Added a store functionality to set rport port_state using sysfs under fc_remote_ports/rport-*/port_state With this functionality the user can move the port_state from Marginal -> Online and Online->Marginal. On Marginal :This interface will set SCMD_NORETRIES_ABORT bit in scmd->state for all the pending io's on the scsi device associated with target port. On Online :This interface will clear SCMD_NORETRIES_ABORT bit in scmd->state for all the pending io's on the scsi device associated with target port. Below is the interface provided to set the port state to Marginal and Online. echo "Marginal" >> /sys/class/fc_remote_ports/rport-X\:Y-Z/port_state echo "Online" >> /sys/class/fc_remote_ports/rport-X\:Y-Z/port_state Signed-off-by: Muneendra <muneendra.kumar@xxxxxxxxxxxx> --- v7: No change v6: No change v5: No change v4: Addressed the error reported by kernel test robot Removed the code needed to traverse all the devices under rport to set/clear SCMD_NORETRIES_ABORT Removed unncessary comments. Return the error values on failure while setting the port_state v3: Removed the port_state from starget attributes. Enabled the store functionality for port_state under remote port. used the starget_for_each_device to traverse around all the devices under rport v2: Changed from a noretries_abort attribute under fc_transport/target*/ to port_state for changing the port_state to a marginal state --- drivers/scsi/scsi_transport_fc.c | 56 ++++++++++++++++++++++++++++++-- 1 file changed, 54 insertions(+), 2 deletions(-)
