Hi Javen,
Thanks for the info. Well my iSCSI driver
requires that i be able to rem_drv my driver with
tgts/luns attached ,i.e im wondering if the framework
internally provides options for the HBA driver to
detach its luns, i think i did see a print indicating
that tran_lun_reset_notify was called when i did
attempt to do it..so thats what im intersted to know
..is there a sequence to the rem_drv if/when
LUNs/Targets are attached to the SCSI HBA driver so
that i get a chance to remove all the child instances
of the driver from the device tree?
Thanks
Som
