BFT failure or HDD failure?
BFT failure or HDD failure?
(OP)
Hello gentlemen, hope everyone is doing well.
Got a question about a BCM450 6.0 system -
When a BFT fails, how do the symptoms differ from when an HDD fails?
How does a technician know it's the BFT and not the HDD? Or vice versa?
Got a customer with a BCM450 6.0 that's been acting erratic and just trying to prepare myself in case the system crashes.
Thanks in advance.

I have seen flaky power connections behind the MBM slots, and bad power supplies, so those are other things to check.
Give the alarm log a look when you first get there. It might lead you toward the problem. Good luck!

ucxguy - the customer tells me that once every couple of days all the phones will "freeze up" where none of the buttons work on any of the phones. Any call in progress is lost. Indicator lights and the time and date are also "frozen". The customer will power cycle the BCM and it will come back on as normal.
The system has around 60 T7316Es and a PRI.

RE: BFT failure or HDD failure?
If everything suddenly "freezes", the reason usually is that the Linux OS stopped working (due to "kernel panic", lockup of an I/O bus or something similar) and with that all applications that were running. It is not simple to determine where the actual problem is. It could be power related (so you could try another power supply), it could be a bad memory stick or it could be some corrupt executable being read from the hard drive.

If the system continues to do this, I'll replace the power supply. If replacing the power supply doesn't clear the trouble, I'll try replacing the hard drive.

Boot the machine to a Memtest86 diskette/USB stick/CD/whatever and let it do a few passes of the memory that's in the box. Have you considered converting this machine over to SSD as well? What kind of environment does the BCM live in? It is also likely time for a CPU repaste, especially if it lives in a dirty/hot environment.
