Since you don't have the SUNWdetached.xml, you can't use it. Assuming you have a backup of the system, you could restore a copy of /etc/zones/ to /etc/zones/restored-.xml, then run: zonecfg -z create -t restored- If that's not an option or is just too inconvenient, use zonecfg to configure the zone just like you did initially. That is, do not use "create -a", use "create", "create -b", or "create -t " followed by whatever property settings and added resources are appropriate. After you get past zonecfg, you should be able to: zoneadm -z attach If the package and patch levels don't match up (the global zone perhaps was installed from a newer update or has newer patches): zoneadm -z attach -U or zoneadm -z attach -u Since you seem to be doing this in a test environment to prepare for bad things to happen, I'd suggest that you make it a standard practice when you are done configuring a zone to do: zonecfg -z export > /zonecfg.export Then if you need to recover the zone using only the things that are on the SAN, you can do: zpool import ... zonecfg -z -f /zonecfg.export zoneadm -z attach [-u|-U] Any follow-ups should probably go to Oracle Support or zones-discuss. Your problems are not related to zfs. -- Mike Gerdts http://mgerdts.blogspot.com/ ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Wouldn't it be the same as just copying (or moving) a zone root
without first detaching it ? I have successfully attached zones in
that state (shut down but not detached).
In answer to an earlier post, I'm not sure what checks have been
added to zonecfg and zoneadm to prevent accidentally over writing a
zone. But first you need to make sure that you can see the zoneroot
and it's data. You may have to force an operation since you did not
detach the zone.

I missed that you're using s10 *without* Live Upgrade. If so, I don't know what the resulting zone behavior would be.

Re: [zfs-discuss] Non-Global zone recovery
It looks like it is looking for SUNWdetached.xml which will create when we deattch the zone but in my case, I didn't deattach the zone before reimage.

Hi Ram, Which Solaris release is this and how was the OS re-imaged? If this is a recent Solaris 10 release and you used Live Upgrade, then the answer is yes. I'm not so sure about zone behavior in the Oracle Solaris 11 Express release. You should just be able to import testpool and boot your zones.

If the NG Zone is on a different zpool, and that zpool was not
over-written, then you can easily recover the NG Zone, but that is
more a question for the zones-discuss list :-) Once you can see the NG
Zone again (zpool import, probably with a -F), then you just recreate
the NG Zone using zonecfg but do NOT install it. Once it is created
you just attach it with zoneadm (and use the upgrade on attach option,
I forget the flag if the OS rev of the Global zone is now newer).

You are probably OK. What was the old OS version and what is the new
OS version ?
