Re: [xcat-user] Redhat/Rocky support

[David D J. <dav...@br...>]

We built this script to bring up ipoib on RHELS 9.2.  Your mileage may vary....

[root@xcat02 postscripts]# more ipoib 
#!/bin/bash

# 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

# Add InfiniBand connection
log "Adding InfiniBand connection $ib_ifname"
nmcli connection add type infiniband con-name $ib_conname ifname $ib_ifname tran
sport-mode Datagram

# Set IPv4 address
log "Setting IPv4 address to $ib_ip/16"
nmcli connection modify $ib_conname ipv4.addresses "$ib_ip/16"

# Set IPv4 method to manual
log "Setting IPv4 method to manual"
nmcli connection modify $ib_conname ipv4.method manual

# Ignore IPv6
log "Ignoring IPv6"
nmcli connection modify $ib_conname ipv6.method ignore

# Activate the connection
log "Activating the connection"
nmcli connection up $ib_conname

# Log script end
log "/postscripts/ipoib script completed"
