Hi, We are using an old Vaxserver 3600. We had a power failure and the battery backup ran down. I cannot boot as dia0 (system disk) is not available. The power up boot sequence gets to 3... and fails with the statement "Normal operation not possible". I can get a partial boot off another disk but I get the following messages: % PIA0, DSSI terminator power failure possible blown fuse % PIA0, Port is going offline Anyone have any ideas? I cannot find any fuses anywhere. Regards, Mike Broga

Disk DIA0 means that you are using a disk on a DSSI-bus. A DSSI-bus needs to be terminated in both ends..... is it ? How is your system configured ? Only one box ? How many disks ? Have you tried to remove all disks, except DIA0 ?

Additional information. The system is in one box. There are 7 hard drives. Five in a separate bay and I can see all of those. These are on disk controller 0. If I run "sho dev" at the ">>>" promt disk controller 1 is not shown. It should have 2 disks and a TK70 tape drive. As far as I can tell all of the terminators are in place. Regards Mike

If you got a HW-problem......it can be difficult to help. What you can do to get your system up and running, is to replace the disk with unit 0 on the other bus. What kind of system are we talking about ? Is it a productionsystem or a hobbyistsystem ? Any HP HW-support-contract ?

Mike, Ok, for starters, I am a bit suspicious about power. You say that you have two cabinets. Can you verify that the second cabinet powered up? Also, is anything else amiss. Sudden power downs are always a potential for hardware problems. Digital engineered things very well, but I have seen some strange problems creep in. At one client last year, a machine (in this case a MV 3400) developed a flakey power supply after essentially a decade of reliable operation. In this case, it manifested as a series of unexpected Machine Checks. What does the console show when you display devices? - Bob Gezelter, http://www.rlgsc.com

The reason I ask is that I used to work in the VMS Support Team at Digital/Compaq/HP. Even though I worked with SW-support, our databases were helpful when searching for HW-errormessages. Can't do any searches anymore.....just try and error/success
