I'm fairly new to Solaris and am just getting to grips with using LU (Live Upgrade) for OS patching purposes.
I have successfully created and patched a new BE (boot environment) using the lucreate/luactivate commands.
On activating the patched BE I received the following instructions:
On rebooting the server, everything comes back up fine and my OS is now fully patched. This is a test server I am working on and want to get recovery procedures documented before I apply this to my live servers. Therefore i tried rolling back to the previous BE (pre patched)
Following the instructions given when running the luactivate command, i booted into single user mode and first ran
This presented me with lots of failures saying
for all my mountpoints. Is this correct?
I ignored these errors as I've read in some other forums that this can be ignored (not sure how true this is..)
The next few steps were, it seems, completed successfully
The final step was to run
This resulted in an error of
Could anyone offer any assistance or see that I'm missing anything out please?
Any other output that is needed, please let me know.
Well, I raised a call with Oracle and received the following response:

Anyhow, from the brief description I believe you hit known bug
CR 6923286 "luactivate fails in single user mode during fallback activation"
Fixed Version s10u10_09
The fix is not in the latest publicly available LU patch.
If the issue is causing considerable ongoing impact and preventing you using live upgrade, then we could provide you with an IDR patch which contains a number of LU test fixes including a fix for 6923286 . This will require an escalation against the bug and the SR will probably need to remain open while installed so you can report back any side effects from the IDR patch.
IDR147198
A workaround would be to instead "boot -L" and select the good BE.
e.g.
ok> boot -L
I'll be trying the boot -L command tomorrow and let you know how i get on..

During the boot-up process *nix runs scripts linked into the runlevel directories rc#.d. What I'm wondering is, how do I control the environment that those scripts see?
