• Using ontape, in the IBM Informix Backup and Restore Guide
• LTAPEBLK

TAPEBLK specifies the block size of the device to which ontape writes during a storage-space backup. TAPEBLK also specifies the default block size of the device to which data is loaded or unloaded when you use the onload or onunload utilities. If you are using onload or onunload, you can specify a different block size on the command line.

The database server does not check the tape device when you specify the block size. Verify that the TAPEBLK tape device can read the block size that you specify. If not, you might not able to read from the tape.
