ontape restor failed

dear informix-group during the restore of our main ids server on the test ids server following message occured: physical restore failed - the archiv backup is corrupted what does it mean. could there be an error by the tape or tape-device? we build on the test machine the same raw devices and dbspaces as on the main machine. thank for your help. markus scheer Sent via Deja.com http://www.deja.com/ Before you buy.
