Using mksysb when the root volume group is under DMP control

You can create a mksysb image of the client. You can use the mksysb image to restore the root volume group, or to install on another client using NIM.

When the root volume group is under DMP control, use the following procedure to create the mksysb image.

To use mksysb when the root volume group is enabled for DMP

  1. Show the DMP node names.
    # vxdmpadm native list
    PATH              DMPNODENAME
    ===================================
    hdisk70           ams_wms0_491
    hdisk72           ams_wms0_491
    hdisk73  									ams_wms0_491
    hdisk74           ams_wms0_491
  2. Run the following command:
    # lspv | grep -w rootvg
    hdisk70  00c408c4dbd98818  rootvg  active
    hdisk72  00c408c4dbd98818  rootvg  active 
    hdisk73  00c408c4dbd98818  rootvg  active 
    hdisk74  00c408c4dbd98818  rootvg  active
  3. Remove the disk from DMP control.
    # vxdisk rm ams_wms0_491
  4. Create the mksysb image. Use Network Installation Management (NIM) to install the operating system on the client, using the new image.

    See the operating system documentation for detailed information about mksysb and NIM.

  5. Verify the status after reinstalling the operating system, using the following command:
    # vxdmpadm native list
    PATH              DMPNODENAME
    ===================================
    hdisk70           ams_wms0_491
    hdisk72           ams_wms0_491
    hdisk73  									ams_wms0_491
    hdisk74           ams_wms0_491
  6. Verify the configuration.
    # lspv | grep -w rootvg
    hdisk70  00c408c4dbd98818  rootvg  active
    hdisk72  00c408c4dbd98818  rootvg  active
    hdisk73  00c408c4dbd98818  rootvg  active
    hdisk74  00c408c4dbd98818  rootvg  active
    # lsvg -p rootvg
