Become a Red Hat Certified Engineer (RHCE). Study objectives from the RHCE certification exam related to iSCSI storage networking.
- [Grant] Welcome to RHCE Cert Prep: Linux iSCSI Storage Area Networks. I'm Grant McWilliams, computer science instructor and Linux enthusiast. In this course we'll talk about creating iSCSI storage area networks using CentOS 7. We'll learn about exporting block devices via the iSCSI protocol and special terminology associated with iSCSI as well as persistent naming strategies. We'll install the target and initiator packages onto your virtual machines and configure the services. Next we'll walk through the process of creating a FILE IO backstore, target, LUN, and access control list in detail.
Then on the initiator we'll configure the access control list credentials, discover the targets, and log in. After we've logged in, we'll partition the exported drive and configure it for automatic mounting based on the UUID. After completing the step-by-step process, we'll walk through some real-world iSCSI scenarios such as creating a block device LUN, an LVM logical volume LUN, and then memory back to RAM disk LUN. We'll also learn how to remove iSCSI targets and backstores. I love Linux, and I'm excited to teach you about Linux iSCSI Storage Area Networks for the RHCE certification, so let's get started.
