[ISS Support Case] Historian Missing Tags
Last updated: March 6th, 2025Description
Client called in due to noticing they were missing around 37,000 tags and only had around 7,000 showing in system since yesterday afternoon. When inquiring about any recent changes client stated that they were attempting a bulk import yesterday when they received an error. They are unsure of the exact error but client stated it was something along the lines of "Cannot reserve the .LOK file." They believed the error was due to a lack of space/memory or too many nodes in the importer so they deleted 10-15 of the nodes which I believe were tied to the missing 37,000 tags. Attempted to query some of the missing tags using query and no data was returned for tags for live or historical values. Believe that nodes will be need to be readded to import tags or possible backup restoration on system?
