Tape Devices

[Nick D'angelo_3]

Last week, I had to reboot my d350 and if I remember correctly, I issued the
reboot or shutdown -r command which will rebuild my device files.

Now, I seem to have lost access to my tape drives.

There is a command to re-create these devices, but I can not remember it.

Any help/suggestions?

There are several methods to restore device files. It really depends on
exactly what symptoms you are experiencing. Are the devices being discovered
by your system but the device files have vanished? This is unusual, as old
device files are not generally purged automatically. Or has the system failed
to autodiscover the devices? You can verify whether the devices are being
pysically recognized with:
ioscan -fnC tape
will show you what tape devices have been discovered by the kernel. If the
devices are there but the device files are not, they can be recreated manually
with mksf or mknod (see the man pages for each). To create the files manually,
you will have to know the appropriate major numbers for the tpe device you are
addressing. You can also use insf to automatically install the drivers. If
you use insf -e, which will autoimatically restore drivers for all discovered
devices, it is generally recommended to go to single-user mode first. I would
recommend trying:
insf -C tape
first, if you choose to go that route.
