Mathes,
Thank you for the detailed answer. I think you need to ask the Invensys =
Reps why they think that a Day0 install on the AW51G is going to fix a =
FOLAN problem. Perhaps they can tell you why the replacement of the hard =
disk has caused you to see FOLAN problems, but in my opinion, you have =
two separate and distinct issues that happen to have started about the =
same time.
The proposed solution seems risky to me. The risk is to your controllers =
which are actually running your plant. Your problem is with a FOLAN =
that fails to single (yet keeps communicating) once in a while. The LAN =
failures do not halt your production, but a controller failure (a risk) =
will likely halt your production.
What steps have been taken to investigate the FOLAN failure to single? =
Did anyone enable nfd_log and nfd_debug log ? Did anyone suggest =
marking the FOLAN stations as "FAILED" in the IIF.cur file and =
re-installing just the FOLAN files ?
Has the local Invensys Field Rep contacted his TAC group with a written =
upgrade procedure so that the TAC can comment on the plan?

Dear Terry,
=20
Thanks for your input. The AW is currently working and all the backup =
data are uptodate. This plant is using P81 RED BOXes. Few months back =
there was an AW failure and the service team tried to restore with a =
SILVER box. But it didnt work. So, they just replaced the harddisk from =
the silver box to the red box and the AW seems to be working fine.=20
=20
But after this restoration, FOLAN seems to fail to single very =
frequently. Our local service team tried to fix the problem and tried =
various fixes. Still they could not resolve the FOLAN problem. So they =
want to do Day0 committal on this AW to fix the FOLAN. I am not really =
comfortable doing this and thats why I querried in this forum.
=20
We think of doing this as follows.
=20
1) Day0 committal Installation to 7.0
2) Release update to 7.1.1
3) Copy the Checkpoint files & Workfiles from the latest backup =
(backup just before shutdown)
4) Copy the display files & custom files
5) Re install AIM * Historian.
=20
I have done this work earlier, but I always did =
Initialise/Reboot/Loadall of all CPs. In this case I cant do any reboot. =
Will appreciate more input from the forum to help me resolve this.
=20
Thanks once again.
=20
Regards
mathes

Mathes,
You should really contact your Invensys Field Service Rep to get this =
=3D
done correctly. Even if you can reboot the CP's, a Day0 is done on V7.1, =
=3D
not 7.1.1. (Release Upgrade) How up-to-date are your SAVEALL files? =3D
What about display files and historical data?
If you try to go the no reboot path - where are you copying the work =3D
files, etc from? How up-to-date is that data? If you can copy from the =
=3D
original hard disk, why not copy the whole drive and just boot your =3D
AW51G from that drive? If the drives are different size, there are some =
=3D
tricks in the Cassandra archives that can help get the new drive =3D
bootable.
This is not an easy or trivial task. You have a running plant and you =
=3D
would like to have the plant running in the same manner after your "fix" =
=3D
of the AW51G. You likely need the Invensys Rep to help.

Dear All,
=3D20
Happy New Year to all of you.
=3D20
I am Mathes from Foxboro Malaysia. I need expert opinions on the =3D
following problem.
=3D20
In one of our site, we need to replace the existing harddisk & do Day0 =
=3D
commital installation of AW51G (P81 RED Box) with IA 7.1.1. This AW is =
=3D
hosting CP60FT, CP40FT, AB30FT, FD30 & MG30FT.=3D20
=3D20
Can we replace the harddisk & do Day0 Committal installation of this =3D
AW without Initialise/Reboot/Loadall of these controllers?. By copying =
=3D
the checkpoint point files, workfiles, & other custom files, is it =3D
possible to complete the installation & avoid station reboots?
=3D20
Any opinions/suggestions?
=3D20
Thanks & Regards
mathes
