I was given two SGI machines from my university today, a deskside Onyx2 and an O2, and they each have some problems. The Onyx2 boots to the desktop, but after running for a while it starts making grinding noises and "FAN FAIL" is displayed on the LCD screen. After about an hour the whole machine shuts down, with a "high temperature" warning lamp lit. Obviously some sort of a fan issue, but I'm not sure which fans are failing, as the problem doesn't start occurring immediately, but after the system has been on for a while, as if the machine is switching from one fan speed to another. There seems to be airflow on the top and the bottom of the case, but it sounds like the fans are either bad, need oil, or are dragging against a cable.
The O2 I received doesn't have a fan issue, but it doesn't boot. I got this error:
Code: Select all
Unable to execute scsi(0)disk(1)rdisk(0)partition(8)/crt_ option = 1: no such device
Unable to load bootfile: no such device
I tried to fix it by re-installing the OS using the IRIX installation tools CD, but after it copied the installation tools to the HDD, it would go back to the same problem. I tried the tips in this thread http://www.tek-tips.com/viewthread.cfm?qid=643120 to fix it, but it still doesn't seem to work. I think it's a problem with the disk, as I'm getting disk parity errors in the IRIX installation boot screen (picture attached.)
I'd really like to save these machines and get 'em fixed up, but I'm not familiar with the architecture yet. I looked up the "FAN FAIL" message in the Onyx2 manual and they said I need to make a support call, but I doubt the warranty is still active from 1996. Has anyone here had either of these problems, or know of a way to fix them?
Thanks for any and all help!
