.

Hi John,

Take a look at this thread.

Link has been changed to the latest version of gnu tar.

Hope this helps,

What type of DLT drive are you using ?

What level of patching do you have for SCSI and stape patches ?

The stape patches are where you are most likely to find a fix for something like this.

Finally, what commands are you using to write out to the DLT ?

Best regards,

Thanks for replying Robert-Jan and Kent.
I am writing to a Quantum SDLT600 - which BTW
I can write to using 1024 and 512 block sizes from a Linux PC system so I know it works.The command I am currently using is:-
tar -cvbf 64 /dev/rmt/xx /ts28 which is at the moment tar'ing a 210Gb file system to tape.My latest stape patch is PHKL_29898 which I swinstalled last week to allow the writing of very larg files over 100Gb.
I will try to follow the link to the GNU site although I did try to follow one earlier from a thread by the Guru himself - Mr Stephenson but got page not found.

Regards,
John.
