	PHNE_11707: CORRUPTION
		It has a fix for data corruption, a reset panic, a
		a bootup panic, a hang and transmit underruns.

Path Name: /hp-ux_patches/s700/10.X/PHNE_11707

Symptoms:
	PHNE_11707:
	NOTE: In this document, DART 32 refers to the Application
	      Release of March 1997.
	1. Data written from non-coherent NFS clients gets badly
	   corrupted when UDP checksumming is turned off. With UDP
	   checksumming turned on, data transfer rate is very slow.
	2. EISA FDDI interface hangs when EISA bus is stressed.
	3. lanadmin reset panics sometimes; hangs at times.
	4. Transmit underruns occur when the EISA bus is loaded.
	5. ServiceGuard fails to startup with DART 32 EISA FDDI.
	6. If there is EISA FDDI traffic destined for a host while
	   it is booting up, the host may panic.

Defect Description:
	PHNE_11707:
	1. Open GL requires that drivers do not assume that the
	   data buffers they handle will be in space ID 0. As NFS
	   passes down buffers with non-zero space ID to the driver,
	   cache flushes performed assuming space ID 0 result in the
	   intended data not being flushed.
	2. FDDI interface goes into CB running state under stress
	   testing.
	3. In the reset sequence, freeing an already freed mbuf
	   panics the system. Also, driver support for the card
	   reset operation was not adequate.
	4. Under heavy load, the EISA bus is not able to supply
	   outbound data at the rate expected by the FDDI link, thus
	   requiring packets to be cached in on-board memory before
	   sending on the wire.
	5. ServiceGuard requires the first word in the
	   mib.ifDescr field to be the interface name and
	   unit number, e.g., lan0.  Unfortunately, DART 32
	   replaced the word with fddi0.  ServiceGuard
	   attempted to find an interface named fddi0 and
	   failed.
	6. Interrupts are enabled and the inbound path is
	   initialized in the driver before IP initializes
	   the ipintrq.  If there is traffic destined for the
	   host on the EISA FDDI interface before IP gets a chance
	   to initialize ipintrq, the interrupt service
	   routine in the driver attempts to lock the ipintrq
	   and enqueue the packet and this results in a panic.
	   The solution is to discard IP/ARP packets unless the
	   interface is configured up (IFF_UP is set).

Installation Instructions:

	------------------------------------------------------------
	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 PHNE_11707

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_11707.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/PHNE_11707.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/PHNE_11707.  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 PHNE_11707.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/PHNE_11707.depot of=/dev/rmt/0m bs=2k
