Detection and Port Configuration for Dell Compellent Arrays

Switches support the

storage array. The command configures a port for the best iSCSI traffic conditions and must be entered in

INTERFACE Configuration mode.

The following message is displayed the first time you use the

configure a port connected to a Dell Compellent storage array and describes the configuration changes that

are automatically performed:

%STKUNIT0-M:CP %IFMGR-5-IFM_ISCSI_AUTO_CONFIG: This switch is being configured for optimal

conditions to support iSCSI traffic which will cause some automatic configuration to occur

including jumbo frames and flow-control on all ports; no storm control and spanning-tree port

fast to be enabled on the port of detection.

After you execute the

Jumbo frame size is set to 12000 for all interfaces on all ports and port-channels, if it is not already

Spanning-tree portfast is enabled on the interface.

Unicast storm control is disabled on the interface.

You must enter the

Synchronizing iSCSI Sessions Learned on VLT-Lags with

The following behavior occurs during synchronization of iSCSI sessions:

If the iSCSI login request packet is received on a port belonging to a VLT lag, the information is

synced to the VLT peer and the connection is associated with this interface.

Additional updates to connections (including aging updates) that are learnt on VLT lag members are

synced to the peer.

When receiving an iSCSI login request on a non-VLT interface followed by a response from a VLT

interface, the session is not synced since it is initially learnt on a non-VL T interface through the request

A new connection log is generated by the peer that sees the login response packet. If the login response

packet uses the ICL path, it will be seen by both the peers, which in turn generate logs for this
