http://bugzilla.kernel.org/show_bug.cgi?id=13307 Summary: hotplug cascaded expander will cause unpluged devices not remove from os Product: SCSI Drivers Version: 2.5 Kernel Version: 2.6.29.2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: scsi_drivers-other@xxxxxxxxxxxxxxxxxxxx ReportedBy: jack_wang@xxxxxxxxx CC: linux-scsi@xxxxxxxxxxxxxxx Regression: No Hi,all We are developing a sas HBA driver based on libsas .when we hotplug cascaded expander will cause unpluged devices not remove from os.We look into the source code ,found that when BROADCAST CHANGES happend ,libsas will invoke sas_revalidate_domain to fonud out the change phy ,and it can found the right phy issue the BROADCAST CHANGE.But in sas_rediscover,it seems that it does nothing with the wide port case ,only print out a message.I submit this in case that it is real a bug.Any comments will be apprieciated. I send relevant output information of the dmesg attached with this mail.
