Setting up the iSCSI protocol on a host and storage system

The procedure for setting up the iSCSI protocol on a host and storage system follows the same basic sequence for all host types.

About this task

You must alternate between setting up the host and the storage system in the order shown below.

Steps

  1. Install the initiator HBA and driver or software initiator on the host and record or change the host’s iSCSI node name.

    It is recommended that you use the host name as part of the initiator node name to make it easier to associate the node name with the host.

  2. Configure the storage system, including the following:
    • Licensing and starting the iSCSI service
    • Optionally configuring CHAP
    • Creating LUNs, creating an igroup that contains the host’s iSCSI node name, and mapping the LUNs to that igroup
    Note: If you are using SnapDrive, do not manually configure LUNs. You must configure them using SnapDrive after it is installed.
  3. Configure the initiator on the host, including the following:
    • Setting initiator parameters, including the IP address of the target on the storage system
    • Optionally configuring CHAP
    • Starting the iSCSI service
  4. Access the LUNs from the host, including the following:
    • Creating file systems on the LUNs and mounting them, or configuring the LUNs as raw devices
    • Creating persistent mappings of LUNs to file systems
