LTAPEBLK specifies the block size of the device to which the logical logs are backed up when you use ontape for dbspace backups. LTAPEBLK also specifies the block size for the device to which data is loaded or unloaded when you use the -l option of onload or onunload. If you are using onload or onunload, you can specify a different block size at the command line.

Specify LTAPEBLK as the largest block size permitted by your tape device. The database server does not check the tape device when you specify the block size. Verify that the LTAPEDEV tape device can read the block size that you specify. If not, you might not be able to read from the tape.
