Keeping that in mind, a bus rescan is a better way to go (where a bus is 'virtual' for networked SCSI architectures). -prasenjit Prasenjit Sarkar Research Staff Member IBM Almaden Research San Jose Venkatesh Ramamurthy @vger.kernel.org on 01/18/2001 08:20:03 AM Sent by: linux-scsi-owner@vger.kernel.org To: "'Eric Youngdale'" , Douglas Gilbert , David Brownell cc: linux-scsi@vger.kernel.org, linux-hotplug-devel@lists.sourceforge.net Subject: RE: SCSI Patches - mostly on/off-line stuff > Anyways, my initial question reallly has to do with exactly how one is > notified that a new device has appeared and whether a bus scan needs to be > initiated or not.

I not sure whether all the scsi device do support it. If this the scsi case low level driver can call the SCSI ML to add the new device. I dont whether this is a general solution. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@vger.kernel.org _______________________________________________ Linux-hotplug-devel mailing list http://linux-hotplug.sourceforge.net Linux-hotplug-devel@lists.sourceforge.net http://lists.sourceforge.net/lists/listinfo/linux-hotplug-devel
