Failed to open tape device

[Carlos Munoz Lopez]

Hi guys. I'm having the following problem: I was trying to execute the following command make_tape_recovery -Av -l -x inc_entire=vg00 -a /dev/rmt/3mn, but it displays an error "Failed to open tape device /dev/rmt/0mn:No such device or address
(errno = 6)." I don't know why it shows 0mn, even if this is not the device I specify in the command line. I would like some help on this.

Hi

Is your tape write protect

If not

Use
lssf /dev/rmt/*

To check for the device files

Looks like

If there are any problems use sam to remake the device files for the drive

Hi,
What you can do is :

#ioscan -fnCtape && insf -e
#ioscan -fnkCtape

this will display the device file.
