- We have recently bought a couple of 425e's. Seeing HP's prices for things
- like disks and memory, we decided to purchase 'minimum-configuration'
- machines, with the idea of adding third-party bits-and-pieces.
-
- I am having some trouble creating a disked 425e. I can easily plug in the
- disk: the power supply cables are in place, the SCSI connector is there.
- (The SCSI cable I used is a straight-through cable: connects pin 1 on one
- connector to pin 1 on the other, same as in a DN2500.) The problem is
- probably not one of terminators: the terminators are in place on the (only)
- disk drive; it does not matter whether I plug in or not a terminator at the
- back of the machine (into the external SCSI interface). The problem is
- unlikely to be the type of disk I used: I also tried a Rodime drive (which
- is a spare for a DN2500).
-
- At the power-on (ROM) self test, the node displays
-
- HP98265 (SCSI S 32) at 14
- register test failed
- ...
- STORAGE DEVICE TESTS STARTED
- HP_$SCSI_SC_INIT: error
- SCSI bus init routine failed
- Storage Devices - ABSENT
-
- If I use 'DI N' and then 'TE' at the MD prompt, then it will also run the
- loadable self test, at the end of which it will display
-
- -- Failure List --
- SCSI Device ID 7
- HP98265 (SCSI S 32) at 14
-
- The disk used is jumpered to be SCSI ID 6 (and this last message does not
- change if I re-jumper the drive to ID 5).
-
- The node will not run: after 'DI N', 'EX anything' it will show the dots
- while loading, then the line 'low high start', and then it just hangs.
-
- I thought this might be caused by some jumper or setting on the 425e. But I
- cannot see any jumpers that could be changed. (There are some jumpers next
- to the ethernet connectors, but they are supposed to be the selector between
- thick and thin ethernet. Also there are two DIP switches, but they must be
- related to video mode selection: one switch is labelled 'C' and 'G' (color
- or grayscale), the other '72' and '60' (Hertz).)
-
- The 'CF' 'I/O Configuration', 'SCSI' command shows (correct?) default
- values:
- Select Code 14
- Interrupt Level 4
- Parity Y
- Bus Address 7
- (The LAN SelectCode and InterruptLevel are 21 and 5, the HP Parallel ones
- are 12 and 3).
-
- (Obviously, if I unplug the disk the node will work properly.)
-
-
- Can anyone help me to get the disk going?
-
- Thanks in advance,
