Common Network Booting Errors

Insufficient Response to PXE Boot Request

PXE-E16: Valid PXE offer not received

When the above error is seen during a PXE boot, one of the following may be true (this is not an exhaustive list) :

File Size Miscalculated

PXE-E05: Download buffer is smaller than requested file.

This problem is related to firmware in EFI on the HP Integrity rx1600/rx1620 systems. Upgrade the firmware on the system to a version that addresses the above message (system firmware 02.11 or later.)

When using a tftp server that does not support the tsize option, a file must be completely downloaded to determine its size. The file is then downloaded again into memory allocated based on the determined size. The EFI code calculates the wrong size, hence the allocated buffer is too small to hold the file.

Apart from updating the firmware, using a tftp server that supports the tsize option will also solve this problem. The tsize option allows a tftp client to ask the tftp server for the size of the file. This saves the client from having to download the file to determine its size.

The HP-UX 11i v2 operating system supports the tsize option from first release; HP-UX 11i v1 requires the patch PHNE_32825.

Using a tftp server that supports the tsizeoption makes network booting faster, since every file to be downloaded from the Ignite server via tftp does not have to be downloaded twice (once to determine its size, and again to download it into memory.)

File Size Miscalculated on HP Integrity Virtual Machines

AUTOBOOTING...Obtaining size of Rel_B.11.23/IINSTALL (63450640 bytes)

Downloading file Rel_B.11.23/IINSTALL /

TFTP session failed. (reason:Buffer Too Small)

Could not open Rel_B.11.23/IINSTALL

The error TFTP session failed. (reason:Buffer Too Small) is applicable only to HP Integrity Virtual Machines. The reason is the same as described under the heading: File Size Miscalculated. No version of HP Integrity VM contains fixed firmware at this time. To resolve this issue, install the patches listed in the File Size Miscalculated section so the tftpd daemon supports the tsize option.
