Updating platform sun4v boot archive ts marriage dating

Halt and reboot commands will create big time bang, be aware!!!

Once system is up it should show new kernel patch version.

Great, it's been a week after patching and application, DB owners are happy with patching stuffs and now we need to perform post patching stuffs upon certain confirmations.

POST PATCHING WORK TO DO - A Week LATER....=========================================Now a week later I need to delete the old boot environment and rebuild the metadevices to be in mirror layout.

PCA setup tips can be found at - PCA needs in case setting it up - - PERL distribution- At least one server which is internet facing (this server will then act as a proxy to rest of servers)- Patch cross-reference file called (latest one always while patching)- Valid Oracle support (MOS) user ID and password- If at all required, some wrapper scripts to PCA To do so, let us mount the alternate BE on mount point say /a This will update patches on global as well as non-global zones.

Once the patches are installed it will automatically un-mounts the ABE sol10pu mounted on mount point /a.

There might be many more benefits out there, however I find above benefits best fit for my purpose.

So to summarize, all tasks except the reboot can be accomplished on an operational production system; the impact on any running process is minimal.

Live Upgrade is a combination of maximizing system availability when applying changes and minimizing risk by offering the ability to reboot to a known working state (your original environment). let's see how to do it in real life, in my current environment we have many servers which uses Solaris Volume Manager as their primary volume manager to manage the disk and data.

Now it's time to activate the ABE sol10pu which just been patched using Live Upgrade utility.

NOTE: Live upgrade always uses init 6 or shutdown commands.
