Live Upgrade

My experience with live upgrade....

First, my system.

X86 laptop.  One hard drive.  Initial install.

c0d0s0 - /  (15G)
c0d0s1 - swap  (2G)
c0d0s3 - /extra  (15G and not mounted - set aside during initial install for the live upgrade copy of /)
c0d0s7 - zfs filesystem and given the rest of the disk space.

Two zones - stemplate & dir6.  Both are sparse zones.  This caused problems?  I had this in my output from Step Two orginally

WARNING: The file </tmp/lucopy.errors.4697> contains a list of <3>
potential problems (issues) that were encountered while populating boot
environment <b80>.
INFORMATION: You must review the issues listed in
</tmp/lucopy.errors.4697> and determine if any must be resolved. In
general, you can ignore warnings about files that were skipped because
they did not exist or could not be opened. You cannot ignore errors such
as directories or files that could not be created, or file systems running
out of disk space. You must manually resolve any such problems before you
activate boot environment <b80>.

That file said....

cpio: Error during chown() of "/.alt.tmp.b-clb.mnt/dev/zcons/stemplate/masterconsole", errno 22, Invalid argument
cpio: Error during chown() of "/.alt.tmp.b-clb.mnt/dev/zcons/dir62/masterconsole", errno 22, Invalid argument
cpio: Error during chown() of "/.alt.tmp.b-clb.mnt/dev/zcons/dir62/zoneconsole", errno 22, Invalid argument

I'm willing to wager that it is fixable.  However, these zones weren't that important at this time.  So, to walk through the live upgrade, I uninstalled and deleted these zones.
 

Currently, / has Open Solaris, b78.  The plan is to live upgrade to b80 onto c0d0s3.

Step One.  lustatus reports that no live upgrade environment has been established.
Step Two.  The initial live upgrade environment

 Now for the upgrade...  I have it in 6 cd iso images.  A little easier with one dvd image.  However, I learned a little more about live upgrade in doing it this way :)

 First, mounting an iso image...
# lofiadm -a /<path_to_iso>/solaris_1.iso /dev/lofi/1
# mount -f hsfs /dev/lofi/1 /mnt
# luupgrade -u -n b80 /mnt
# umount /mnt
# lofiadm -d /dev/lofi/1
 

Now, if this was a dvd image, you could skip over the rest of the cd images to install, however....

# lofiadm -a /<path_to_iso>/solaris_2.iso /dev/lofi/1
# mount -f hsfs /dev/lofi/1 /mnt
# luupgrade -i -n b80 /mnt    (selecting the typical install is just fine!)
# umount /mnt
# lofiadm -d /dev/lofi/1
 

Do like wise for images 3,4,5 & 6.

Okay, onto finishing up and booting into build 80.

Activate the new image -
# luactivate b80

Reboot, but with init 6!
# init 6

Inspect your work -

#  lustatus  

Boot Environment	Is	Active	Active	Can	Copy

c0d0s0	yes	no	no	yes	-
b80	yes	yes	yes	no	-
