Enable and Disable iSCSI Optimization
The following describes enabling and disabling iSCSI optimizaiton.
NOTE
: iSCSI monitoring, auto-conguration and auto-detection is enabled by default.
If you enable iSCSI, ow control is automatically enabled on all interfaces. To disable ow control on all interfaces, use the no flow
control rx on tx off
command and save the conguration. To disable iSCSI optimization, which can turn on ow control again on
reboot, use the no iscsi enable command and save the conguration.
When you enable iSCSI on the switch, the following actions occur:
• Link-level ow control is enabled on interfaces where PFC is disabled.
• iSCSI session snooping is enabled.
• iSCSI LLDP monitoring starts to automatically detect EqualLogic arrays.
The following message displays when you enable iSCSI on a switch and describes the conguration changes that are automatically
performed:
%SYSTEM:CP %IFMGR-5-IFM_ISCSI_ENABLE: iSCSI has been enabled causing flow control to be enabled
on all interfaces. EQL detection and enabling iscsi profile-compellent on an interface may
cause some automatic configurations to
occur like jumbo frames on all ports and no storm control and spanning tree port-fast on the
port of detection.
You can recongure any of the auto-provisioned conguration settings that result when you enable iSCSI on a switch.
When you disable the iSCSI feature, iSCSI resources are released and the detection of EqualLogic arrays using LLDP is disabled. Disabling
iSCSI does not remove the MTU, ow control, portfast, or storm control conguration applied as a result of enabling iSCSI.
NOTE
: By default, CAM allocation for iSCSI is set to 0. This disables session monitoring.
