Make sure you are using the correct boot command (you must
use the "install" keyword for newer Workstation (Series 700) systems).
For older systems, you may need to enter the boot command two or
three times.
Check for error messages on the server, logged to
the file /var/adm/syslog/syslog.log.
Look for instl_bootd
messages.
Make sure that the /etc/instl_boottab
file contains at least one IP address that is valid for your network.
Make sure the server for the install kernel is on
the same subnet as the system you are trying to boot. (The install
server itself does not need to be on the same subnet).
If the file /var/adm/inetd.sec
exists and has a tftp
entry, make sure it allows access to the addresses listed in /etc/instl_bootab.
If your system has multiple lan cards, make sure
/dev/lan0 you
pick the one connected to the proper network.
Check to see that /var/adm/syslog/syslog.log
has an entry such as the following:
inetd[306]: instl_boots/udp: Unknown service |
If there is also an entry in your local /etc/services
for instl_boots,
check to see if your system is set up to use NIS. If so, it may
be that the version of /etc/services
supplied by your NIS server needs to have the entries for instl_boots
and instl_bootc
added.
