Applies to

  • ONTAP 9
  • CIFS
  • Vscan

Issue

  • Customers have reported latency on volumes when AV Scan is enabled
  • Slow performance / High latency in CIFS, introduced by Vscan
  • Enable additional logging on the AV server
  • In the log file, observe if the pipe connection to ONTAP was already established by the registration of the interface
  • Later in the log, check if a second pipe attempt was made to establish, which failed.
  • Errors may be seen like below:
