Hi guys I have a Solaris 10 development box and I can't install Solaris
Studio 12.3 because of missing patches. Looks like the latest Solaris has
the necessary patches already so maybe the easy way is to install that on
this box. What is the best way to backup my /export/home and other locally
built directories and zones so I can try to get things back to normal after
installing a newer Solaris? Worst case I can just copy a few directory trees
over NFS but I don't know how to backup zones. It took a long time to set
this up and I don't want to go through that again if possible.
Thanks,
Bill

Installing patches isn't hard...

are you sure there are missing patches? IIRC solaris studio ships with
all the necessary OS patches, see
http://docs.oracle.com/cd/E24457_01/html/E21988/gimhj.html#scrolltoc
"Several operating system patches are required for the proper
operation of the compilers and tools in the Oracle Solaris Studio 12.3
release on the Solaris OS (see Appendix D, Patch Identification
Numbers and Descriptions). To install the required Solaris OS patches,
you can run the install_patches.sh utility that is included in the
product download."
PS: Instead of installing from scratch you could also use liveupgrade…

I was looking over the man page but I get the impression detach is supposed
to be used when you are actually moving the zone from one system to
another. I still don't get why you would have to do that but ok. In this
case it's only I need to backup the zone and then reinstall it on the same
box after installing a later Solaris. Is there any place to find a writeup
on what detach does and why it might be used?
Thanks,
Bill

Hi Stefan,
There are some but not all patches in the tarball. Specifically for whatever
reason they decided not to include a kernel patch I think the number is
144500 but don't quote me on it.
I have not tried liveupgrade and I'm not sure how to do it. If I can safely
backup the zones it's probably easier for me to reinstall and hopefully not
have to do that again.

The LU docs:
<URL:http://docs.oracle.com/cd/E26505_01/html/E28038/index.html>
lu may not be easy depending on whether
you have a ZFS root or if not, unused Solaris slices for the
new boot environment.
How is your system currently configured?
If you're going to reinstall, you may be better off moving
to Solaris 11.1 and migrating your existing zones to Solaris 10
brand zones.

Do you require the kernel patch?

Hi John,
That's the one. For whatever reason they decided not to include that patch
in the tarball and I can't install Solaris 11 on this box because it is not
supported. Everything is ZFS but it's an older Sparc box.
Thanks,
Bill

backup and then give liveupgrade to the latest Solaris 10 release
a try.

Hi John,
I got a message from the installer saying 144500 was needed so I don't
understand why you are saying it's not needed unless you are saying if I
liveupgrade I don't need it. Which was sort of my question from the
beginning, what's the best way for me to back my zones up so I can
reinstall.
I'm still confused about what the point of detach is and can't get much info
from the man page on that.
I would like to backup and install but I don't know the best way to do
that. I guess if I make a tarball of everything under / I will lose all my
ZFS filesystems if I had to restore from that. So maybe the question now
becomes how to backup a whole system so I can either liveupgrade it however
that works or selectively restore zones etc.
Thanks,
Bill

It prepares a zone to be attached to a new or upgraded system.

shutdown your zones, detach them, snapshot and send your filesystem snapshots
to your NFS server, live upgrade, boot your new BE, "attach -u" your zones and
boot your zones.

The Solaris Studio docs say the kernel patch is only needed

Thanks John. The warnings from the installer about missing patches seemed
ominous. I'll try backing the system up as you wrote.
