Creating Boot Environment for Live Upgrade

Question

Hello.
I'd like to upgrade a Sun Fire 280R system running Solaris 8 to Solaris 10 U4. I'd like to use Live Upgrade to do this. As that's going to be my first LU of a system, I've got some questions. Before I start, I'd like to mention that I have read the �Solaris 10 8/07 Installation Guide: Solaris Live Upgrade and Upgrade Planning� ([820-0178|http://docs.sun.com/app/docs/doc/820-0178]) document. Nonetheless, I'd also appreciate pointers to a more �hands-on� documentation/howto reg. live upgrade.
The system that I'd like to upgrade has these filesystems:
(winds02)askwar$ df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/md/dsk/d30 4129290 684412 3403586 17% /
/dev/md/dsk/d32 3096423 1467161 1567334 49% /usr
/dev/md/dsk/d33 2053605 432258 1559739 22% /var
swap 7205072 16 7205056 1% /var/run
/dev/dsk/c3t1d0s6 132188872 61847107 69019877 48% /u04
/dev/md/dsk/d34 18145961 5429315 12535187 31% /opt
/dev/md/dsk/d35 4129290 77214 4010784 2% /export/home
It has 2 built in harddisks, which form those metadevices. You can find the �metastat� at http://askwar.pastebin.ca/697380. I'm now planning to break the mirrors for /, /usr, /var and /opt. To do so, I'd run
metadetach d33 d23
metaclear d23
d23 is/used to be c1t1d0s4. I'd do this for d30, d32 and d34 as well. Plan is, that I'd be able to use these newly freed slices on c1t1d0 for LU. I know that I'm in trouble when c1t0d0 now dies. But that's okay, as that system isn't being used anyway right now...
Or wait, I can use lucreate to do that as well, can't I? So, instead of manually detaching the mirror, I could do:
lucreate -n s8_2_s10 -m /:/dev/md/dsk/d30:preserve,ufs \
-m /usr:/dev/md/dsk/d32:preserve,ufs \
-m /var:/dev/md/dsk/d33:preserve,ufs \
-m /opt:/dev/md/dsk/d34:preserve,ufs
Does that sound right? I'd assume, that I'd then have a new boot environment called �s8_2_s10�, which uses the contents of the old metadevices. Or would the correct command rather be:
lucreate -n s8_2_s10_v2 \
-m /:/dev/md/dsk/d0:mirror,ufs \
-m /:/dev/md/dsk/d20:detach,attach,preserve \
-m /usr:/dev/md/dsk/d2:mirror,ufs \
-m /usr:/dev/md/dsk/d22:detach,attach,preserve \
-m /var:/dev/md/dsk/d3:mirror,ufs \
-m /var:/dev/md/dsk/d23:detach,attach,preserve \
-m /opt:/dev/md/dsk/d4:mirror,ufs \
-m /opt:/dev/md/dsk/d24:detach,attach,preserve
What would be the correct way to create the new boot environment? As I said, I haven't done this before, so I'd really appreciate some help.
Thanks a lot,
Alexander Skwar

I replied to this thread: Re: lucreate and non-global zones as to not duplicate content, but for some reason it was locked. So I'll post here...The thread was locked because you were not replying to it.
You were hijacking that other person's discussion from 2012 to ask your own new post.
You have now properly asked your question and people can pay attention to you and not confuse you with that other person.
