This varies per operating system. Regardless of the operating system, you must always keep bootp/DHCP services configured accordingly. In other words, you may have to modify the bootp/DHCP server to serve new units their IP addresses or to remove IP service for units no longer on the network.

• NT:

  There is an EtherLite configuration utility in our program group, which is used to both add as well as remove EtherLites. Note that each time you change the configuration, you will need to reboot. Also note that DHCP may need to be modified if IP addresses are added or changed to match the new configuration.

  It is not possible to change EtherLite configuration or add units without rebooting.

   

• Solaris 2.x:

  If all you have to do is add another unit, you may do this by simply running "/usr/local/STS/Install" (or Install.ether) to modify our configuration files.

  If you need to change the IP address of one or more units, or remove one or more units, you must hand edit /kernel/drv/ct.conf. Note that the syntax in this file is critical, so be very careful to copy an existing entry and simply carefully change the information as needed. It will be obvious what to do. The entry in ct.conf is quite simple, such as: els0="EM-16,192.9.200.221";

  Finally, do a reconfiguration reboot to pick up the changes.

  There is no way to add a unit without rebooting, but you can change the IP address of an existing unit by simply editing the ct.conf file (per above) and then killing and restarting cdetherd for that unit.

   

• HP-UX:

  If all you have to do is add another unit, you may do this by simply running "/usr/local/STS/Install" (or Install.ether) to modify our configuration files.

  If you need to change the IP address of one or more units, or remove one or more units, you must hand edit /etc/els.conf. Be very careful to copy and modify an existing entry, as maintaining proper syntax is very important in this file.

  Finally, after rebooting the system, simply run "/usr/local/bin/cdmknods -auto -replace" to synchronize the device files with the units known to the system.

  It is possible to add a unit without rebooting by running the Install script per above, but then kill any copies of "cdetherd" (as reported by the ps command) and then re-running the cdetherd startup script ("/sbin/cdetherd start"). Finally, you will also need to make the new nodes with "/usr/local/bin/cdmknods -auto -replace". At that point, you should be able to access the new ports. Please make sure to idle ALL EtherLite ports before doing this, as ALL EtherLites will go "offline" as a result of killing all copies of cdetherd.

   

• AIX 4:

  You must use SMIT to add and remove units as needed. If you want to change the IP address of a unit, you must simply remove it and then add it back in again using the new IP address. There is no direct way to change an IP address on a unit due to the nature of the information stored in the ODM database. Once a unit is removed, its associated device files are also removed. If you are adding a unit, you must create the device files for the unit using the tty menu in SMIT.

   

• SCO:

  You must simply run /usr/bin/cdelscfg to make the necessary changes and then reboot.

  It is not possible to change EtherLite configuration or add units without rebooting.

   

• Digital UNIX:

  If all you have to do is add another unit, you may do this by simply running "/usr/local/STS/Install" (or Install.ether) to modify our configuration files.

  If you need to change the IP address of one or more units, or remove one or more units, you must hand edit /etc/els.conf. Be very careful to copy and modify an existing entry, as maintaining proper syntax is very important in this file.

  Finally, run "/usr/bin/cdconfig -e > /dev/null" and reboot.
