[rescue] rescue Digest, Vol 244, Issue 3

Hi

As a bit of an aside. We were Solbourne agents early 90s and won a UK  University contract for one of the largest systems they ever produced. The spec included a lot of IPI drives but the Seagate ones were pretty pricey even direct from Seagate. Fujitsu also supplied IPI drives and had some stock they wanted to move. We installed the Fujitsu ones and I spent a number of days commissioning the system. The only issue I had was on running format read/write test on more than one drive at a time the system would crash. Eventually we admitted defeat and swapped out the Fujitsu drives for Seagates. We then could not fail the test. However just after this I learnt from someone in Solbourne that you could crash it with Seagates and that it was an issue with the raw disk driver and that in normal operation the Fujitsu drives would have worked ok. I hate to think how many hours I spent chasing that problem…….

The only companies I came across using IPI were Sun and Solbourne
