Hi Tom! I think you need to load ioctl module for qla4xxx called "qisioctl". The qlogic vendor driver includes this functionality "out of the box". Try here: ftp://ftp.qlogic.com/outgoing/linux/iSCSI/qisioctl/ Or here: ftp://ftp.qlogic.com/outgoing/linux/beta/iscsi/5.x/ -- Pasi _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
