Copy a System Dump after Booting from Maintenance Mode

While copying a system dump on a non-dataless or non-diskless machine, if you reboot the machine in maintenance mode, you must perform the following steps.

Note: Use this procedure only if you cannot boot your machine in Normal mode.
  1. After booting from Maintenance mode, copy a system dump or tape using the following snap command:
    /usr/sbin/snap -gfkD -o /dev/rmt#
  2. To copy the dump back from the external media (such as a tape drive), use the tar command. Enter the following to copy the dump from the /dev/rmt0 tape:
    tar -x

    To copy the dump from any other media, enter:

    tar -xftapedevice
