Symptoms:
	PHCO_16973:
	The trec command is failing for on an HFS disk with no LVM.
	When booting, the message is:
	process_inode: inode number 1865955381 is out of range

	When prompted to run trec interactively:
	process_inode: inode number 196937501 is out of range

	also error

	Read failed: bad address
	unable to read file system data block -2147464877, size=8192
	at -2199004034048(0x01254c00), offset=-512

Defect Description:
	PHCO_16973:
	trec fails on HFS disk - 1GB internal, no LVM. The error
	message indicated a value out of range. Becaues of this,
	the disk would not boot automatically and you were supposed
	to run trec manually. This would fail, but after CTRL-D to
	exit the shell, the machine would boot and no strange
	behavior was observed.

	Resolution:
	The values that were originally out of range seemed to be
	things that should have been reconciled by fsck. I first
	looked through the patch list for fsck, and found one for
	11.0 that seemed to address the same problem (PHCO_16703).
	I ported that patch first, which when run made some changes
	on the disk during the fsck. But trec was still hosed. So -
	I finally determined that the call to the lseek64 routine
	had a parameter that was being interpreted as an int, was
	supposed to be a 64-bit off_t.

Installation Instructions:
	Please review all instructions and the Hewlett-Packard
	SupportLine User Guide or your Hewlett-Packard support terms
	and conditions for precautions, scope of license,
	restrictions, and, limitation of liability and warranties,
	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_16973

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHCO_16973.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_16973.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_16973.  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_16973.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_16973.depot of=/dev/rmt/0m bs=2k
