bnx2 modules or running ifdown on the network interface being used by bnx2i driver will result in the iSCSI sessions being disconnected. Reloading the module or running ifup, will not reconnect the SCSI sessions. To work around this issue, the iscsi service must be stopped and then restarted. (BZ#514926)
