Hi Enda,
The "cluster" BrandZ zone :
1. will use the same kernel.
2. will use the same libs/binaries
3. will use the same patch+packaging commands
4. will use the same upgrade commands
The "cluster" BrandZ zone uses the BrandZ callbacks to
add value. We actually use all of the existing BrandZ callbacks,
we just add a hook for this BrandZ zone type so that our
code gets called in addition to the basic zone functionality.
So it is appropriate to think of the "cluster" BrandZ zone
as another flavor of the "native" zone type.
Regards,
Ellard

Hi Ellard
Thanks for the info, very interesting, some questions
So Brandz zone types that use the patch+packaging commands will be
running some flavour of Solaris, but not necessarily the same kernel as
the global, or perhaps different libs/binaries as oppose to kernel.
If so how will they be patched?
ie will they have differenet package versions that those in global zone?
regards

Hi Enda,
This provides a good opportunity to clear up some misinformation.
The BrandZ "lx" zone type does not use standard patch/package
commands.
There will be BrandZ zone types that do use standard patch/package
commands. The Cluster group is developing now a "cluster" BrandZ
zone type that uses the BrandZ callbacks to enhance a zone.
The "cluster" BrandZ uses standard patch/package commands.
The Zones & BrandZ team in Solaris told us that a BrandZ approach
was the correct way to enhance a zone.
We are now in the middle of correcting these problems.
If you have information about places where this problem
appears, please let us know so that we can fix the problem.
Thanks,
Ellard

Hi,
On my machine (running s01u4_06) I have 3 local zones.
pship2 @ / $ zoneadm list -cv
ID NAME STATUS PATH
BRAND IP
0 global running /
native shared
2 cz2 running /zones/cz2
my_brand shared
5 cz4 running /zones/cz4
native shared
- cz3 installed /zones/cz3
lx shared
pship2 @ / $
cz2 is "my_brand" branded zone
pship2 @ / $ zoneadm -z cz2 mount
zoneadm: zone 'cz2': mount operation is invalid for branded zones.
Why is mount command disallowed for a branded zone ?
I can boot the zone, using the normal zoneadm -z cz2 boot command
Note: The config.xml and platform.xml for "my_brand" is identical to
the "native" brand except for the brand name.
Hi
mount is an internal state used by the patch/package commands only.
It basically does some mount magic, such that the zone's zone is
mounted in from the global lofs, plus /dev etc. Not really applicable
to a zone that is not native as it cannot be patched.
