Patch Description: s700_800 10.20 mkboot(1M) and rmboot(1M) patch

Creation Date: 98/03/03

Post Date:  98/03/09

Hardware Platforms - OS Releases:
	s700: 10.20
	s800: 10.20

Products: N/A

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

Automatic Reboot?: No

Status: General Release

Critical:
	Yes
	PHCO_14378: CORRUPTION

Path Name: /hp-ux_patches/s700_800/10.X/PHCO_14378

Symptoms:
	PHCO_14378:
	Dump is disabled ONLY during boot, and no boot lvol after
	cold install.

	PHCO_9014:
	mkboot will write an incorrect year field in the LIF.

Defect Description:
	PHCO_14378:
	The kernel file system change (PHKL_13681 and its
	successors) which allows for better performace with the
	buffer cache and block disk devices creates a problem for
	commands which interact using block and raw devices for
	reading and writing.  The inconsistent use of these devices
	causes a synchronization problem when one command writes
	data to the disk through the buffer cache and a subsequent
	command intentionally overwrites this data by using the raw
	disk device.  When the buffer cache is flushed during a
	reboot, the original data is erroneously restored.

	PHCO_9014:
	The year should have been calculated as year mod 100.

Installation Instructions:

	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 PHCO_14378

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_14378.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/PHCO_14378.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/PHCO_14378.  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 PHCO_14378.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/PHCO_14378.depot of=/dev/rmt/0m bs=2k
