rpcinfo(1m) can be used to locate boot servers in your subnet as well as to verify that the machine(s) you have set up as boot servers actually will respond to a boot request. Please note a response only means the service is registered. It does not mean that there actually is a bootable image that the client (machine attempting to boot) can use.

To check if a particular machine has the boot service registered type the following:

rpcinfo -s <hostname> | grep bootparam

Here is an example:

$ rpcinfo -s u140-hard | grep bootparam
program version(s) netid(s) service owner
100026 1 ticots,ticotsord,ticlts,tcp,udp bootparam superuser

To see what other machines are answering boot requests

rpcinfo -b 100026 1

Here is a sample output

129.148.190.179.128.48 radioactive
129.148.190.100.131.19 loadme-190
129.148.190.179.128.48 radioactive
129.148.190.100.131.19 loadme-190

NOTE: The rpcinfo(1M) manpage has lots more information

Internal Comments

This is very useful for Sun Enterprise[TM] 10000 netboot
problems. Often the bootserver that responds is NOT the ssp and the
bootimage that is found and is attempted to be used is not correct
for the E10K causing panics and/or boot hangs.

In addition, N/T boxes have been know to respond, and E10Ks
cannot boot from that image
