Hot-add Hot-remove: linux scsi subsystem
We've got erroneous scsi entry, remove it:for n in `seq 0 0`; do echo $n; echo "scsi remove-single-device 1 0 0 $n" > /proc/scsi/scsi ; echo "scsi remove-single-device 0 0 0 $n" > /proc/scsi/scsi ; doneNow, we attached new FC LUN as 0:0:0:0 and 1:0:0:0
for n in `seq 0 0`; do echo $n; echo "scsi add-single-device 1 0 0 $n" > /proc/scsi/scsi ; echo "scsi add-single-device 0 0 0 $n" > /proc/scsi/scsi ; donenow, multipath -ll will show you, that multipath deteceted deviced with extra path to it, and created new device for it:
