One of it&#8217;s nodes has been down since I started work here and I&#8217;ve finally gotten around to looking at it.<\/p>\n<p>Step 1 was to try and get acces to the serial console. After hunting around for a cable I then had to fight with minicom to get it running. A process that would have been significantly easier if the terminals weren&#8217;t all runnning at a non-standard baud. Anyway a quick re-boot of the machine showed that it was finding it&#8217;s internal disk but failing to find it&#8217;s OS. Given the number of times the power has failed recently I wouldn&#8217;t be at all surprised if the partition table is corrupted. So it seemed like a re-install was worth trying before getting a replacement disk.<\/p>\n<p>After finding a set of <a href=\"http:\/\/www.futuretech.blinkenlights.nl\/6.5inst.html\">Irix install instructions<\/a> that I could actually understand I hooked up the ancient external SCSI CD drive and put in the disk that contains the install tools. It took a couple of attempts to convince the drive that it should close but after that it made all the right kinds of whirring noises and I was quietly hopeful.<\/p>\n<p>So boot to the command monitor and:<\/p>\n<p><strong>boot -f cdrom(1,1,7)sash64 <\/strong><\/p>\n<p>And the monitor helpfully responds with a &#8216;no media found&#8217; message. After trying several other CDs I realized that I couldn&#8217;t even ls them never mind run them. The conclusion? Knackered CD drive.
