[Bug 1874270] Re: NVMe/FC connections fail to reestablish after controller is reset

[Dan Streetman]

> Dan, where can I find the location of these logs?

they should be in /var/log/syslog, and/or the journal, which you can
check with:

for all logs:
$ journalctl

just logs for this boot:
$ journalctl -b

just logs for the nvmf-connect unit(s):
$ journalctl -u 'nvmf-connect*'

You probably only really need to check the last one, to get the logs
specific to the nvmf-connect service failures.
