Applies to

  • ONTAP 9
  • CIFS
  •  Continuous Availability (CA) share property

Answer

  • Continuously-Available is negotiated on the initial client connection and remembered for the duration of that session connection.
    • Once that property is removed, that does not apply to existing connections.
    • Clients that have negotiated Continuously-Available will have to be reconnected to force it to connect without it.
    • To be absolutely sure that the clients connect without CA share capability, a client reboot may be required.

WARNING

  • Due to bug 1097331 we changed the default CA share output if no open files are present from YES to NO.
  • If you are on a version prior to a fix for bug 1097331, verify if #open files are greater than zero before attributing to a CA connection.

Additional Information

  • The ONTAP CLI command vserver cifs session show will provide output on any sessions that utilize Continous Availability:

Example:

nas-cm910::> vserver cifs session show -fields continuously-available,windows-user,files
node         vserver  session-id          connection-id windows-user files continuously-available
