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.)

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.
