Create a USB key on SmartOS

This page shows you how to create a new USB key on SmartOS (including on your existing head node or compute node) from an image file that has been downloaded from MNX.

• Note: These commands must be run in the global zone as root.

• Identify the USB key device

  # /usbkey/scripts/mount-usb.sh
  # df -h | grep /mnt/usbkey | awk '{print $1}' | sed -e 's/p1/p0/' -e 's/dsk/rdsk/'
  /dev/rdsk/c3t0d0p0
  # umount /mnt/usbkey

• So the device name in this example will be /dev/rdsk/c3t0d0p0.

  • Note: Your device location may be different.

  • Note: Use p0 (for the whole disk) and not p1 (for the first partition).

• Uncompress and unarchive the key image using gzip(1) and tar(1).

  # tar xvf usb-*.tgz usb-*img
  x usb-release-20110901-20110922T212927Z-179-4gb.img, 4000000000 bytes, 7812500 tape blocks

• Using dd(1M), copy the new image to key

  # dd if=usb-*.img of=/dev/rdsk/c3t0d0p0 bs=4096b

  • Note: All data on the USB key will be replaced.
• This process will take between 5 and 20 minutes.
• Your USB key now contains the Triton boot image.
