How to remove Snapfix from PI tag even I restarted both interface node?
How many PI Tags are you seeing the Snapfix event? Also did you perform a snapfix recently on your PI Data Archive? If not then please describe the method in which you induced this snapfix events.
For your information the snapfix event will automatically disappear from the PI Tag once new snapshot (actual value) events arrive for these PI Tags.
If you still wish to manually remove the snapfix events then if it is a few PI Tags that you are seeing Snapfix then you can simply use PI SMT >Data > Archive editor, find your PI Tags select the snapfix event then delete it.
If you wish to perform the procedure for all of the effected PI Tags then please see KB00848 - Backfilling with PIconfig section titled "Clearing the "Pt Created" snapshot for new points" replace all references of "Pt Created" with Snapfix.
Let me know if you have any further questions.
Yes, snapfix event done on 22-oct-2016 on PI Data archive.
But ,3 out of 5 secondary Interface node(Healthy Point) still shows in snap-fix. Snap-shot attached for reference.
how can I verify interface node working or not ?
From your screenshot, the date on the snapfix is 22-Oct while the machine clock is showing 28-Oct, have you tried refreshing the health points (right click on the health point row and select refresh)?
Furthermore the interface startup logs (PI Message logs on the interface machine) will show messages indicating how many health points are loaded on startup therefore if the interface did not load the health points on start up for some reason then the points will not update, if this is the case then why the points failed to be loaded by the interface needs to be investigated.
Besides the health points you can verify the status of the interface by looking for a device status message on the PI Message logs that gets written once every hour DeviceStatus=0. If you see another code then this indicate that there are issues that may require attention. Any interface operational errors will also be written to the message logs.
I tried for refreshing as well as deleted & created again . but now its show PI Created.
When I was restarted the interface , it try to make primary but redundant interface in primary state.
It gives current status: "Backup"
but still snapfix or PI created on update. Please help to resolve the same.
