Could you please check the script, customer is using for creating backup and the device files associated with it.

There is possibility that script is issueing a command on a device file which is not supported on that.

For Example:

Using a script to write to the tape device is producing the following message in syslog.log:

vmunix SCSI TAPE: dev=0xcd032040 I/O error during close


The tape and tape drive are both OK.


the script is issuing the mt(1) command
against a no-rewind device file which produced the IO error.
The mt command works best when used with the Berkeley style device file. This is explained in the man page:

WARNINGS: Only raw, no-rewind Berkeley-type devices should be specified. This type of device will not reposition the tape upon close. An example of such a device is /dev/rmt/0mnb. Please refer to mt(7) for more details.

When the /dev/rmt/0mnb device is used, the problem went away.

Hi,

if I remember correctly, this message may appear, when a tape is prematurely ejected while the backup process is still in progress.

Very often this indicates a bad drive ...
