		Hewlett Packard strongly recommends that you run the
		utility contained in this patch to determine if your
		system is susceptible to the PCI I/O defect.

Path Name: /hp-ux_patches/s700/10.X/PHSS_12295

Symptoms:
	PHSS_12295:
	HP has discovered a potential system defect that can affect
	the behavior of five models of HP VISUALIZE Workstations
	when equipped with third-party or customer-installed PCI I/O
	cards.  The defect is limited to the HP C180, C160, C160L,
	B160L and B132L VISUALIZE workstations, and will only be
	encountered when data is transmitted through PCI I/O
	expansion cards on the PCI bus.  HP-supplied graphics cards
	that utilize the PCI bus are not affected.
	    Although it is improbable that you will encounter this
	defect, it could result in inconsistent system behavior such
	as system hangs, LAN time-outs, and loss of data integrity.
	Since HP and third parties have only recently introduced PCI
	expansion cards, the number of affected systems should be
	extremely low.

Defect Description:
	PHSS_12295:
	A defect in the PCI I/O controller chip in certain HP
	VISUALIZE Workstations can cause inconsistent system
	behavior when third-party or customer-installed PCI I/O
	cards are used.

Installation Instructions:

	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,

	before installing this patch.
	------------------------------------------------------------
	1. Back up your system before installing a patch.

	2. Login as root.

	3. Copy the patch to the /tmp directory.

	4. Move to the /tmp directory and unshar the patch:

		cd /tmp
		sh PHSS_12295

	5a. For a standalone system, run swinstall to install the
	    patch:

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHSS_12295.depot

	5b. For a homogeneous NFS Diskless cluster run swcluster on the
	    server to install the patch on the server and the clients:

		swcluster -i -b

	    This will invoke swcluster in the interactive mode and
	    force all clients to be shut down.

	    WARNING: All cluster clients must be shut down prior to the
		     patch installation.  Installing the patch while the
		     clients are booted is unsupported and can lead to
		     serious problems.

	    The swcluster command will invoke an swinstall session in which
	    you must specify:

		alternate root path  -  default is /export/shared_root/OS_700
		source depot path    -  /tmp/PHSS_12295.depot

	    To complete the installation, select the patch by choosing
	    "Actions -> Match What Target Has" and then "Actions -> Install"
	    from the Menubar.

	5c. For a heterogeneous NFS Diskless cluster:

		- run swinstall on the server as in step 5a to install
		  the patch on the cluster server.

		- run swcluster on the server as in step 5b to install
		  the patch on the cluster clients.

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHSS_12295.  If you do not wish to retain a
	copy of the original software, you can create an empty file
	named /var/adm/sw/patch/PATCH_NOSAVE.

	Warning: If this file exists when a patch is installed, the
	         patch cannot be deinstalled.  Please be careful
		 when using this feature.

	It is recommended that you move the PHSS_12295.text file to
	/var/adm/sw/patch for future reference.

	To put this patch on a magnetic tape and install from the
	tape drive, use the command:

		dd if=/tmp/PHSS_12295.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	This patch only needs to be applied to the HP C180, C160,
	C160L, B160L and B132L VISUALIZE Workstations.  After you
	have installed this patch, execute the command:
	        /usr/lbin/sysadm/pci_check
	to determine if your system is susceptible to the PCI I/O
	defect.
