If I remember well there is no -C option in the Solaris 5.8 version of tar. Anyway, if the GNU version of tar is available, the -C option can be used. Try

which gtar
to verify. Otherwise, just move the archive to /SAN_C2D/csp_bakup/ and extract from there.

The reason why the command didn't work is that if you do

tar xvf csp0203.tar /SAN_C2D/csp_bakup
you're trying to extract the file or directory /SAN_C2D/csp_bakup from the archive. Since most likely it didn't exist, the tar command returned nothing. Once you've moved the archive to /SAN_C2D/csp_bakup just do

tar xvf csp0203.tar

From the output of the tar command, it looks like the files inside the archive retain their absolute path (maybe they were created using -P option with GNU tar). Have a look at directory /u13/CSIP0203/.

What is the mistake with extraction? What do you mean for "linked file"? Can you explain a bit more?

And please, don't edit previous posts by erasing them. This make the thread unreadable and confused. Thanks.
