3COM NBX (V3000) gets hung!

3COM NBX (V3000) gets hung!

3COM NBX (V3000) gets hung!

We have an older V3000 NBX. I recently added a 72" rack in the server room, to alleviate a space problem in the MDX.
When I re-started the NBX, I get errors. I stumbled into a workaround, through a console and Putty (EXE). When the system boots, is does a lengthy disk check, and while doing that, it freezes during one or more of the processes it does during boot.
All I did was hit the "CR" key when I get an error message and it would continue to the next process, or free up and start working. It is random when it freezes, and usually I can hit the "Enter" key enough to free it up.

Any crazy ideas? I am out of them...sad

RE: 3COM NBX (V3000) gets hung!

I can only surmise the NBX V3000 is similar to the old NBX 100 and 5000 in software design. When the system software was not shut down via the browser (like in a power failure), the system will perform a system file check upon the next startup. We had a few systems that would take a good 60 minutes to boot. There were 6 phases of the system check and I remember Phase 2 and, on occasion, Phase 6 would take a long time.

Maybe the system is hanging because this check has not taken place and file repair performed.

We have one V3000 out there but it is battery backed up to the hilt and the customer religiously shuts down the software during any planned outages for this very reason.


RE: 3COM NBX (V3000) gets hung!

I did try a "Graceful" restart, but it hangs during a the Disk-Check. When I hit the enter key several times, it does this:
no current record
C errno = 0
press return to continue


Once I hit the Enter Key it returns back to the command prompt.
I noticed this morning that only when the receptionist opens the lines up from the automated attendant over night. Then when the office shutsdown at night, the ladies put on the voice mail, and it hangs again.

RE: 3COM NBX (V3000) gets hung!

It "Un-Hangs" when I hit the "Enter Key' and continues to function properly so far, until the voice mail is enabled. I have heard of other features hanging up....yet.

Try to stop boot , configure NBX to start with previous release

Press any key to stop auto-boot...
