You shouldn't need to worry about NOTRAILERS unless you are needing to route packets. I assume that your NFS node containing the ufsdump that you want to restore is on the same subnet??

So let's go through this briefly. You are booted from a distribution install media DVD and are in single user with a # (root) prompt. You now want to connect to your NFS node so you need a working network interface. Let's assume that you need to reach 192.168.1.99 and you are going to set this node's ip address to 192.168.1.11 Of course, you are not compelled to use the actual production ip address of the system, only anything that will allow you to restore your dump file. Once the restore is done, upon reboot the ip address it will come up on will be whatever the system was set to that the dump was taken of. However, ENSURE that the ip address you use for the restore does NOT clash with another system. Assuming you are sure that the ip address you are configuring is unique there's no danger in connecting it to your switch upfront; in fact it's beneficial because you can see immediate results on screen.

So here we go.....(I usually follow some commands with '&&' to display the updated config if successful). Let's assume the interface in question is a bge0......

Code:

# ifconfig bge0 plumb
# ifconfig bge0 192.168.1.11 netmask 255.255.255.0
# ifconfig bge0 up && ifconfig bge0
# ping 192.168.1.99

(Note: I know you are asking about Solaris 9. This will work on Solaris 8,9 & 10. Solaris 11 has a different network configuration system.)

Once you can ping your NFS store system you can issue your mount command to get access to your dump file. See one of my previous posts on this thread.

When I need to do this myself whilst executing DR I simply type in the above 4 commands one after the other in quick succession and the interface is up. If that doesn't work for you then tell me what happens (error message please).

Hope that helps.

route.conf

ROUTE.CONF(5)						      BSD File Formats Manual						     ROUTE.CONF(5)

NAME

     route.conf -- static routes config file

DESCRIPTION

     The route.conf file is read by the staticroute rc.d script during system start-up and shutdown, and is intended for adding and removing
     static routes.

   FILE FORMAT
     Lines starting with a hash ('#') are comments and ignored.  Lines starting with a plus sign ('+') are run during start-up, while lines start-
     ing with a minus sign ('-') are run during system shutdown.  If a line starts with a '!', the rest of the line will get evaluated as a shell
     script fragment.  All other lines are passed to route(8).	During start-up, they are passed behind a ``route add -'' command and during shut-
     down behind a ``route delete -'' command.

FILES

     /etc/route.conf	 The route.conf file resides in /etc.

     /etc/rc.d/staticroute
			 rc.d(8) script that parses route.conf.

EXAMPLES

     In this example, the interface for the desired routing changes is set, the IP address on that interface is determined, and a route is added
     during startup, or deleted during system shutdown.

	   # Set interface and determine current IP address for added route.
	   !ifname=bnx0
	   !ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}')
	   net 10.10.1 -interface ${ipaddr}

     In this example, IP forwarding is turned on during start-up, and a static route added for 192.168.2.0.  During system shutdown, the route is
     removed and IP forwarding turned off.

	   # Turn on/off IP forwarding.
	   +sysctl -w net.inet.ip.forwarding=1
	   -sysctl -w net.inet.ip.forwarding=0
	   net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2
