icomlx11 has been decommissioned.


It was also known as the Video Team Server, is a server Jonathan built. The X: and R: drives are hosted on it.

  • Online & mountable
    • Machine is powered
    • Web interface is up
    • Drives are up
  • Online not mountable
    • Machine is powered
    • Web interface is up

    • Machine is powered
    • Web interface is down
    • Drives are down

X: & R: down

Symptoms:

  • icomlx11 status
    • Online not mountable
    • Hung
    • Powered down

Solution

Steps:

  1. Reboot with IPMI
    • As per the note in Admin tasks
    • The server has problems mounting the drives so warning several reboots may be required
  2. Check that the Web interface is up:
  3. If it does not come up then return to step #1
  4. If all else fails use the power switch until the monitor show a signal

Black screen

  • For what I saw the issue happened.: First, Aaron's computer was frozen.Then the whole video team's computer can't connect to icomlx11. After they reboot the machines, the computers hanged on the logon and showed black screen. Then we checked the server, the server had some issues, and couldn't be connected.
  • (I think the reason caused this was 1 machine(Aaron's or icomlx11) had some issues and sent a lot of messages to the network (the 3 machines try to connect to the server) made the switch frozen or not responding (flooding). I tried unplug Erik's network cable, it was able to logon use cache setting.)
  • This is just my imagination, might be wrong.

Solution

  • Check if the server is working fine, if not, reboot it (may need several times). Reboot the client machines (Video team)
  • From windows explorer: type in \\icomlx11, If you can see a shared folder called VideoTeam, it's working fine
