BCM 4.0 Hard Drive Issue

[Dasheen]

Hey guys I wonder if u agree that the HD probably needs replacing even tho it's only 2yrs old.

A month ago I tried to do a backup but at the very end it gave an error saying could not be completed. During the attempt it turned off the vmail services and never restarted them. I had to do a reboot. After 1hr of watching the HD restart VERY slowly I left the site w/ the vmail still down and the HD booting up. Process took over 2hrs.

I returned today to load SU27. Patch installed ok but again the HD took forever. I watched the startup via Procomm and things were moving at a snails pace from the autocoreload service on. Each service was taking up to 10min to come up as ok. The HD took 2.5hrs to come up but the vmail service was still down and so were several other services (Utfp, UTFP server, ip services, etc) Even tho the alarm table showed callpilot was restarted successfully, vmail was down. I went into services and manually restart it. After 1hr the vmail was up. Only things is I can't get in via EM says Vmail is restarting please wait 5min. If I go in via Telset, I can get in.

So what are your thoughts? Replace?

Could also be the power supply. Also, check the alarms for thimgs like insufficient disk space and hi-temp alarms. Were you ever able to get a good backup?

 

[Dasheen]

none of those have appeared.

If you have a recent backup, you may want to try to default the system before replacing the HD to see if a clean data base corrects the problems.

Check your AC socket if it´s grounded,also check AC Volts between ground and neutral not be > 1 VAC

There are no power related alarms. I've been told to replace the HD as it sounds like corruption. Once replaced, I'll let u know the outcome.

the bcm50 must be powerd down for at least 2 minutes before restoring power.

This is a BCM 400. Could the PECs cause issues like I've described. I logged into BCM Monitor today and saw PEC3 DSP 1 as out of service. Need to compare to another BCM to see if it's normal.

It happen to me twice in the past that weird issues were caused by PEC cards not well seated.
Once the back fan broke and was doing a lot of noise with vibrations that manage to do a bad contact between the PEC card and the PEC connector.At that time the symptom was i was losing all my services.After reseating both PEC card the Bcm ran fine.
The other time i could not receive more then 3 calls on a PRI(all other calls were intelligible).A new DTM didn't fix the problem.
After being close to replace the cabinet i thought of reseat the PEC card and to my surprise it cleared the problem(that was going on for 2 weeks).
I never thought a PEC card could cause a problem on a PRI before this happen to me.
So yes i would reseat the 2 PEC card's(swap them at the same time.)but if that doesn't fix it i guess you'll have to replace the hard drive.

In reality, it could be any number of backplane/connector issues. I had a DTM that lost clocking from the PRI daily, sometimes several times each day. I replaced the DTM twice, each time it was ok for about a month and the trouble started again. I replaced the cable to the IAD twice and the service provider replaced the IAD. I finally replaced the cabinet and reused all the electronics from the old cabinet and it hasn't given me any trouble for a year, so I'm guessing it was a connector issue. I just hope this didn't jinx it.

FYI

It was a PEC problem. While waiting for the HD to arrive, I found an old PEC card and tried swapping out the possible defective one. One swapped, HD & vmail came up within 10min. Also managed to get a backup.

First time I've ever encountered a bad PEC and I've been working on BCMs since 3.5.

That defective PEC card is probably good.Reseating the PEC usually does the trick.
Glad to see you fixed your problem.
