Yesterday was a day of unwanted learning experiences. A less charitable observer would have termed them ‘massive fuck-ups’, but I think I learned plenty.
In particular, I learned that one of our Netfinity 7000 machines has the hot-swap SCSI arrays wired backwards compared to all the others. This, in turn, enabled me to learn all about recovery procedures for disk arrays. I am very happy that I had chosen to set up the machine in question as a RAID-5 array.
