1 Install iscsi-initiator-utils
Install iscsi-initiator-utils package.
$ sudo dnf install -y iscsi-initiator-utils
Add SELinux configuration.

2 Connect to iSCSI target with iscsiadm
Connect to iSCSI target with iscsiadm.

3 Mount iSCSI target device on boot
Connect to iSCSI target.
$ sudo iscsiadm -m discovery -t st -p “${ISCSI_TARGET_PORTAL}”$ sudo iscsiadm -m node –targetname “${ISCSI_TARGET_NAME}” -p “${ISCSI_TARGET_PORTAL}” -l
Create filesystem on iSCSI target device with fdisk and mkfs.
$ ISCSI_TARGET_DEV=/dev/sda$ cat <<EOF | sudo fdisk ${ISCSI_TARGET_DEV}np1wEOF$ sudo mkfs.ext4 ${ISCSI_TARGET_DEV}1
Add mount entry to /etc/fstab. For avoiding mounting before network initialization, you need to add _netdev option. For making x-systemd.automount to mount, you need to add x-systemd.automount to option.
$ uuid=$(sudo blkid | grep “^${ISCSI_TARGET_DEV}1:” | sed -e ‘s/.* UUID=”([^”]*)”.*/1/g’)$ cat <<EOF | sudo tee -a /etc/fstabUUID=”${uuid}” /mnt ext4 _netdev,x-systemd.automount 0 0EOF
