It would seem that you lost your battery back-up. But, to your question, here's a basic look at what you want to do: >> scsi pb This is the SCSI PROBE command (for the DS2100/DS3100 series PROMS) and will show you what is out on your SCSI bus. While it will not fix the problem of having two SCSI devices set to the same SCSI ID# it would have told you that you were not seeing all of the devices that you had connected. I don't know what version of console firmware you have (I think we are up to v7.3 or so, but since I have a DS5000 :-) I'm not that certain of PROM level's on the older systems) but I remember that with PROMs below v6.1 (or thereabouts) you needed to do an init before you booted when you had been running any of the tests in the firmware (some sort of weird state having been left by the tests). The command would be: >> init You would then see a reset that would respond with the KN01-AA as the processor, your console PROM version and your ethernet address. To see what has been set for a bootpath on your machine, you can use: >> printenv bootpath From your note I would gather that your's would respond with: >> bootpath= You could then do a: >> setenv bootpath= -f rz(0,N,0)vmunix -a Where N is the SCSI ID# of the drive you are attempting to boot from (the first 0 in the parentheses is the SCSI bus ID#, as we had plans for additional SCSI buses being available on later products, I don't remember what the final 0 is...senility is so hard to live with). The -a switch will bring you up in multi-user mode while leaving the file pointer at just vmunix will bring you up in single-user mode. The PROM code on the DS5000 series (Models 120,125 and 200) is, in fact, different. It wasn't changed just for fun. We needed to open up the interface for Third Party Hardware vendors who wanted access to TURBOchannel. Your options there would be: >> cnfg This is the "configuration" command that will show you the system's configuration. It will report on options, both base system module and the configurable TURBOchannel slots, that it finds at the various TURBOchannel logical addresses. To see a detail on a particular option that is present you would do a: >> cnfg N Where N is the number of the option that you are interested in (in the case of the base system SCSI bus on a DS5000/200 it would be: >> cnfg 5 A logical boot sequence for your case might be: >> boot 5/rz4/vmunix -a This would boot the system off of your RRD40/RRD42 at SCSI ID#4 and bring the system up in multi-user mode. While a network boot would be: >> boot 6/mop To set your boot environment on any of the DS5000 series machines the command is: >> setenv boot=X/rzN/filesystem -a Where: X is the TURBOchannel option you want to boot from. N is the SCSI ID# of the device you want to boot from. filesystem is the name (usually vmunix or genvmunix) that you want to point at. -a is the multi-user mode switch. I know that it all seems a bit cryptic. That's on purpose, but slightly out of our control. Certain countries stipulate that if the console code isn't supported in their native language, it can't be English. So, we take the vowels out of most of the commands as a means to comply. I didn't mean this to go into a tutorial...it just sort of happened. I hope that this helps.
