DLT density writing

[u856100]

Hi all,

I am trying in vain, to attempt to create a device file that will constrain the write density of a DLT drive to a density setting of 20.0 (no compression). The options in the man pages seem to indicate that this DLT_xxx setting does not exist. Am I mistaken?

In addition to this, is there a clean way to remove the created device file from /dev/rmt/ so that all created references to this file (if any) are removed.

forever in your debt,

John

Hi,

I'm not sure about your first question.
Below is a link to a thread that is
interesting about creating devices for
different densities. This maybe of help.

To remove the devices, from your ioscan,
remove the path and re-create it using
ioscan again and then insf to create.

# rmsf -H 1/12 (example)
# ioscan -fn
# cd /dev
# insf -e

Hi,

Thanks for the info, much appreciated and it worked fine.

To clarify my question (which I have posed rather ambiguously), I am trying to force the tape, via the device file, to write to a capacity of 20Gb or 10Gb.

Don't know whether this helps?

thanks for your help,

John
