Hi, I was wondering if anyone was using a HP Disk Array Model 20 (A3389A or the newer A3550A with the new SP620 controller) on a HP3000 & MPE. Specifically: 1. After installation what use is a permanent console 2. What configuration is best (I believe that there are various types) 3. Can you use a "hot spare" drive in the array ? 4. Performance of 16mb cache v's 64mb cache 5. Any other details / experiences that you have had. There does not appear to be any Australian users of the Model 20 on MPE systems so I thought that I would ask the learned folks on HP3000-L. It also appears that you need MPE/iX 5.5 and Power Patch 1. tia peter dewar
