Retrieving data from a Nortel application module hdd

[martinduchesneau]

Hi all,

I don't know if anyone ever attempted this and got good results, seems to me like a possible thing to do. We have a client with a rather complex NAM setup. Unfortunately the hard drive is at the end of it's life. The NAM is very slow.

For exemple, if a caller dials a DN during an AA prompt/SS, it can take up to 3 minutes before the system transfers the call. If a user dials F981 to retrieve their messages, or F983, same thing. Fortunately enough a backup was made using F983, 33 before things started to be slow. It's acutally after loading the backup on another hard drive in the same NAM that we figured the problem was with the Hard drive. Unfortunately tough, the backup is so-so, we need to rebuild all AA tables and every mailbox :\ but we still have all voice prompts recorded by the client

Rebuilding the entire system will be very fastidious work and I was wondering if it was possible to recover part/all data from a corrupt NAM hdd and use the "not-corrupted" data to rebuild from there.

I'm sorry for the long post but this is a very complex issue. If anyone has ever tried this kind of stuff with a NAM hdd please share your knowledge.

Thanks alot!

Why would you do a back up on a corrupted hdd and then want to restore it to a new one...Thinking is very flawed.How did u determine what is good and what is bad?

Actually I don't want to back up everything, just the voice prompts and mailboxes, or what's recuperable. This is what we wish for of course, but I'd take anything.

We tested the hdd in another NAM and the problem is the same, then we tested another hdd in the "troublesome" NAM and everything was fine, data and programming of the previous instalation. This is how we figured the problem was with the HDD.

If you think the problem is not with the hdd, please tell us what you think it is. We're in the process of rebuilding from 0 right now so before we go too far with this it would be good to know.

I tought this place was to share knowledge and get answers to problems, not get insulted from someone who did not do the tests that we've done. I don't usually draw conclusion too quickly so don't go about saying my reasoning is poor lugerlover.

my apologies, there are alot of uneducated wannabee's and was not questioning you abilitys.
If you think you have a corrupted harddrive than do not try a backup and restore just rekey from scratch...ccr tree and tables should only take a hr or so and mailboxes the same...voice prompt are not issue put customer on it and have them rewrite script..also perfect opportunity to revamp ccr/aa...mboxes just initailize to ext name and have customers rerecord there prompt...if you lose old messages remind users vm not a rolodex. after a week do backup

Apologies accepted lugerlover,

Thanks for the advice, it's what we did actually, it would have taken too much downtime backuping and reloading data anyways, it was just for personnal culture. Overall it took us 12 or so hours rebuilding the config.
