      We still need to see the logs 🙂

      [root@xen2 ~]# tail -n 100 messages
      tail: cannot open `messages' for reading: No such file or directory
      

      That's not good. That means that something really went wrong. Probably the disk had filled up.

      Is there another way to view log entries?

      Not if they are not there. That's not a log viewer, that's the logs itself. Are you use that you used the cd command to get into the right directory before trying to view the logs?

        I used no cd command. I just tried "cd /var/logs" and was told there was no directory.

                We still need to see the logs 🙂

                [root@xen2 ~]# tail -n 100 messages
                tail: cannot open `messages' for reading: No such file or directory
                

                That's not good. That means that something really went wrong. Probably the disk had filled up.

                Is there another way to view log entries?

                Not if they are not there. That's not a log viewer, that's the logs itself. Are you use that you used the cd command to get into the right directory before trying to view the logs?

                I used no cd command. I just tried "cd /var/logs" and was told there was no directory.

                We are definitely seeing a problem here 🙂

                    No idea, but it's not from ML, that's from his cut and paste. Those spaces are all in his original.

                          @CitrixNewbJD said in XenServer 6.2 servers down. I have no Xen skill. Most likely networking? Help!:

                          Better?

                          Yup, thanks.

                            We need to see the Xen logs, too. Those are the logs with "xen" in the name.

                              I can't upload the .gz to here. Can I open the contents in wordpad? Sorry if I missed something.

                                  It ate my text. How do I display the logs to you? Sorry. A lot of new knowledge in a short period of time, combined with stress.

                                      Sorry, ate my text again. Unless I should be looking somewhere else...

                                        Is there any way to tell why the hosts can't even attach to their own local storage, or why it was unplugged in the first place?

                                          Get us the SMlog tail...

                                          tail -n 100 SMlog

                                            Then let's see what is in the xen folder, too.
