(Tunable Kernel Parameters)

NAME

physical_io_buffers - total buffers for physical I/O operations

DESCRIPTION

This tunable was used in HP-UX 11i Versions 1.6 and 2.0 to size a shared pool of buffers for physical I/O

operations in the kernel.

As of HP-UX 11i Version 3.0 and later, the kernel automatically manages the pool size. This tunable is

no longer needed and is obsolete as of HP-UX 11i Version 3.0.

WARNINGS

All HP-UX kernel tunable parameters are release speciﬁc.

Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parame-

ter values. After installation, some tunable parameters may no longer be at the default or recommended

values. For information about the effects of installation on tunable values, consult the documentation for

the kernel software being installed. For information about optional kernel software that was factory

installed on your system, see HP-UX Release Notes at
