AIX-on ilyesmit vélek látni a manuálban:
-i Ignores header checksum errors. The tar command writes a file header
containing a checksum for each file in the archive. When this flag is
not specified, the system verifies the contents of the header blocks by
recomputing the checksum and stops with a directory checksum error when
a mismatch occurs. When this flag is specified, the tar command logs
the error and then scans forward until it finds a valid header block.
This permits restoring files from later volumes of a multi-volume
archive without reading earlier volumes.
