A backup is done every night through crontabs. However it does not copy all the files like it is suppose to. Close to the end as it copying all the files it will stop and show : “Cpio: can’t open /dev/tty for writing” ( this is shown through an email sent to root from cron). I’ve verified that not all the files not being backed up. This problem occurred from one day to the next after error message one morning: Cha: scsi bus has been reset ha=0 Attached scsi peripherals will return to power up state (chaNo4) Cha: scsi command timed out ha=0 id=6 lun=o cmd=15 blk=0 len16 A scsi peripheral failed to report completion status in time (chaNo5) If I do a command “tape amount” after the backup has stopped it will show exactly 2805696k everyday. Seems like its coping only so much???????? I have ran system utilities and rebooted. Running SCO_SV 3.2 5.0.5 i386 Exabyte tape drive I have changed tape blk to 0 for variable. The kernel parameter CTBUFSIZE is set to 128k I use Maxell HS 8/160 8mm, capacity 3.5 /7.gigabytes compressed Command dfspace shows: / 183.47 MB of 7935.06 MB available /stand 566MB of 14.99 MB available The actual backup command in the script is: /bin/find / -print | cpio –ocvB –K 7000000 –O/dev/rStp0 Any suggestions out there? I suppose something needs to be changed back. I’m stompted.

I may be way of key here, but the process is not trying to backup itself is it? eg. /dev/tty whatever is the device that is actually running the backup and your scipt is asking it to back that file up as well??? I assume you are using /dev/rStp0 as the tape device?

Hello, To me it looks like you are running out of tape (ie. backing up more data than can fit onto the tape). You are getting the message cannot open tty is because it is asking you to type in the next device name (for multi volumes). Regards, Anthony.

Hi! Can you please help me? I'm a newbie in SCO Openserver Unix (5.05) I'm currently producing a Disaster Recovery Plan. After reading most of the material for SCO, it is stated that cpio, backup, or the Backup Manager are the commands or utils to use for filesystem backups. I agree but some of my colleagues say they just use tar. What should I use? Another thing, I know this may be the most basic of questions but here goes: I have two hard disks: the 1st one contains root and most Unix apps, the 2nd one has around 5 partitions (raw devices) being used as dbspaces for a database. Now I need to backup all the hard disks (complete monthly filesystem backup). If I backup the root filesystem, will this also backup all other filesystems on the 1st disk (eg /u, etc) and all the partitions on the 2nd disk. My logic is all devices are in the /dev directory which is under the root directory (/). Anuthing wrong with this??? Thanks for your help!:)
