What data might that be? Something important > perhaps (the Priv sounds a bit spooky to me)? Yes. It's a bit complex to explain. When you 'initialize' a new disk, VxVM creates a private region and a public region. Your space is allocated out of the public region. Since it's a new disk, it can put them whereever it wants. However when you 'encapsulate' an existing disk, it doesn't have the same freedom. You might have already allocated space at the beginning and the end of the disk. So the public region has to encompass all that space. That usually means that it has to create a bit of space in the middle of the disk for the private region. Since this space is in the middle, it is both in the private region *and* the public region. To prevent that portion of the public region from being used, a subdisk is allocated that uses that spot, marking it as in use. If that subdisk were deleted, it's possible that something else would be allocated there. You can see that this is only needed on certain encapsulated disks. It shouldn't be seen on initialized disks. The old sun blueprint addresses this as well. You might want to look at it if you haven't before. It covers some of the details of what's happening in the encapsulated stuff. <http://www.sun.com/blueprints/0800/vxvmref.pdf> -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
