Before you upgrade, perform the following procedure.
To prepare for the Live Upgrade
Make sure that the Storage Foundation installation media and the operating system installation images are available and on hand.
On the systems to be upgraded, select an alternate boot disk that is at least the same size as the root partition of the primary boot disk. If you are upgrading an SFHA environment, this step is performed on each node in the cluster.
If the primary boot disk is mirrored, you need to break off the mirror for the alternate boot disk.
Before you perform the Live Upgrade, take offline any services that involve non-root file systems. This prevents file sytems from being copied to the alternate boot environment that could potentially cause a root file system to run out of space.
Patch the operating system for Live Upgrade. Visit the following site for information on the required patches.

The version of the Live Upgrade packages must match the version of the operating system to which you want to upgrade on the alternate boot disk. If you are upgrading the Solaris operating system, do the following steps:
Remove the installed Live Upgrade packages for the current operating system version:
All Solaris versions: SUNWluu, SUNWlur packages.
Solaris 10 update 5 or later also requires: SUNWlucfg package.
Solaris 10 zones or Branded zones also requires: SUNWluzone package.
From the new Solaris installation image, install the new versions of the Live Upgrade packages:
All Solaris versions: SUNWluu, SUNWlur packages.
Solaris 10 update 5 or later also requires: SUNWlucfg package.
Solaris 10 zones or Branded zones also requires: SUNWluzone package.
Symantec provides the vxlustart script that runs a series of commands to create the alternate boot disk for the upgrade.
To preview the commands, specify the vxlustart script with the -V option.
Symantec recommends that you preview the commands to ensure there are no problems before beginning the Live Upgrade process.
The vxlustart script is located on the distribution media, in the scripts directory.
# cd /cdrom/scripts
# ./vxlustart -V -u targetos_version -s osimage_path -d diskname
For example, to preview the commands to upgrade only the Veritas product:
# ./vxlustart -V -u 5.10 -U -d disk_name
For example, to preview the commands for an upgrade to Solaris 10 update 6:
# ./vxlustart -V -u 5.10 -s /mnt/Solaris_10u6 -d c0t1d0
If the specified image is missing patches that are installed on the primary boot disk, note the patch numbers. To ensure that the alternate boot disk is the same as the primary boot disk, you need to install any missing patches on the alternate boot disk.
In the procedure examples, the primary or current boot environment resides on Disk0 (c0t0d0) and the alternate or inactive boot environment resides on Disk1 (c0t1d0).
