| Issue |
We are trying to change the logical node number for our machine. Where does the $NODE environment variable get defined and how can we change it?
|
| Solution |
The Process Manager (Proc32) defines the $NODE environment variable. It is set using the -l<node> option at boot time and is read only.
To change a machines node number($NODE), modify the boot image by changing the argument passed with the -l option to Proc, rebuild using buildqnx, and re-boot.
sys/Proc32
$ Proc32 -l $(lnode)
More than likey, if the node number of a machine is being changed, netowkring will be a concern, so be sure to update the /etc/config/netmap file.
