You must enter the iscsi profile-compellent command in INTERFACE configuration mode. For example:
FTOS(conf-if-te-o/50# iscsi profile-compellent
Auto-detection of Dell Compellent
To auto-detect iSCSI optimization on a switch connected to a Dell Compellent array,:
Enabling and Disabling iSCSI Optimization
If iSCSI is enabled, flow control will be automatically enabled on all interfaces. To disable the flow control
on all interfaces, enter the command “no flow control rx on tx off” and save the configuration. To disable
iSCSI optimization, which can turn on flow control again on reboot, enter the command “no iscsi enable”
and save the configuration.
When you enable iSCSI on the switch, the following actions occur:
• Link-level flow control is globally enabled, if it is not already enabled, and PFC is disabled.
• iSCSI LLDP monitoring starts to automatically detect EqualLogic arrays.
The following message is displayed when you enable iSCSI on a switch and describes the configuration
changes that are automatically performed:
%STKUNIT0-M: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 reconfigure any of the auto-provisioned configuration 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, flow control, portfast, or storm
control configuration applied as a result of enabling iSCSI.
