It keeps changing when iSCSI host is added and removed dynamically. This is a problem for persistent device naming for iSCSI devices through host id. It would be good to maintain a database of already allocated host id's for the existing hosts. This would render the iSCSI HBA to get the same controller id, irrespective of loading/unloading the driver repeatedly. Would like to know if there is any provision in 2.6 to achieve the above? thanks, surekha
