Enabling multi-connection sessions

By default, Data ONTAP is now configured to use a single TCP/IP connection for each iSCSI session. If you are using an initiator that has been qualified for multi-connection sessions, you can specify the maximum number of connections allowed for each session on the storage system.

About this task

The iscsi.max_connections_per_session option specifies the number of connections per session allowed by the storage system. You can specify between 1 and 32 connections, or you can accept the default value.

Note that this option specifies the maximum number of connections per session supported by the storage system. The initiator and storage system negotiate the actual number allowed for a session when the session is created; this is the smaller of the initiator’s maximum and the storage system’s maximum. The number of connections actually used also depends on how many connections the initiator establishes.

Steps

  1. Verify the current option setting by entering the following command on the system console: options iscsi.max_connections_per_session
    The current setting is displayed.
  2. If needed, change the number of connections allowed by entering the following command: options iscsi.max_connections_per_session [connections | use_system_default]

    connections is the maximum number of connections allowed for each session, from 1 to 32.

    use_system_default equals 1 for Data ONTAP 7.1, 16 for Data ONTAP 7.2 and subsequent maintenance releases, and 32 starting with Data ONTAP 7.3. The meaning of this default might change in later releases.
