Boot from SAN device


  sanboot [--drive <drive>] [--no-describe] [--keep] [<uri>]


Boot from an iSCSI target


Boot from an HTTP target


Boot from local drive 0x80

  sanboot --no-describe --drive 0x80

Attach a SAN target and then boot an installer held on another target

  sanhook --drive 0x81 ${root-path}
  sanboot --no-describe


Boot from the specified SAN drive. If no SAN drive is explicitly specified then the default SAN drive (0x80) will be used. If a SAN target URI is specified then it will be automatically attached as the specified SAN drive.

The SAN drive will be described via an appropriate mechanism (such as an iBFT for an iSCSI drive) unless the --no-describe option is specified.

Command status

Failure Booting was unsuccessful

It is generally impossible for this command to return successfully, since if the boot is successful then control will not return to iPXE.

The Master Boot Record (MBR) code present on most SAN targets will be unable to boot unless the target is attached as the default SAN drive (0x80).

If you wish to attach to multiple SAN targets, each target must be attached as a different SAN drive.

You can optionally specify a SAN target URI that will be automatically attached as the specified SAN drive before booting is attempted. This drive will be automatically detached if booting then fails, unless the --keep option is specified.

For the sake of backwards compatibility, you can use the keep-san setting to prevent iPXE from detaching a SAN drive, and you can use the skip-san-boot setting to prevent iPXE from booting from a SAN drive. The combination of both of these settings provides functionality which is approximately equivalent to the sanhook command.

You can use the sanboot command to boot from a local disk drive without exiting iPXE. This can be useful if BIOS bugs prevent you from being able to cleanly exit iPXE. For example:

  # Boot from local hard disk
  sanboot --no-describe --drive 0x80
