LiveUpgrade question

LiveUpgrade question

LiveUpgrade question

I need to understand how to upgrade a mirrored env using lu.
Current: Sol10 u3 sparc
Upgrade to: Sol10 u8

The current fs looks like this:

d10 mirrored md (root)
 d11 c2t0d0s0
 d12 c2t1d0s0

d20 mirrored md(swap)
 d21 c2t0d0s1
 d22 c2t1d0s1

d30 mirrored md(/var)
 d31 c2t0d0s3
 d32 c2t1d0s3

d40 mirrored md(/data)
 d41 c2t0d0s4
 d42 c2t1d0s4

d50 mirrored md(/export/home)
 d51 c2t0d0s5
 d52 c2t1d0s5

d60 mirrored md(metadb 250mb)
 d61 c2t0d0s6
 d62 c2t1d0s6

I want to break the mirror and upgrade the second subdisk.
Boot to the upgraded subdisks and if all is well resync it all back as it was.

This is what I have been trying, to no avail:
lucreate -c orig -n patchBE \
-m /:/dev/md/dsk/d12:ufs,mirror \
-m /:/dev/dsk/c2t1d0s0:detach,attach,preserve \
-m /var:/dev/md/dsk/d32:ufs,mirror \
-m /var:/dev/dsk/c2t1d0s3:detach,attach,preserve

ERROR: cannot create mirror <d12> with metadevice <d12>
ERROR: cannot create logical devices
ERROR: cannot configure and prepare file systems as they are current configured
ERROR: cannot perform requested file system operations

I figured that I cannot create the same metadevice so next I was going to try this...

lucreate -c orig -n patchBE \
-m /:/dev/md/dsk/d0:ufs,mirror \
-m /:/dev/dsk/c2t1d0s0:detach,attach,preserve \
-m /var:/dev/md/dsk/d1:ufs,mirror \
-m /var:/dev/dsk/c2t1d0s3:detach,attach,preserve

But even if that works how do I get back to my original configuration(including all the mirrored md's)?

Your help is appreciated!



RE: LiveUpgrade question

You should use:

If you have not broken the mirrors already for root and var in your original BE this will work. If you have already broke them then it will not.

lucreate -c orig -n patchBE -m /:/dev/md/dsk/d0:ufs,mirror -m /:/dev/md/dsk/d12:detach,attach,preserve  -m /var:/dev/md/dsk/d1:ufs,mirror -m /var:/dev/md/dsk/d32:detach,attach,preserve
