Restored DB and now cannot find NAD in the database

[martucci]

Hello,

i have build a brand new ISE 2.2, and imported a backup from 2.1.

All seems ok, but I am seeing all my events dropped as seems ISE cannot find the NAD in the DB.

The devices were there, and even after delete them and re adding them, I still have the same error.

Is there a way to recover from this and how could it be done, prior to me trying to restart from scratch again?

Thanks a lot

Hello, an update here on my ISE.

I built it from scratch (2 nodes, one PAM and MnT, and another server being PSN).

I did create the cluster (registered the PSN to the PAN), and then run the restore.

(When  I run the backup the cluster was in the same situation).

After checking better, I have realized that now my PAN does not see the secondary, and it is in standalone mode again.

The PSN is thinking it is a PSN, so I have the restricted GUI when logging on it.

I have made my PAN a primary again, but of course I cannot add the secondary as it is not in standalone mode.

Is this a bug, or is procedure that I should first do the restore on the standalone and then add the PSN?

On the User guide is not clear as when I look for restore on distributed deployment, it is talking only about primary and secondary, but does not mention PAN and PSN being in different boxes.

Thanks a lot

If hostname/domain name changed, then it's possible the restore made the primary standalone. Did you include ADEOS data during restore?

Thanks Hsing, hostname/domain and IP did not change.

I tried again and this time I selected to restore ADEOS as well, but it might be that I did not take it in the backup.

After restore I had the same issue, PAN and MnT were in standalone, while the PSN was as a PSN, but not added to the PAN (as that was in standalone).

what would be the best course of action for the restore?

Should I put the PAN in standalone, restore and then add the second one?

Or will that be an issue as the backup was taken in distributed?

Another option could be for me to go to the original server (2.1, still have the VM), put it in standalone, run the backup, then restore in standalone and recreate the cluster.

But I would like to understand like it should work normally.

thanks a lot

It might be due to upgrade (2.1 to 2.2). I would suggest you to try restoring the 2.1 backup to a standalone 2.2.

Thnks Hsing,

I did not upgrade, I did a fresh install. At the end I did restore on the standlone fresh 2.2 image, and only after I aded the PSN and all seems to be working fine.

Thanks for the help
