Patch Description: s700 10.20 ccio2 IOpdir cumulative patch (ACE 199912)

Creation Date: 99/09/16

Post Date:  99/12/07

Hardware Platforms - OS Releases:
	s700: 10.20

Products: N/A

Filesets:
	OS-Core.CORE-KRN OS-Core.KERN-RUN

Automatic Reboot?: Yes

Status: General Release

Critical:
	Yes
	PHKL_19721: HANG

Path Name: /hp-ux_patches/s700/10.X/PHKL_19721

Symptoms:
	PHKL_19721:
	The size of the IOpdir used by the ccio2 IO adapter is too
	small for some system configurations.  This can cause the
	system to hang if a heavy I/O load is placed on the system.

	PHKL_17646:
	This patch enables new functionality that is part of the
	10.20 ACE (Additional Core Enhancements) Workstation bundle.
	It adds new I/O drivers to support the B1000, C3000, and
	J5000 systems.  In particular this patch enables the ccio2
	Core I/O adapter and the lba PCI bus bridge.

Defect Description:
	PHKL_19721:
	The IOpdir used by ccio2 is set to a fixed size of 8192
	entries.  On systems with many active I/O interfaces, this
	number may be too small, causing the system to hang.

	Resolution:
	The size of the ccio2 IOpdir is now sized according to how
	much physical memory is installed in the system.  The IOpdir
	size will now be set to 1/16th of physical memory, with a
	minimum value of 8192 entries.

	PHKL_17646:
	New functionality to support the B1000, C3000, and J5000
	systems on HP-UX 10.20.  The Core IO on these systems
	and the system will fail to boot unless this patch is
	present.
	Resolution:
	Add support for the Core IO on B1000, C3000, and J5000
