Installing Solaris from remote CD

Hi

I have a Solaris 2.5 machine with no CD Drive and want to upgrade/reinstall 2.8. the only machine I can use for this is on a different network (boxes can see each other though). I have gone thru the steps as per the article "Appendix C Installaing or Upgrading from a remote dvd-rom and cd-rom" and have carried out the add_install_client which creates files in /tftpboot directory.

When I shutdown the 2.5 box and issue the command boot net I get errors like
Lost carrier (transceiver cable problem?)
cable problem or twisted pair hub link-tets disabled
Timeout waiting for arp/rarp packets.

My question is

1. Can you do this remote install across networks

If so then
2. What am I doing wrong?

Regards

Chris

"Lost carrier (transceiver cable problem?)

Those error message result from the box not seeing a working Ethernet connection when booting up. Its informational and can be ignored - unless you DO have a supposedly-working Ethernet connection for the box and its not seeing it, which could be Very Bad (tm).

"Timeout waiting for arp/rarp packets."

This happens because the box is configured to boot to the network, and it doesn't have a valid network connection. Again, something you can ignore unless it is supposed to be booting to the network instead of local disk.

1) Yes, you can. You obviously need a working Ethernet connection, and you need to have a Solaris Jumpstart server on the network from which the server can download and install the OS.

2) I dunno.

In answer to your questions.

I DO have a working Ethenet connection (tpe) which works fine when the 2,5 box is booted.

From the ok prompt, I AM trying to boot off the network. The 2.5 box does not have a CD drive and therefore I am trying to use the one on the other box. I do't particularily want to set up a Jumpstart server - just use the CD drive to enable me to install 2.8 on the 2.5 box.

Ah. Interesting. What is this hardware you're working with? Solaris on Sparc or Intel?

Sparc what? SparcServer 20? Ultra 1? E220?

OBP version?

I don't think you can do this across subnets;  You need a boot helper system on the "local" subnet

By this, do you mean that the machine that is sharing the Cd drive MUST be on the same subnet or is a "boot helper system" some kind of "middleman" acting as a "gateway"?

tfewsterCommented:
I'll see if I have any notes at work, but if I recall correctly, network boot will only boot from a bootp server on the same subnet;  Once that initial boot is done, the full tcp/ip stack is loaded so that the "client" you're building can route to other subnets and see the CD drive on the "server".

As mentioned in the above comments, "boot net" need to have a boot (or Jumpstart)
server sitting in the SAME subnet.

You can connect your box to the same subnet as your other Sun box with a CDROM
 (use a temporary IP and hostname) to perform a fresh install, and then then run:

sys-unconfig

to unconfig the box, move it back to your target network and then boot it up and
reconfig the Sun box.

Or
If you have a Linux box (or a Linux lap top) in the same subnet,  set it up as
as Jumpstart server, and then install your Sun box.

Have a look at the following page to learn how to setup Linux as a Jumpstart server:

http://www.transposed.org/techstuff/linux-jumpstart.html
http://www.unixpeople.com/HOWTO/jumpstart_on_linux.html

PS: if you have a Linux laptop with a large HD, it will become very handle when you have
      to install a lot of Sun boxes (or Solaris x86 PC) in different subnet.

Thanks to all who responded
I have now put in a request to get the boxes put on the same subnet for the installation. I will then follow yuzh's instructions.
