This error indicates that you have attempted to attach two SAN devices using the same drive number.

Things to try:

  * If you are using multiple ''[[:cmd:sanboot]]'' or ''[[:cmd:sanhook]]'' commands, check that you are using the ''%%--drive%%'' option to give a unique drive number for each SAN device.

  * If you have configured both a ''[[:cfg:filename]]'' and a ''[[:cfg:root-path]]'' via DHCP, note that iPXE will automatically attach the ''[[:cfg:root-path]]'' as a SAN device (using the default drive number) before downloading and booting the ''[[:cfg:filename]]''.
