Firstly thanks for getting back to me, those commands have corroborated some of the assumptions i have been making.

I think the SVM package is installed anyway (by default), at this stage I dont think it's important I just wanted to verify for the benifit of my documentation.

what i have is:

Legacy database domains (on a 15K) we are migrating to branded zones, on two M5000's.

Those systems currently use VxVM. When they've been migrated to zones they'll still need the VxVM (on the global zone) to run. The containers themselves will be built on ZFS SAN. The oracle data groups are all mounted on UFS filesystems, because we all know; branded zones cant mount ZFS.

Sun cluster 3.2 using HA containers will be installed to the global zones.

What i need to know is: if a container fails over to the other global zone, what do i need to manually share with both of those servers, from a VxVM point of view, to enable that container to come back up?

I understand that SC will move the container over to the other global zone. Though, it wont be able to boot back up and mount it's filesystems if that global zone doesnt know about the others VxVM configuration, regarding the failed over container. So what do i need to do to ensure that happens?

NAME
native - native branded zone DESCRIPTION
The native brand uses the branded zones framework described in brands(5) to run zones installed with the same software as is installed in the global zone. The system software must always be in sync with the global zone when using a native brand. SUB-COMMANDS The following native brand-specific subcommand options are supported in zoneadm(1M). attach [-u] [-b patchid]... For native zones, zoneadm checks package and patch levels on the machine to which the zone is to be attached. If the packages/patches that the zone depends on from the global zone are different (have different revision numbers) from the dependent packages/patches on the source machine, zoneadm reports these conflicts and does not perform the attach. If the destination system has only newer dependent packages/patches (higher revision numbers) than those on the source system, you can use the -u option to update the attached zone to match the -revision packages and patches that exist on the new system. With -u, as in the default behavior, zoneadm does not perform an attach if outdated packages/patches are found on the target system. For native zones, one or more -b options can be used to specify a patch ID for a patch installed in the zone. These patches will be backed out before the zone is attached or, if -u was also specified, updated. install [-a archive] | [-d path] [-p] [-s] [-u] [-v] [-b patchid]... The native brand installer supports installing the zone from either the software already installed on the system or from an image of an installed system running the same release. This can be a full flash archive (see flash_archive(4)) or a cpio(1) or pax(1) "xustar" ar- chive. The cpio archive be compressed with gzip or bzip2. The image can also be a level 0 ufsdump(1M), a path to the top-level of a system's root tree, or a pre-existing zone path. With no options the zone is installed using same software as is running the global zone. To install the zone from a system image either the -a or -d is required. Either the -u or -p option is also required in this case. -a archive The path to a flash_archive(4), cpio(1), or pax(1) "xustar" archive, or a level0 ufsdump(1M), of an installed system. cpio archives may be compressed using gzip or bzip2. -b patchid One or more -b options can be used to specify a patch ID for a patch installed in the system image. These patches will be backed out during the installation process. -d path The path to the root directory of an installed system. If path is a hyphen (-), the zonepath is presumed to be already populated with the system image. -p Preserve the system configuration after installing the zone. -s Install silently. -u Run sys-unconfig(1M) on the zone after installing it. -v Verbose output from the install process.
