For network attached archive/analyze activities you want to use:
"CHECKSUM=2" on the archive
"CHECKSUM=1" and the analyze
Below is a snippet of I received from NCR on checksum processing, if you have time to run an analyze then it is definitely worth
it:
In the case of ARCMAIN running on UNIX, our archive failures are happening when the data is transferred to tape, so the archive should be
run with CHECKSUM=1. The only way to validate the integrity of the tape archive is to read it back in a separate job with the CHECKSUM=2.
This is a great benefit, as now (for the first time) you can be certain that your archive is valid at a packet level without actually
restoring it.
