Can't boot from one system and install from another
Question:
Env:
AIX 4.2
sysback 4.1.3.1
Problem:
Customers boots from one system and trys to install from
another and it fails with this error message.
There are not install images
I was able to reproduce the problem.
I used three systems:
The client is on this network: 9.19.145.164
The boot server is on this network: 9.19.129.186
The install server is on this network: 9.19.129.127
The client uses the same gateway to get to both the boot and
install server systems.
1. cat /etc/hosts This looks correct
127.0.0.1 loopback
9.19.129.186 bootserver
9.19.129.127 instserver
9.19.145.164 instclient
9.19.145.240 instgate
2. sbclient instserver echo
sbclient: Network is unreachable
Unable to connect to instserver
3. netstat -ir
Name Mtu Network Address
lo0 16896 \
lo0 16896 127 loopback
tr0 1492 \8.0.5a.89.3.8
tr0 1492 9.19.145 instclient
4. netstat -rn
Routing tables
Destination Gateway Flags Refs use Interface

5. route add instserver instgate
instgate host instserver: gateway instgate
6. netstat -rn

9.19.129.186 9.19.145.240
9.19.145 9.19.145.164
127 127.0.0.1
7. sbclient instserver echo
Works correctly
8. exit
I then was able to select either option 2 or option 3
and it showed the remote install devices

I think I've found the problem. If the install server is
different than the boot server and a gateway is defined,
it appears to get defined for reaching the boot server but not
the install server (as I believe you suspect).
I would like you to do one more test:
Define the boto client without changing the client.sbinfo file. In other
words, the default install server will be the same as the boot
server. Then, use the menus after booting to change the IP
address of the install server. Then try to get the install
options from the server.
I SUSPECT the same problem will occur. As I was looking through the code,
it appeared that, once the network adapter was configured, the install
server's gateway would never get defined even after changing either the
gateway and/or server IP address using the menus.
After doing the above test, you can grab the following files from system
"johnson" and put then on the boot server. After doing so, please remake
the bootimage for the client:
/usr/lpp/sysback/inst/sysinstall
/usr/lpp/sysback/inst/sysmakevg
/usr/lpp/sysback/inst/sysnet
/usr/lpp/sysback/netinst/boot/rc.boot
Then retry the test using both processes (i.e. modifying the client.sbinfo
file AND changing the server in the menus) to see if this resolves both
issues (assuming there are two issues).
Please let me know your results, and thanks in advance for your help!
PS. NOTE that the sysinstall and sysmakevg programs have been modified only
to change the SPACES back to TABS, and the rc.boot file contains the
fix for the gateway address for RSPC network boots also.

Your fix did the trick. It is now working correctly

Thanks for the help testing this!
This will be fixed with sysback.rte 4.1.3.2
