Yes, after running the command reboot -- -r I could see now the creation of new devpath /dev/rmt/1cbn, and through the netbackup software i reconnected the missing path to this one. Things are ok so far and the backup started as expected.
I realy appreciate your help.

I have another request collegues.
I am interested to replace a faulty hard disk which is not mirorred. it is containing ex ./dev/vx/rdsk/Vol1 file system.
But i have some ideas in my mind and I wish if you can correct me if wrong
1- backup the files system using ufsdump utility to a tape
ufsdump 0uf /dev/rmt/0m /Vol1
2- umount the file system
3- Replace the faulty hard disk.
4- create new file system on the new hard disk
newfs /dev/rdsk/c1t1d0s0
5- Mount /Vol1 on the ne file system.
mount /dev/dsk/c1t1d0s0 /Vol1
6- Restore from backup.
ufsrestore -rvf /dev/rmt/0m
Are these steps correct particularly point no 4.?

HT(4) Kernel Interfaces Manual HT(4)
NAME
ht - TM-03/TE-16,TU-45,TU-77 MASSBUS magtape interface
SYNOPSIS
/sys/conf/SYSTEM:
NHT ht_drives # TE16, TU45, TU77
/etc/dtab:
#Name Unit# Addr Vector Br Handler(s) # Comments
ht ? 172440 224 5 htintr # tu 16 massbus tape
major device number(s):
raw: 6
block: 0
minor device encoding:
bits 0003 specify HT drive
bit 0004 specifies no-rewind operation
bit 0010 specifies 1600BPI recording density instead of 800BPI
DESCRIPTION
The tm-03/transport combination provides a standard tape drive interface as described in mtio(4). All drives provide both 800 and 1600
bpi; the TE-16 runs at 45 ips, the TU-45 at 75 ips, while the TU-77 runs at 125 ips and autoloads tapes.
FILES
/dev/MAKEDEV script to create special files
/dev/MAKEDEV.local script to localize special files
SEE ALSO
mt(1), tar(1), tp(1), mtio(4), tm(4), ts(4), dtab(5), autoconfig(8)
DIAGNOSTICS
tu%d: no write ring. An attempt was made to write on the tape drive when no write ring was present; this message is written on the termi-
nal of the user who tried to access the tape.
tu%d: not online. An attempt was made to access the tape while it was offline; this message is written on the terminal of the user who
tried to access the tape.
tu%d: can't change density in mid-tape. An attempt was made to write on a tape at a different density than is already recorded on the
tape. This message is written on the terminal of the user who tried to switch the density.
tu%d: hard error bn%d er=%b ds=%b. A tape error occurred at block bn; the ht error register and drive status register are printed in
octal with the bits symbolically decoded. Any error is fatal on non-raw tape; when possible the driver will have retried the operation
which failed several times before reporting the error.
BUGS
If any non-data error is encountered on non-raw tape, it refuses to do anything more until closed.
The system should remember which controlling terminal has the tape drive open and write error messages to that terminal rather than on the
console.
