Transferring control to the slave system
If the master system fails you need to use the following procedure to transfer control of the
RTAs to the slave system
1. On the slave system, edit the rio.cf file (located in the /etc/rio/ directory), and alter the
host card setting from "noboot" to "boot". (for example, "HOST:a5000387:HOST 1:boot:").

Appendix B rio.cf administration file .
2. On the slave system, run the rioconfig utility. See Updating your RIO system
configuration on page 51 .
3. on slave system command line type /etc/rioreboot -n and press the Enter key
All RTAs and ports will be reset (this may take some time), and when complete will be
accessible from the slave system.
