Troubleshoot an iSCSI Issue

About this Hands-on Lab

The Internet Small Computer Systems Interface (iSCSI) is standard for linking data storage. We can manage iSCSI either through the `targetcli` on the “target” (i.e., storage server) or the `iscsiadm` command on any initiators (i.e., connecting servers). In this hands-on lab, we’ll test our ability to troubleshoot a connection issue between the target and initiator.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Confirm iSCSI Setup and Replicate Issue

Review the iSCSI configuration and ensure the target is working. Additionally, replicate the issue on the initiator.

Resolve Issue

Update the appropriate iSCSI configuration file so the initiator setup matches the target.

Connect to the Target

Confirm the fix by connecting to iSCSI from the initiator.

Additional Resources

We have an app server that leverages an iSCSI backend for external data storage; however, when attempting to access the target from the initiator, the login hangs and ultimately errors. Replicate the issue, then resolve.
