	SR 1653234476 / DTS TPO0h01652
	Enhancement request for ITU/T 1988 Throughput class support

Defect Description:
	PHNE_15363:
	DTS TPO0h02089
	Under extremely high loads, the ACC DAM can sometimes be
	reentered while it is currently executing on the ICS.
	The ACC DAM is not designed to be reentrant (it is MP
	SAFE).  The AXIN driver was lowering the interrupt level
	when it should not have been allowing the ACC DAM to be
	reentered.  The AXIN driver was modified to maintain a
	high SPL level when executing on the ICS.

	PHNE_13996:
	SR 1653234476 / DTS TPO0h01652
	Configure 64K Throughput Class doesn't get accepted

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_15363

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

		swinstall -x autoreboot=true -x match_target=true \
			-s /tmp/PHNE_15363.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_15363.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_15363.  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_15363.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_15363.depot of=/dev/rmt/0m bs=2k

Special Installation Instructions:
	SUBSYSTEM_SHUT
	Before installing this patch, use the following command
	to shutdown the ACC subsystem and kill the ACC daemons.

	   /opt/acc/bin/zmasterd kill

	The above command kills any of the ACC daemons that are
	still running, including zmasterd, zx25d, watch, zmlog,
	zmon, and znode.

	The kernel will be regenerated and the system will reboot
	automatically during the patch installation.
