Scenario:
Use targetcli-fb to do mappings, using ibmvscsi target and client
driver.
Have both operational, then reboot the server, while leaving the
client on.
Problem: The client and server are both spamming ABORT messages, but it
will stop
immediately upon running "sudo targetcli". I know upon launching
targetcli, it reads
configfs, but does it do anything else that might fix the below ABORT
message spamming?
If anyone can help that would be great, thanks!
Hmm, this is a tricky one. I can't think of anything that running
targetcli should do that `targetctl restore` shouldn't have also done
on boot of the server (aka target).
Ohh, this is using TCMU? Is tcmu-runner running?
Yes, TCMU is running, its using TCMU with the file backed optical.

After further looking into this issue, it looks like TCMU is not up when
the target restarts...
sdn1@z2434ep2:~$ systemctl status tcmu-runner
● tcmu-runner.service - LIO Userspace-passthrough daemon
Loaded: loaded (/lib/systemd/system/tcmu-runner.service; static;
vendor preset: enab
Active: inactive (dead)
starting the tcmu-runner service does fix the issue.
I tried to add the below line in
/lib/systemd/system/tmcu-runner.service, to try to figure out
why its inactive (dead), but it didnt give me a log.
ExecStart=/usr/bin/tcmu-runner > /var/log/tcmu.log 2>&1
Anyway, I added two lines into /lib/systemd/system/lio-target.service
and it seems to fix it.
Requires=tcmu-runner.service
After=tcmu-runner.service
Now on startup of target:
