This page is abut a problem into Ubuntu server 18.04. Same problem, same preparation that cause the problem and in different Ubuntu 18.04 and.

All happen when working to chapter of Building a VMware vSphere Virtual Lab with VMware Fusion – Part 5: Create a Ubuntu iSCSI Target and Configure Multipathing

Case 1. After Upgrading Ubuntu Server 16.04 to 18.04 LTS in 2020.04.11

Problem:

silvia@silvia:~$ sudo scstadmin -config /etc/scst.conf
Failed to obtain SCST version information. Are the SCST modules loaded?

I try restarting scst and running the config command again:

silvia@silvia:~$ sudo /etc/init.d/scst stop
[ ok ] Stopping scst (via systemctl): scst.service.
silvia@silvia:~$ sudo /etc/init.d/scst start
[ ok ] Starting scst (via systemctl): scst.service.
silvia@silvia:~$ sudo scstadmin -config /etc/scst.conf
Failed to obtain SCST version information. Are the SCST modules loaded?

What does dkms status show?

silvia@silvia:~$ dkms status
scst, 3.4.0, 4.15.0-96-generic, x86_64: installed

Case 2. After installing Linux (Ubuntu Server 18.04) on a Mac with VMware Fusion in 2020.04.13

At the and of chapter Building a VMware vSphere Virtual Lab with VMware Fusion – Part 5: Create a Ubuntu iSCSI Target and Configure Multipathing it is a problem. To solve the problem I apply again all from the chapter of Step 4.2. Installing SCST on Ubuntu 18.04.

The same problem appears at Step 4.6. Export the disk image as an iSCSI LUN:

silvia@silvia:~/scst-build/scst$ sudo scstadmin -config /etc/scst.conf
Failed to obtain SCST version information. Are the SCST modules loaded?

I don’t know a solution to solve this problem.
