Install/Uninstall Instructions:
===============================
=======================
Installation Procedure:
=======================

If the currently installed VRTSvxvm is below 5.1.100.0 level,  
upgrade VRTSvxvm to 5.1.100.0 level before installing this patch.

AIX maintenance levels and APARs can be downloaded from the
IBM web site:

1. Since the patch process will configure the new kernel extensions,
ensure that no VxVM volumes are in use or open or mounted before
starting the installation procedure

2. Check whether root support or DMP native support is enabled. If it is enabled, it will be retained after patch upgrade.

# vxdmpadm gettune dmp_native_support
If the current value is "on", DMP native support is enabled on this machine.
# vxdmpadm native list vgname=rootvg
If the output is some list of hdisks, root support is enabled on this machine

3.
	a. Before applying this VxVM 5.1 SP1P2 patch, stop the VEA Server's vxsvc process:
	# /opt/VRTSob/bin/vxsvcctrl stop

	b. To apply this patch, use following command:
	# installp -ag -d ./VRTSvxvm.bff VRTSvxvm

	c. To apply and commit this patch, use following command:
	# installp -acg -d ./VRTSvxvm.bff VRTSvxvm
	NOTE: Please refer installp(1M) man page for clear understanding on APPLY & COMMIT state of the package/patch.

	d. Reboot the system to complete the patch upgrade.
	# reboot

	e. Confirm that the point patch is installed:
	# lslpp -hac VRTSvxvm | tail -1
	/etc/objrepos:VRTSvxvm:5.1.100.200::APPLY:COMPLETE:01/02/11:10;56;11

	f. if root support or dmp native support is enabled in step 2, verify whether it is retained after completing the patch upgrade
	# vxdmpadm gettune dmp_native_support
	# vxdmpadm native list vgname=rootvg

==========================
De-installation Procedure:
==========================

1. Check whether root support or DMP native support is enabled or not:

	# vxdmpadm gettune dmp_native_support
If the current value is "on", DMP native support is enabled on this machine.
	# vxdmpadm native list vgname=rootvg
If the output is some list of hdisks, root support is enabled on this machine

If disabled: goto step 3.
If enabled: goto step 2.

2. If root support or DMP native support is enabled:

	a. It is essential to disable DMP native support.
	Run the following command to disable DMP native support as well as root support
	# vxdmpadm settune dmp_native_support=off

	b. If only root support is enabled, run the following command to disable root support
	# vxdmpadm native disable vgname=rootvg

	c. Reboot the system
	# reboot

	d. Before backing out patch, stop the VEA server's vxsvc process:
	# /opt/VRTSob/bin/vxsvcctrl stop

   To reject the patch if it is in "APPLIED" state, use the following command and re-enable DMP support
	# installp -r VRTSvxvm 5.1.100.200

	a. Reboot the system
	# reboot

	b. Enable DMP native support, this will also enable root suppport
	# vxdmpadm settune dmp_native_support=on

	c. Reboot the system.
	# reboot

	d. Verify DMP native or root support is enabled:
	# vxdmpadm gettune dmp_native_support


   To remove the patch if it is in "COMMITED" state, use the following command and re-enable DMP support

	# installp -ug VRTSvxvm

	a. Install previous VxVM package version. Install base VxVM package and any dependent packages

	b. Run vxinstall to start the processes
	# vxinstall

	c. Enable DMP native support, this will also enable root suppport
	# vxdmpadm settune dmp_native_support=on

	d. Reboot the system.
	# reboot

	e. Verify DMP native support has been enabled:
	# vxdmpadm gettune dmp_native_support


3. If root support or DMP native support is not enabled

	a. Before back out patch, kill the VEA Server's vxsvc process:
	# /opt/VRTSob/bin/vxsvcctrl stop

   To reject the patch if it is "APPLIED state, use the following command

	# installp -r VRTSvxvm 5.1.100.200
	Reboot the system
	# reboot

   To remove the patch if it is "COMMITED" state, use the following command

	# installp -ug VRTSvxvm
	a. Reboot the system
	# reboot

	b. Install previous VxVM package version. Install base VxVM package and any dependent packages

	c. Run vxinstall to start the processes
	# vxinstall
