This cryptsetup version doesn't support LUKS. I think some recent cryptsetup versions can be compiled on RHEL4, but it will not work because of missinf some kernel functionality. You can translate mapping to dmsetup commands (cryptsetup create is basically just wrapper over this) but RHEL4 kernel will probably be missing XTS mode or some IV, and for CBC mode is missing ESSIV which is default for LUKS. RHEL4 is EOL already. Do not use it for LUKS. (For RHEL5 there is cryptsetup-luks package.)
