Please use our SSL secured SUPPORT REQUEST form for all support issues, or email us: info@L3server.com. Server administration is very complex. There is no way we could provide you with a full server admin guide, but below are some NOTES we hope will be helpful.

-------------------------------------------------------------
NOTE relating to the following ERROR (1/26/2013):
e1000e 0000:05:00.0: eth0: Reset adapter
-------------------------------------------------------------
If you have a newer server with us, one with Supermicro motherboard X9SCM or similar, then you may experience irregular network drops. The problem has been known since spring 2012
(see the bug report here) to Supermicro, but with our former HP switches it did occur only very seldom. Now, since December 31, 2012, with our new HP switches and new security setup, it unfortunately happens often with these new mainboards that use the default port eth0 (eth1 seems to work fine).

Supermicro has never posted a fix. However, we found the following workaround (we will implement that on your new server):

1. Login to your server as root.

2. Edit the grub.conf file:
    nano /etc/grub.conf
Add the below line to the end of the *active* (top-listed) kernel statement:
    pcie_aspm=off

Before it looked somewhat like this:
    kernel /vmlinuz-2.6.32-279.19.1.el6.x86_64 (...) rhgb quiet
And AFTER you edited it, it would look similar to this:
    kernel /vmlinuz-2.6.32-279.19.1.el6.x86_64 (...) rhgb quiet pcie_aspm=off
(all in ONE line ... a very long line!)

3. Reboot your server.

4. Check if the change worked by issuing the following command (after reboot):
    dmesg|grep PCIe
The output should look like this:
    PCIe ASPM is disabled

That's it.
