We use cluster software, VCS, to mount and umount vxfs file systems into local zones the same way we mount and umount vxfs file systems in global zones. We simply specify the mount point as a directory inside the local zone.

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?

vxinstall

vxinstall(1M)															     vxinstall(1M)

NAME

       vxinstall - menu-driven Veritas Volume Manager initial configuration procedure

SYNOPSIS

       vxinstall

DESCRIPTION

       The  vxinstall utility provides a menu driven interface to configure Veritas Volume Manager (VxVM).  If you install the Veritas Volume Man-
       ager software package using the operating system's package administration commands, you can run vxinstall to configure VxVM for initial use
       on your system.

       Note: If you use the Veritas software installation scripts, do not run this utility.

OPERATIONS

       Licensing
	    vxinstall  first asks if you want to view the Veritas licenses already installed on the system.  Answering "yes" is equivalent to exe-
	    cuting the vxlicrep command (see vxlicrep(1)).

	    You are then asked if you want to add licenses for other Veritas products.	Answering "yes" is equivalent  to  running  the  vxlicinst
	    command (see vxlicinst(1)).  and entering a license key.

       Enclosure-Based Naming
	    You  can choose whether you want to use disk access names that are based on the device names assigned by the operating system, or that
	    are based on names that you assign to enclosures.

       System-Wide Default Disk Group
	    You can enter the name for the default disk group (defaultdg).  This is an alias for the disk group name that should be assumed if the
	    -g	option is not specified to a command, or if the VXVM_DEFAULTDG environment variable is undefined.  By default, defaultdg is set to
	    nodg (that is, no disk group).

NOTES

       From release 4.0 of VxVM, it is no longer necessary to run vxinstall to configure the rootdg disk group.  Disks	and  disk  groups  may	be
       added  to  VxVM	by  running  commands such as vxdiskadm(1M) or by using the graphical user interface without first running vxinstall.  The
       operation of VxVM does not require any disk groups to have been configured, and a disk group named rootdg does not need to  be  present	on
       the system.  Any disk group may be configured as the default disk group that is to be used with VxVM commands.  Any disk group named rootdg
       has no special significance to VxVM. See the vxdg(1M) manual page for further details.
