Update: |
| 18 |
|
| 19 |
I updated the software, and the next morning the server was down again. |
| 20 |
Yesterday, I pulled the disks and put it into another, identical HP Z800 |
| 21 |
which so far has been running without problems. |
| 22 |
|
| 23 |
It didn't go down yet, and there is one peculiarity: |

Why do I get a message that the link is up? |
| 68 |
|
| 69 |
There is no message that the link went down. I checked another server |
| 70 |
which is connected to the same switch, and the link on the other server |
| 71 |
didn't go down and didn't come up, i. e. it was persistent. |
| 72 |
|
| 73 |
6:45 is a suspicious time, but I haven't found any cron job which |
| 74 |
might do something with the network card. |
| 75 |
|
| 76 |
What might have happened here? Could this be some event which made the |
| 77 |
other HP Z800 go down? |
