PDE not accessible: Cannot open PDE device

Hello all!

In my laptop env I have TD 13.10 version. After some reboots, Teradata didn’t start properly. So, when I issued

s10-1310:~ # pdestate -a
PDE state: DOWN/HARDSTOP
s10-1310:~ # /etc/init.d/tpa start
Teradata Database Initiator service is starting...
Teradata Database Initiator service started successfully.
s10-1310:~ # pdestate -a
PDE state: DOWN/HARDSTOP

Interesting…

So, I began reading OS logs first. Check out this:
/var/log/messages:

I deleted this file and now, everything works fine! So, be careful with reboots. Now, you are know how resolve this issue.

Regards,
Pavel.

  1. Many thanks. I had the same problem with TD 14. deleting “/var/opt/teradata/tdtemp/PanicLoopDetected” solved the problem.

  2. Thanks.. It worked 🙂

  3. Здравствулте!

    You should check what caused the panic state before starting PDE.Panic state is not peanuts! 😉
