Tftp error 8: TFTP option rejected

[George R. White]

I am trying to update the firmware level on a CPU for a Alphaserver 8200 running Tru64 Unix 5.1B. When I execute "P08>>>boot ewa0 -pro bootp" I get the follow error:

Trying BOOTP boot.
050415072227B0149SBroadcasting BOOTP Request...
.Received BOOTP Packet File Name is: /tftpboot/as8000_v20.exe

Tftp error 8: TFTP option rejected.?

bootstrap failure

Can someone help me resolve this problem?

Thanks

This error (8) is one of blocksize negotiation.

This alphaserver's firmware (AS8200) has a hardcoded blocksize of 512 bytes, whereas other alphaservers support later RFCs that allow for blocksize negotiation.

My suggestion is to check your TFTP server, and see if blocksize is settable.

Though this may not help you, in our production environment, we use RIS to serve our firmware images. This uses a MOP protocol (not BOOTP).
My assumption/hope is that other than blocksize, you have everything else pretty well worked out, and you don't need advice like "make sure you are serving the fw with the right server and using the right boot protocols".
