We built this script to bring up ipoib on RHELS 9.2. Your mileage may vary....
[root@xcat02 postscripts]# more ipoib

# Define the log function
function log {
echo "$(date +"%Y-%m-%d %H:%M:%S") - $1" >> /root/post.log 2>&1
logger -t xcat "$1"
}
# Log script start
log "Starting ib-config-as-eth script"
# Find the primary interface and its IPv4 address
log "Finding the primary interface and its IPv4 address"
primary_interface=$(ip route | awk '/default/ {print $5; exit}')
primary_ip=$(ip addr show dev $primary_interface | awk '$1 == "inet" {gsub(/\/.*
$/, "", $2); print $2}')
# Replace "172.20." with "172.25." in the primary IP address
log "Replacing IP address"
ib_ip=${primary_ip/172.20./172.25.}
ib_conname=ib0
# Find first ib interface name
ib_ifname=$(cd /sys/class/net; ls -d ib* | head -1)
[[ -n $ib_ifname ]] || exit
