Status: General Release

Critical:
	Yes
	PHSS_20005: PANIC

Path Name: /hp-ux_patches/s700/10.X/PHSS_20005

Symptoms:
	PHSS_20005:
	1. The fix affects the disk monitor, disk_em, which is used
	as decoder and monitor to decode driver errors for scsi
	disks. Ignores user-defined actions for event generation
	from a configuration file and incorrect events generated
	when an incorrect LUN is detected.

	2. Excessive CPU usage by diagmond

	3. Accumulation of temporary device files in /var/tmp.

	PHSS_19538:
	1. The fix affects the disk monitor, disk_em, which is used
	as decoder and monitor to decode driver errors for scsi
	disks. A system panic reportedly occurs.(This is a rare
	occurrence and has been impossible to reproduce).

Defect Description:
	PHSS_20005:
	1. The tool ignores the user-defined action for generation
	of an event in the disk_em.cfg file for the disk monitor.
	Also, when an incorrect LUN is detected, the monitor
	generates erroneous events. XP256 disk array is one of these
	devices.

	2. A bug which manifests itself as diagmond using 10-20% of
	the CPU time on a system.

	3. This change removes the device file, should access to
	the device fail. This prevents the accummulation of device
	files in the directory /var/tmp.  Additionally, the routines
	within this library verifys the arguments passed to it
	before attempting to assign values to them.

	PHSS_19538:
	1. The tool reportedly resulted in system panic due to trap
	18 in scsi3 driver. (This is a rare occurrence and has been
	impossible to reproduce).
	Also, when an unknown combination of Sense code, key and
	qualifier is received, the code generates message that is
	misleading.

	------------------------------------------------------------
	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_20005

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHSS_20005.depot

	By default swinstall will archive the original software in
	/var/adm/sw/patch/PHSS_20005.  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_20005.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_20005.depot of=/dev/rmt/0m bs=2k
