Recreate device files due to tar error

[LucianoCarvalho]

Hi Guys!
Does anyone know how to recreate device files on Tru64 5.1? It's because I'm trying to restore a backup through tar with device file /dev/tape/tape1_D0, but I'm receiving the following error:
can not open /dev/tape/tape0_D0: No shuch device or address
The tape drive was changed and swaped to another address some time ago.
The command used on restore:

tar cvf /dev/tape/tape1_D0
Thanks

first, restoring a device from tape etc. is not a supported way.

use the commands

# hwmgr -scan scsi
to automatically detect new scsi devices.

# hwmgr -show scsi
to check if a new device was created

# dsfmgr -m tape5 tape0
to move the name of the tape device

have a closer look to the administration guide dealing with all kind of issues on devices.

The device name is the one that
hwmgr -show scsi
will display a valid path for it.

You can also see it by:
file /dev/tape/*

You can then change the name (by dsfmgr as mentioned before) or use the command with this device name

delete them and re-boot the os will detect and re-create the device files.
