Running alt_disk_install, alt_disk_copy and related commands on the OS device when DMP native support is enabled

When DMP is enabled for native OS devices, you can use the following procedures to run the alt_disk_install command, alt_disk_copy command, or related commands on the operating system device.

Running alt_disk_install in the physical environment

  1. Find the DMP device corresponding to the OS device path on which you plan to run the alt_disk_install command.
    # vxdmpadm getdmpnode nodename=hdisk13
NAME       STATE    ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME
==========================================================
emc0_0039  ENABLED  EMC        4     4    0    emc0
  2. Close references to the associated subpaths. Run the following command on the DMP device:
    # vxdisk rm emc0_0039
  3. Run the alt_disk_install command on the OS device.

    Refer to the OS vendor documentation for the alt_disk_install command.

Running alt_disk_install in the VIOS environment

  1. Find the DMP device corresponding to the OS device path on which you plan to run the alt_disk_install command.
    # vxdmpadm getdmpnode nodename=hdisk13
NAME       STATE    ENCLR-TYPE PATHS ENBL DSBL ENCLR-NAME
==========================================================
emc0_0039  ENABLED  EMC        4     4    0    emc0
  2. If the DMP device is exported to a VIO client, remove the mapping of the DMP device. From the VIOS, run the following command:
    # /usr/ios/cli/ioscli rmvdev -vtd VTD_devicename
  3. Close references to the associated subpaths. Run the following command on the DMP device:
    # vxdisk rm emc0_0039
  4. Run the alt_disk_install command on the OS device.

    Refer to the OS vendor documentation for the alt_disk_install command.
