Tape Verification (TVerify<ISeq>)
Under various conditions, a tape file container can become (or appear to be) corrupt. These two functions attempt to validate the contents or (at least) determine where things in the input stream may be broken. Using other tools, it may be possible to repair the tape file container but these two subcommands can help verify that the container structure is sound (or not) and that the block sequence numbers/checksums that are expected, have the right values.
Sample Output (TVerify)
TVerify scans the entire input tape container stream and writes diagnostic information to
Here is sample output from the first 100 records of an arbitrary deadstart tape:
Sample Output (TVerifyISeq)
TVerifyISeq subcommand is far less 'chatty' and display the minimum amount of information. It is similar to TVerify in that it attempts to validate the integrity of the sequence number/checksum information on each block. Using the same sample deadstart tape, this is the subcommand's output:
If any errors are found - more diagnostic information is displayed.
