While you are configuring this switch in your San, you need to set its IP address as per your local network requirements. In other cases, you may just want to change them as per the new requirements or if something happened that corrupted the IP address to make it unknown.

So, the three situations are :

If you know the IP address of your switch and it's a working configuration, all you need to do is to bring up your SanSurfer GUI ( /usr/opt/SUNWsmgr/bin/esm_smgr ), double click on the IP field of the switch that you want to work on, and then click on the network port icon in the picture of the switch that appears. This will take you to the 'Network Configuration' window that contains the fields for configuring the ethernet connection to this selected switch.

If you are setting the IP for the first time from the default switch IP of 10.0.0.1, then do following:

(a) Put the 'test mode switch' to the 5 o'clock position [ Note: 'test mode switch' is directly below the last port and is a small ten-position rotary switch that is only used for maintenance situations. The tiny notch on the switch indicates your position]

(b) Add the virtual IP address (10.0.0.x, netmask 255.0.0.0) to the existing Network card as follows:

# ifconfig hme0:1 plumb

# ifconfig hme0:1 10.0.0.2 netmask 255.0.0.0 up [make sure that 10.0.0.1 or 10.0.0.2 are not in use already in this network or use a crossover cable to connect the management station directly to the switch ethernet port. Put the ethernet cable back in place after you are done setting up the IP by this process]

# ifconfig -a [ To verify that above change has been made ]

(c) Perform the connect operation as follows and get the config file to your local machine:

# tftp <Return>

tftp> connect 10.0.0.1 <Return>

tftp> ascii <Return>

tftp> get config <Return>

tftp> quit <Return>

(d) Using vi editor, change the net address, netmask and gateway address in the config file to the desired settings.

(e) Perform the tftp connect again as in (c) above, and put the config file back on the switch.

(f) Turn the power switch OFF, and using a small screwdriver, rotate the 'test mode switch' counterclockwise to the Normal position (12 o'clock position), and now turn the power back ON to reset the switch chassis and have the new IP address take affect.

[Don't forget to replace the crossover cable with ethernet cable if used it as described in step (b)]

The other method is through RARP as described below: (throughout this process, the 'test mode switch' is in the 12 o'clock position)

(a) Include the ethernet address of your switch and the name that you want to give it in the /etc/ethers file of your local host.

(b) List the IP address that you want to assign to your switch and its name in the /etc/hosts file of the local host.

(c) Restart the rarpd daemon on the local host ( kill and restart /usr/sbin/in.rarpd -a ).

Note: As it looks, the rarp method is easier, but if it does not work, the tftp method should be tried instead.

comment : This is described in the internal SAN class, and makes sense.
Switches other than the Ancor switch of the Python config
may have a tip connection for this setting, as well.
