Force unmount of a SWAP filesystem left over from bad Live Upgrade
Hello,
Long story short, we built an alternate boot env. back in July and applied the latest CPU to about 15 servers. Of the 15 servers, 7 servers failed to start the zones after the luactivate / reboot. The zones failed to rename from <zone>-<boot_env> back to <zone>. This is fixed in patch 121430-95.
Anyway, we got that mess fixed up (or so we thought) but now I'm trying to apply the Oct CPU and running into an issue. I can build a new boot env. I can even apply-prereq but I cannot patch the BE.
It appears there is zone/lu mount that is causing me this problem.
We rebooted one of the servers and the lu mount did not come back and than we can complete the installcluster / installpatchset.
Is there any way for me to force an unmount of this zone lu SWAP?
I don't think I'll be able to request that we reboot 6 production servers just to patch them and reboot them again.
HELP!
EDIT: Two things I want to mention, no, the /etc/zones/index does not list the global zone as configured instead of install (at global or in BE) and no I am not missing zone packages. I know this is related to the zone lu SWAP.

On Solaris 10 local zone swap space is inherited from the global zone. So the swap you are trying to manipulate should show up there.
This swap space is obviously still in use so you probably need to tell the system to stop using it (provided the system has enough swap space elsewhere to keep running).
This is a Solaris 10 server with a ZFS root file system.
The swap is at the global zone. That is where I am seeing it. I checked the (single) zone running on the box and it doesn't appear to be using that swap volume.

I want to basically update an ABE that someone created a few months back.
I'm sure stuff has changed since it was made, and I was going to delete it and create a new one.
But from what I'm looking at, the lumake appears like it would be a faster approach.
