Kernel parameters on IPF kernels are different from PA kernels. SAM will not display a description or proper help for these new parameters, but customers will be able to modify their values. These new parameters include:

In this release, DPS is not supported by SAM or the underlying components of the operating system. You can use the Printers and Plotters area of SAM to manage printers or use HP-UX commands instead.

Dump device configuration is not supported in SAM on IPF. You can use other means from outside of SAM to configure dump devices.

SAM is not compiled natively on IPF. It is still a PA-RISC application and uses a PA emulator for operation. Because of the emulation mode, SAM's performance will be degraded from what customers have seen on previous HP-UX releases. An IPF-based native version will be available in a future release that will improve performance.
