  • Hi,

    Encapsulating a disk

    Warning:

    Encapsulating a disk requires that the system be rebooted several times. Schedule performance of this procedure for a time when this does not inconvenience users.

    This section describes how to encapsulate a disk for use in VxVM. Encapsulation preserves any existing data on the disk when the disk is placed under VxVM control.

    To prevent the encapsulation from failing, make sure that the following conditions apply:

    • The disk has two free partitions for the public and private regions.

    • The disk has an s2 slice.

    • The disk has a small amount of free space (at least 1 megabyte at the beginning or end of the disk) that does not belong to any partition. If the disk being encapsulated is the root disk, and this does not have sufficient free space available, a similar sized portion of the swap partition is used instead.

  • Use "vxdisk list disk_name" to see private length and public length and also offset so you know if private region is at beginning or end of disk.

    This works for any disk, not just root disk
