Example VxVM Disk Groups: the Good and the Bad
As shown above, no secondary (mirror) disks should be included in VxVM disk groups,
and groups must contain disks of the same vendor. These restrictions apply when using
any of the Extended Frozen Image Service methods; they do NOT apply if you are using
the vxvm frozen image method.
