| + | ==== Adding an appropriate IP address ==== | ||
| + | |||
| + | Depending on the server's iscsi portal configuration, it might be necessary to add an appropriate IP address to the initiator's machine network interface (NIC). If this is required, here is how to do it, in this case temporarily adding the appropriate IP address to the eth0 interface ([[https://www.garron.me/en/linux/add-secondary-ip-linux.html|reference]]): | ||
| + | |||
| + | <Code:bash> | ||
| + | > sudo ip address add 10.1.1.55/24 dev eth0 | ||
| + | </Code> | ||
| + | |||
| + | Once done, the temporary IP address can be removed using: | ||
| + | |||
| + | <Code:bash> | ||
| + | > sudo ip address del 10.1.1.55/24 dev eth0 | ||
| + | </Code> | ||
