You are preparing for the installation of a new CA Product release. You have downloaded the CA Product installation paxfile into a USS File-system and are attempting to unpax the paxfile using the command:
pax -rvf paxfile.pax.Z
The process starts but quickly fails with the message:
pax: decompress: FSUM6639 compressed file is corrupt
There are generally only a few things that can go wrong.
