Technical problem vantage

The first rule of NT is never use the NT FTdisk.exe to mirror drives
(Mirroring via software is slow and not that reliable).

If I remember, the NT mirroring S/W will always rebuild the mirrored drive
after a dirty shut down.

Since you did not mention any events of actual hard drive failures, NT would
use the drive with address value 0 as the master and value 1 as the
re-mirrored slave. If the 8 hours of data are not on the master drive or
backed up somewhere else then it's lost forever.

After all that, I don't think FTdisk.exe was the cause of your data loss.
But it's a a good idea to spend a few bucks and get a hardware mirroring
solution.

Good luck,

Jerry Solobay

Here is an "interesting" occurrence that will hopefully never happen to you.

We are running as our Vantage server, an Intel LB440GX motherboard running
dual P3-600 and 512 meg of ram. This is inside of a 2U rack mount chassis
with two 9gig drives running a RAID 1 software mirror via NT server.

Approximately 24 hours ago, the Vantage server began submitting SAM database
update from the Primary NT server. Over the course of the next 24 hours, the
Vantage server would request a new update every 10 minutes linearly
increasing the number of update it received back. Nearly 16 hours later,
Vantage crashed, and none of the users were able to work in Vantage. This
failure went unreported until 8 hours later. There was an attempt to
shutdown the Vantage server which ended in a Blue Screen of Death. The
Vantage server was then shut off and brought back up normally.

Everything appeared to be working fine, but the event log showed that Ftdisk
had begun Mirror initialization on boot. The end result is that we are
currently missing exactly 1 day worth of data.


Has anyone ever had this happen before, if so what did you do?

ANY and all answers or suggestions would be very very helpful.
I had a somewhat similar event last week. My Vantage server kept loosing
it's link to the network. the system locked up three times until I
determined I had a bad cable or connection from my server to the switch.
Did you install any new software lately? I'd swap that cable to that server
just to rule out that variable.

Approximately 24 hours ago, the Vantage server began submitting SAM database

I forgot one thing. It is normal for your NT server to request SAM updates
every hour from the PDS. Mine updates every 43 minutes after the hour,
every hour.
