What are the steps for setting up iSCSI in Linux?

The steps to set up iSCSI on a Linux system are as follows:

1. Install iSCSI Initiator: Use the following command to install the iSCSI Initiator package.

sudo apt-get install open-iscsi

1. Configure iSCSI Initiator: Edit the configuration file /etc/iscsi/initiatorname.iscsi to set the initiator name and the IP address of the iSCSI Target.
2. Connect to the iSCSI Target: Use the following command to connect to the iSCSI Target, replacing with the IP address of the iSCSI Target.

sudo iscsiadm -m discovery -t st -p <target IP>
sudo iscsiadm -m node --login

1. To view connected iSCSI Targets: use the following command to check the iSCSI Targets that are already connected.

sudo iscsiadm -m session -P 3

1. Format and mount an iSCSI device: Use the following command to view the newly connected disk device, and then format and mount it.

sudo fdisk -l
sudo mkfs.ext4 /dev/sdX
sudo mkdir /mnt/iscsi
sudo mount /dev/sdX /mnt/iscsi

1. The file that contains information about the file systems and how they should be mounted is known as the /etc/fstab file.

/dev/sdX   /mnt/iscsi   ext4   defaults   0   0

After completing the above steps, your Linux system will be able to successfully connect to the iSCSI Target and use the iSCSI storage device.
