Disaster by making all access point config default

There can be an instance where someone selected all the access point in the hivemanager and done default config. It will be a big disaster. Is there any way to recover from this disaster if it happens so we can be prepared for this kind of disaster.

You can't select more than 25 APs at a time for changes. Therefore, it isn't possible to change all of them in one action unless your network is small.

I'm able to select more than 25 APs when I make changes in HiveManager.  All of our schools have way more than 25 APs and I can select all of the APs in a school to update them after making changes.

Hi Rob,

Poor wording on my part -- you can select as many as you want, true, but have you tried to initiate an update after? The update will limit you to 25 and you have to deselect down to that number. 

Apologize for my confusing wording...

Yes, I have done an update when selecting more than 25 APs.  When I look at the update status queue, it shows me that it only updates so many at once (not sure of the exact number), the rest are in queue and as the first batch finish updating it moves on to another batch, but I don't have to do anything for the rest to update and I don't have to deselect down to 25 APs.  I'm on HiveManager 6.5r1 but this was even true when we were on 6.4.

Rob is correct, you can select as many as you want. There is a bug in the more recent builds that even if you select all devices it doesn't select them all. I'm on 6.6r3 and it is still there. But you used to be able to select all your devices (I think anything prior to 6.6).
The current limit to select is 500. HM will update 10 at a time. So your first 10 will be updating and the rest will be queued up.

One way is to make sure you are doing database backups on a regular basis. Then you could always restore from backup.

But you can help prevent this by limiting who has access and to what they have access to in HiveManager.  If you're worried about certain users making a mistake, make them Monitor-Only so they can't make any changes.

I dont think the database backup can avoid this kind of disaster as the default config command will be already passed to access point and there is no way to rollback the config of access point. The database backup can be done for the hivemanager and this disaster doesn't relate to that.

I think there should be an option to save the config on the access point so in case of disaster the hivemanager can trigger that option to rollback the configuration. This feature is required in NG hivemanager.

The database backup does relate to this disaster. If you accidentally defaulted all of your devices, you would then restore HM from backup. The HM backup has the configs of all your devices prior to defaulting them. So even though the devices have no (default) config, when they connect back to HM, they would show up in HM with an audit mismatch. At this point you would then push the config to the AP and you would be back in business.
If you would like to see this in action quickly without going through all the steps, console into an AP and reset it to default. This would be the same situation as if you had reset it to default in HM and then restored the database. You see that in the AP console session it has no configuration. But in HM you still have its configuration, and you just need to push the config back to it.
