Options for iSCSI sessions and error recovery levels

By default, Data ONTAP operating in 7-Mode enables four TCP/IP connections per iSCSI session and an error recovery level of 0.

In a 7-Mode environment only, you can optionally enable more than four connections per session and error recovery level 1 or 2 by setting Data ONTAP option values. For more information, see the information about managing the iSCSI network in the SAN Administration Guide for your version of Data ONTAP.

The iSCSI initiator does not automatically create multiple sessions. You must explicitly create each session using the iSCSI initiator GUI.

By default, clustered Data ONTAP enables a single connection per iSCSI session, and for E-Series storage systems, SANtricity Storage Manager enables a single connection per iSCSI session.
