Stop activity to all SFHA volumes. For example, stop any applications such
as databases that access the volumes, and unmount any file systems that
have been created on the volumes.

If fencing is configured with VCS, you must disable fencing before proceeding
to upgrade.
To disable fencing, perform the following steps:
■ If the cluster-wide attribute “UseFence” is set to SCSI3, then reset the
value to NONE in the /etc/VRTSvcs/conf/config/main.cffile
■ On each node, edit the /etc/vxfenmode file to configure vxfen in disabled
mode.
# cat /etc/vxfenmode
vxfen_mode=disabled
■ Stop I/O fencing on each node:
# /sbin/init.d/vxfen stop
# /sbin/vxfenconfig -U

Upgrade the HP-UX operating system to the latest available HP-UX 11i v3
fusion release.

If patches to HP-UX 11i v3 are required, apply the patches before upgrading
the product.
