Problem with ontape

Hello, Subject: Problem to make a full level 0 backup of my Database with ontape -s. I use Informix Dynamic Server Version 7.31 on a Linux Suse 10 distribution. I want to make a level 0 backup on a tape on Server test4. Here`s an extract of my onconfig file: TAPEDEV /dev/st0 #Tape device path TAPEBLK 128 #Tape block size (Kbytes) TAPESIZE 20000000 #Maximum amount of data to put on tape (Kbytes) The Read/Write Permissions for ontape: -rwsr-sr-x 1 root informix 1330659 Nov 7 16:08 ontape* When i was trying to run ontape -s -L 0 i receive the following message after pressing return to continue: Could not write archive tape. And then after a few seconds there is an abnormal system hang-up and i must restart the system. I tried this on several Linux Suse 10 Servern, with different tapes and with different tape units. It`s every time the same problem: I receive the message "could not write archive tape" and a few moments later the system hang-up. After this i try to do a remote backup from test1 (another Linux Server with tihe same IDS and SUSE Version as test4) to test4 and i adjust the onconfig file like this: TAPEDEV test4:/dev/st0 #Tape device path With this configuration it works, but the tape unit is still at the Linux Suse System (which is here test4). Why works it when i approach the system remote from remote and why i receive an system hang-up end when i try the same thing directly on the Linux Suse Distribution ? (With tar i can write to tape without any trouble.) Any suggestion is welcomed.

Apart from the security aspect, it is not like a plain tape device which is what TAPEDEV really expects. Try changing the permissions to something that a tape device has : ls -l /dev/rmt total 0 crw-rw-rw- 2 bin bin 205 0x013000 Jan 30 2006 0m crw-rw-rw- 2 bin bin 205 0x013080 May 4 2005 0mb crw-rw-rw- 2 bin bin 205 0x013040 Mar 25 2008 0mn crw-rw-rw- 2 bin bin 205 0x0130c0 May 4 2005 0mnb crw-rw-rw- 2 bin bin 205 0x013000 Jan 30 2006 c1t3d0BEST crw-rw-rw- 2 bin bin 205 0x013080 May 4 2005 c1t3d0BESTb crw-rw-rw- 2 bin bin 205 0x013040 Mar 25 2008 c1t3d0BESTn crw-rw-rw- 2 bin bin 205 0x0130c0 May 4 2005 c1t3d0BESTnb crw-rw-rw- 1 bin bin 205 0x013001 May 4 2005 c1t3d0DDS crw-rw-rw- 1 bin bin 205 0x013081 May 4 2005 c1t3d0DDSb crw-rw-rw- 1 bin bin 205 0x013041 May 4 2005 c1t3d0DDSn crw-rw-rw- 1 bin bin 205 0x0130c1 May 4 2005 c1t3d0DDSnb Not sure when you say "System hangs" you mean IDS or Suse. If it is Suse then ... problem is with Suse.
