Hello fellow admin's

We have been getting an unusual error/warning message on our backup host
upon the completion of a tape. When a tape becomes full we get the message
about unexpected block size. The tape backup host is configured as follows

Solstice Backup 5.1.1 on SPARC20 running Solaris 7. Three attached tape
drives backing up approx 200GB per week.

0cbn is a Storedge L280 (35/70GB) DLT
1cbn is a DEC/Compaq/HP - TZ887 (20/40GB) DLT
2cbn is a DEC/Compaq/HP - TZ887 (20/40GB) DLT

The errors only happen on the DEC drives and don't appear to cause any
problems. We are able to read/write from them fine and recover file systems
without any errors or issues.

Thisi s just one of those annoying things that you know something is
configured wrong but don't know how to fix and want to get it write. Any one
have any suggestions?

Thanks, Error from daemon.log follows
