The Question is:
Alpha station 500 hangs at "Jump To Bootstrap Code", when trying to reboot
after the system locked up. Have tried many of the commands listed in the FAQs
and the machine does not recognize them. There have been no changes in the
hardware configuration.
The Answer is :
The OpenVMS Wizard will assume a typical AlphaStation 500 SCSI I/O
configuration.
Your I/O system is misconfigured or faulty, or you have encountered
an OpenVMS bug. Given you had problems when you shut down -- and
assuming that a complete power-cycle does not resolve this -- some
of your hardware has failed or has drifted out of margin.
First, check your entire SCSI chain for length, correct and current
device firmware, correct SCSI termination, functioning and good
quality cabling, unit assignment and related.
Then try booting off another disk or off a CD-ROM distribution.
If you can isolate the device failure, try swapping the device to
another system, and try replacing the device with another (and
known working) equivalent device.
If disk hardware has been upgraded over time, ensure that there is
sufficient cooling available for the storage hardware. Disks can be
more easily retrofit than can be cooled, and thermal failures can
manifest themselves weeks or months after an otherwise apparently
successful (retrofit) installation.
If you are unfamiliar with hardware troubleshooting, please contact
your hardware services organization or HP Services. Expect to be
asked details of the current SCSI configuration.
