Ripro Backup (Legato)

Recovering the Bad Legato DLT Tape

This procedure is to be used only in cases when the tape is getting the first block surface errors - meaning it is completely unreadable.

1. Load the tape, make it appendable, write a small file to it using the save command.
2. Run dd command on the first blocks to destroy directory header:

   #dd if=/dev/rmt3 of=/dev/null bs=300k

   (reading the first block by dd command actually destroys it)

3. When you then unmount the dlt tape from Legato, Legato will recreate the directory on the DLT tape.
