• After any changes to Windows SMB client or account SMB multichannel configuration settings, you have to unmount the share, wait for 60 secs, and remount the share to trigger the multichannel.
• For Windows client OS, generate IO load with high queue depth say QD=8, for example copying a file to trigger SMB Multichannel. For server OS, SMB Multichannel is triggered with QD=1, which means as soon as you start any IO to the share.
