Use the following sysfs path to check if the IP address has been applied:
/sys/class/iscsi_host/host<Number>/ipaddress
Table 2-2 shows the various configurations one can have, as well as the
iscisadm commands or yast tool to use to check iSCSI sessions.
NOTE
For target discovery and login to work, the adapter’s IP address must be
configured using either BIOS settings or iscsiadm. The following examples
show the iscsiadm commands to use to set the IP address.
