Increasing the iSCSI session error recovery level enables you to receive more detailed information about iSCSI error recoveries. Using a higher error recovery level might cause a minor reduction in iSCSI session performance.

About this task

By default, ONTAP is configured to use error recovery level 0 for iSCSI sessions. If you are using an initiator that has been qualified for error recovery level 1 or 2, you can choose to increase the error recovery level. The modified session error recovery level affects only the newly created sessions and does not affect existing sessions.

Beginning with ONTAP 9.4, the max-error-recovery-level option is not supported in the iscsi show and iscsi modify commands.

Steps

  1. Enter advanced mode:

    set -privilege advanced

  2. Verify the current setting by using the iscsi show command.

    iscsi show -vserver vs3 -fields max-error-recovery-level

    vserver max-error-recovery-level
------- ------------------------
vs3     0

  3. Change the error recovery level by using the iscsi modify command.

    iscsi modify -vserver vs3 -max-error-recovery-level 2
