-------- NOTE!!!!!!! NOTE!!!!!!!! NOTE!!!!!! ----------------

This is a HOT-FIX delivery. It is not recommended to use these
binaries on production machines after the main stream patch is 
released and it is intended for use only with specific VXVM and 
OS versions as specified:

  4.1MP2 on 64-bit Solaris 9 SPARC
  4.1MP2 on 64-bit Solaris 10 SPARC


The 4.1MP2 release notes outline a new feature introduced:

http://support.veritas.com/docs/287682

"The dmp_fast_recovery tunable controls whether DMP should attempt 
to obtain SCSI error information directly from the HBA interface. 
Setting the value to on can potentially provide faster error recovery, 
provided that the HBA interface supports the error enquiry feature. 
If set to off, the HBA interface is not used. The default setting is 
off. Before enabling this tunable, make sure the HBA firmware level 
is supported in the HCL. Enabling this tunable with unsupported 
HBA firmware levels may result in a system panic."

Fixes included with this delivery:

e1123248 - addressed two dmp_fast_recovery defects affecting QLogic 
           HBAs, and exposed the tunable to disable dmp_fast_recovery
           as documented in the MP2 release notes.  NOTE: the default
           is still "on" (release notes incorrectly state default
           is "off" which will be addressed in the Late Breaking News
           as well as future patch Release Notes).  The instructions 
           below outline how this advanced failure detection 
           mechanism can be disabled, which is also covered in the
           MP2 release notes.

====================================================================
To replace existing binaries with new hot-fix binaries
====================================================================

1.) Stop all applications, unmount all filesystems using vxvm, and 
    ensure that vxconfigd isn't running:

	# vxdctl stop

2.) Verify the prerequisite 4.1MP2 patch is installed:

	Solaris 9:

	                 417 executables
	              305494 blocks used (approx)

	Solaris 10:

	                 410 executables
	              300757 blocks used (approx)

3.) Make backup copies of the files to be replaced:

	# mkdir /etc/vx/hotfix_save.d/
	# cp /usr/lib/libvxddl.so /etc/vx/hotfix_save.d/libvxddl.so_orig
	# cp /sbin/vxconfigd /etc/vx/hotfix_save.d/vxconfigd_orig
	# cp /sbin/vxdmpadm /etc/vx/hotfix_save.d/vxdmpadm_orig
	# cp /kernel/drv/sparcv9/vxdmp /etc/vx/hotfix_save.d/vxdmp_orig

4.) Install new files from the appropriate subdirectory, and 
    verify checksums:

	Solaris 9:

	# cd ./4.1MP2_Sol_2.9
	# ls -la /usr/lib/libvxddl.so /sbin/vxconfigd /kernel/drv/sparcv9/vxdmp /sbin/vxdmpadm

	153291219       688912  /etc/vx/hotfix_save.d/vxdmp_orig
	#

5.) Make a copy of the current dmppolicy.info file:

	# cp /etc/vx/dmppolicy.info /etc/vx/hotfix_save.d/dmppolicy.info_orig

6.) Reboot the system (use "init 6" if using PGR fencing):

	# init 6

7.) After reboot, confirm the modinfo string reflects the new dmp module:

	Solaris 9:

	# modinfo |grep vxdmp
 	 33 780f2000  351bb 235   1  vxdmp (VxVM 4.1_MP2.13+e1123248: DMP D)

	Solaris 10:

	# modinfo |grep vxdmp
	 36  12baf88  350b8 308   1  vxdmp (VxVM 4.1_MP2.13+e1123248: DMP D)

	NOTE: only columns 3 and 6+ should match, the others will vary.

8.) Optionally set dmp_fast_recovery to off:

	# vxdmpadm gettune all |grep fast_recovery
	dmp_fast_recovery                        on               on
	# vxdmpadm settune dmp_fast_recovery=off
	Tunable value will be changed immediately
	# vxdmpadm gettune all |grep fast_recovery
	dmp_fast_recovery                       off               on
	#


====================================================================
To back out hot-fix binaries
====================================================================

1.) Stop all applications, unmount all filesystems using vxvm, and 
    ensure that vxconfigd isn't running:

	# vxdctl stop

2.) Restore original backup copies saved during the installation step 3 above:

	# cp /etc/vx/hotfix_save.d/libvxddl.so_orig /usr/lib/libvxddl.so
	# cp /etc/vx/hotfix_save.d/vxconfigd_orig /sbin/vxconfigd
	# cp /etc/vx/hotfix_save.d/vxdmpadm_orig /sbin/vxdmpadm
	# cp /etc/vx/hotfix_save.d/vxdmp_orig /kernel/drv/sparcv9/vxdmp

3.) Verify the checksums:

	Solaris 9:

	# cksum /usr/lib/libvxddl.so /sbin/vxconfigd /kernel/drv/sparcv9/vxdmp /sbin/vxdmpadm
	1202102719      1627292 /usr/lib/libvxddl.so
	2672936104      3254016 /sbin/vxconfigd
	3892661021      1064804 /sbin/vxdmpadm
	1691885207      677272  /kernel/drv/sparcv9/vxdmp
	#

	Solaris 10:

	# cksum /usr/lib/libvxddl.so /sbin/vxconfigd /kernel/drv/sparcv9/vxdmp /sbin/vxdmpadm
	1202102719      1627292 /usr/lib/libvxddl.so
	1605169801      3025104 /sbin/vxconfigd
	3892661021      1064804 /sbin/vxdmpadm
	153291219       688912  /kernel/drv/sparcv9/vxdmp
	#

4.) Restore the original dmppolicy.info file into /etc/vx/ directory:

	# cp /etc/vx/hotfix_save.d/dmppolicy.info_orig /etc/vx/dmppolicy.info

5.) Reboot the system (use "init 6" if using PGR fencing):

	# init 6
