This article provides steps on how to disable auto-update of comments every time IPAM scans the subnet.
All IPAM versions
1. On the Manage Subnets and IP addresses page, click the subnet that you want to disable auto-update of comments.
2. Click Edit on the upper-left corner of the page. A Edit Subnet Properties window prompts after this.
3. Scroll down to get to Automatic Scanning section then choose Update but not erase manually entered data. See attached image for reference.
Choosing this option prevents the application from deleting any data fill out in the Comment field. However, the difficulty lies when there are thousand of subnets to be updated with the same scenario above. Use this query below to update the database setting of your subnets.
SET RetainUserData = 1
WHERE GroupType = 8 AND RetainUserData IS NOT NULL
Note: Replace [SolarWindsOrion] with the name of your Orion database.
