Checking Tapes After a Logical-Log Backup (ON-Archive and ontape)
Use
After a logical-log backup with
ON-Archive or ontape , perform the check described below. This makes sure that the tapes can be read successfully, if you need to do a restore. For more information about performing a restore, see Restore.Procedure
$ ondatartr ‘LIST/TAPE=(<tape device>)’
For example, if your tape device was
dev/rmt/0m , you would enter:$ ondatartr ‘LIST/TAPE=(dev/rmt/0m)’

A faulty tape could endanger the integrity of your database. If you need to do a restore and you use a tape that has failed the legibility check, the restore will fail.
