[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: iscsi : default iscsi mode page settings.Does anyone know of where a Legacy function would exist, in the Host which would do anything with FirstBurstSize? I am assuming it would have to be in the SCSI Device Driver, and since we have iSCSI instead, that may not be an issue. I could be wrong but I do not think that it occures in the SCSI Class Drivers. And I do not think it ocures in the File Systems, so where does this Legacy function we are worried about occure? If it is in the SCSI Device Driver it is NOT an issue. . . . John L.

Anything iSCSI specific should attempt to follow other iSCSI methods of configuration (e.g. text keys). We should really be driving towards a single method of parameter negotiation and configuration - especially when the legacy methods have no clue about the new parameters and would require upgrades.
