backup aborted

hi all

I am getting following error while taking backup
using the command

ufsdump  0ubf  512 /dev/rmt/0cbn /database/backup2/rman_backup/level0 >> /database/backup2/backup_tape/level0_rman_06sep12 2>&1;

from the log i got the error

bash# tail -f level0_rman_06sep12
  DUMP: Date of this level 0 dump: September  6, 2012 10:51:08 AM IST

At first glance, it looks like you started the command as a foreground process and hit Ctl-C to terminate the dump so you could start tail to watch the progress of the dump you just terminated. Another possibility is that someone else killed your dump. However, it happened, the last line of the tail output seems to indicate that the dump was terminated by a SIGTERM signal.

I agree with @Don_Cragun.

I notice that you are writing to a non-rewind device /dev/rmt/0cbn . As this is a 180 Gb dump level 0 dump, do you want to append to the tape, or would it be better to rewind the tape first (or use the reqind device)?

hi Don Cragun, methyl thanks for your replay.
i re fired the backup today it completed successfully.
thank you.
