- I've been having some trouble recently trying to understand an
- error which pops up during a backup procedure on our SparcStation 2
- running SunOS 4.1.1. This error seems to surface when using
- /usr/etc/dump or /bin/bar. An error is displayed to the console,
- and an error of sorts is sent to root via mail.
-
- The console error resembles the following:
-
- st0 Error for command 'write', Error level: 'Fatal'
- Block 17640 File Number: 0
- Sense Key: Media Error
- Block 17640 File Number: 0
- Sense Key: Media Error
-
- st0 Error for command 'write file mark', Error level: 'Fatal'
- Block 17640
- Sense Key: Media Error
- bar: Insert Volume 2 and press Return when ready.
-
-
- The mail message to root resembles the following:
-
- bar: Insert Volume 2 and press Return when ready.
- bar: Insert Volume 3 and press Return when ready.
-
- Sometimes the above error repeats up to 5 times, and when I verify
- the data on the tape using /bin/bar tvf /dev/rst0, it's there!.
- What I don't understand is why when cron runs the script backup,
- an error is produced when the end of the tape is reached.
- The error is also encountered when using dump.
-
- As per the instructions in the Network Administration Manual
- (Chapter 6 / File Maintenance):
-
- A Sample Dump for using QIC-150
-
- # /usr/etc/dump 0cdtsf 1250 18 570 /dev/rst0 /dev/r_partition
-
- Still produces an error which states:
-
- Dump: Tape write error 691 feet to tape 1
- Dump: NEEDS ATTENTION: Do you want to restart?
-
- I don't understand why a brand new 3M tape would have this problem,
- why would dump try to write 691 feet to a tape 600 feet long using
- 570 as the default length.
-
- Any assistance or insight into these errors would be appreciated.
-
- Thank You in Advance. :-)
