LPIC-2 Practice Question: Block Devices, Filesystems and Advanced Storage
A system administrator notices that a new iSCSI target is not appearing as a block device after running iscsiadm. The target is known to be online and reachable. What is the most likely cause?
⚠ Common exam trap
Candidates often assume the issue is a configuration error (like a wrong IQN or missing initiator name) when the problem is actually a missing or stopped service, because they overlook the dependency of `iscsiadm` on the `iscsid` daemon.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The iSCSI service (iscsid) is not running.
The iSCSI initiator requires the `iscsid` daemon to be running in order to process discovery and login requests from `iscsiadm`. Even if the target is online and reachable, without the `iscsid` service, the kernel's iSCSI layer cannot establish a session or create the corresponding block device (e.g., /dev/sdX). This is the most likely cause because the administrator has confirmed network connectivity and target availability, leaving the service state as the primary suspect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The iSCSI initiator name is not set.
Why it's wrong here
Initiator name is required but usually set; missing it would prevent login, but the question states the target is reachable, so iscsid is more likely.
- ✗
The target IQN is not specified correctly.
Why it's wrong here
Incorrect IQN would fail, but the administrator likely specified it correctly.
- ✓
The iSCSI service (iscsid) is not running.
Why this is correct
The iscsid daemon must be active to manage sessions.
- ✗
The network interface is down.
Why it's wrong here
The target is reachable, so network is fine.
