Patch Description: s700 10.20 EISA Datakit 3.20.02 Cumulative Patch

Creation Date: 99/05/11

Post Date:  99/06/10

Hardware Platforms - OS Releases:
	s700: 10.20

Products:
	93303J: 3.20.02

Filesets:
	EisaDatakit.DKIT-KRN EisaDatakit.DKIT-RUN

Automatic Reboot?: Yes

Status: General Release

Critical: No

Path Name: /hp-ux_patches/s700/10.X/PHNE_18578

Symptoms:
	PHNE_18578:
	The Datakit dkserver process hangs if it cannot
	connect to a Datakit switch module that is out
	of service.

	PHNE_18297:
	The datakit listener does not start automatically following
	a reboot from single user mode, on certain systems
	(e.g. C-200 database server).

	PHNE_17578:
	EISA Datakit (93303J) version of PHNE_16118 for
	NIO Datakit (93302PD).

	When logged into a system via the datakit network,
	sometimes an application's or user's commands do not
	complete, i.e., a hang occurs.

	tty recursion can happen which will
	cause panic with "Kernel stack overflow".

	Datakit channels shutdown, causing datakit
	sessions to abort and restarting Datakit Server
	with message "ERROR dkmgr: Server <name> end
	of file, restarting".

	A nuisance error message can sometimes be
	seen in the dksrvlog file:
	"ERROR 25640 setting module type".

	Datakit can cease to work, with console
	(/var/adm/syslog/syslog.log) messages as follows:
	vmunix: dkgetcf(0): no chunk of size 32 bytes

	PHNE_17219:
	The datakit listener does not start automatically following
	a reboot from single user mode.

	The previous patch PHNE_14303 could overwrite customizations
	in a user's /etc/opt/dk/dksrvtab file.

	PHNE_14303:
	The dksrvtab file references nonexistent /etc/authorize
	executable instead of /opt/dk/bin/authorize executable.

Defect Description:
	PHNE_18578:
	Previous patch PHNE_18297 removed a timeout
	needed to detect an out-of-service Datakit module.
	Resolution:
	Restore timeout to dkserver.
	Add additional checks to listener to ensure
	that the dkserver is fully initialized before
	the listener is started.

	PHNE_18297:
	Previous patch PHNE_17219 had a one-minute timeout
	when waiting for dkserver to finish initializing.
	This failed when dkserver took longer than one minute
	to initialize on heavily loaded systems (e.g. C-200
	database server).
	Resolution:
	Remove one-minute timeout.

	PHNE_17578:
	EISA Datakit (93303J) version of PHNE_16118 for
	NIO Datakit (93302PD).

	A tty read was not always posted correctly
	in the code.  Furthermore, the tty timeout
	routine was not getting scheduled correctly.

	tty control operations and timeout
	operations on invalid channel 0.
	Time given for "stuck" xmit fifo to drain needed
	to be increased.

	Memory leaks in use of Datakit memory buffer.

	Resolution:
	Migrate NIO Datakit patches to EISA Datakit.

	PHNE_17219:
	The dkserver daemon is not fully initialized when
	the listener starts.
	Resolution:
	Do not start listener until dkserver is initialized.

	The previous patch PHNE_14303 overwrote the
	/etc/opt/dk/dksrvtab file.
	Resolution:
	Overwrite /etc/opt/dk/newconfig/dksrvtab file instead,
	not the active /etc/opt/dk/dksrvtab file.

	PHNE_14303:
	Wrong file names in dksrvtab file.

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 PHNE_18578

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_18578.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_18578.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_18578.  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_18578.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_18578.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	SUBSYSTEM_SHUT
	After installation, in order for the dksrvtab changes to
	be effective in the active file, /etc/opt/dk/dksrvtab:
	1. Shutdown Datakit (/opt/dk/sbin/dkitrc stop).
	2. Merge /etc/opt/dk/newconfig/dksrvtab into
	   /etc/opt/dk/dksrvtab, including any local
	   customizations if required.
	3. Reboot or restart Datakit (/opt/dk/sbin/dkitrc start).
