We need to remove loopguard from some DC switches,
Is there any impact of this removal -
We do not expect any STP reconvergence - but would like confirmation
Loopguard caused an outage due to a known bug in some of our switches

As per my knowledge it will not afftect the operation.
When implementing Loop Guard, you should be aware of the following implementation guidelines;
You can use Loop Guard to determine if a root port or an alternate/backup root port receives BPDUs. If the port does not receive BPDUs, Loop Guard puts the port into an inconsistent state (blocking) until the port starts to receive BPDUs again. A port in the inconsistent state does not transmit BPDUs. If the port receives BPDUs again, the protocol removes its loop-inconsistent condition, and the STP determines the port state because such recovery is automatic.
Loop Guard isolates the failure and allows STP to converge to a stable topology without the failed link or bridge. Disabling Loop Guard moves all loop-inconsistent ports to the listening state.
Please rate if it helps.
