Removing ports from a system
You can remove groups of ports from a live system using the following procedure:
1. Determine the name and/or unique number of the RTA you wish to remove from the
system.
2. Power off and detach an RTA from the RIO network. See
3. At the command prompt, delete the RTA entry from the device driver by typing
riodelete <unique number|"name">
and pressing the
Enter
key.
4. Using a suitable text editor, edit the
/etc/rio/rio.cf
file to remove the RTA you have just
powered off. Remove the RTA line that contains the unique number and/or name of the
RTA just deleted.
5. At the command prompt, syntax check the new configuration file and fix any errors by
typing
rioboot -s -c /etc/rio/rio.cf
and pressing the
Enter
key.
6. At the command prompt, upload the changes to the driver by typing
rioboot -u
and
pressing the
Enter
key.
7. At the command prompt, delete the device nodes from the
/dev
directory by typing
riomkdev -d <unique number|"name">
and pressing the
Enter
key.
Hint
You can do this disconnecting the RTA link and getting its name from the console
messages that occur when an RTA is disconnected from the network. Alternatively, use the
rioidentify
command to determine which RTA/name needs to be removed.
