Rescan sata port (hot-swap)

Short:

First: identify and delete the old drive (identify HCTL, which is Host:Channel:Target:Lun (viz ))

$ lsscsi

$ lsblk -o NAME,MODEL,HCTL

and also:

readlink /sys/block/sdX

To find the physical SATA port number, add one to the given host number.

2:0:0:0 -> H=2, sdb == ata3

Or use this command:

# find -L /sys/bus/pci/devices/*/ata*/host*/target* -maxdepth 3 -name "sd*" 2>/dev/null |\
egrep block |egrep --colour '(ata[0-9]*)|(sd.*)'

/sys/bus/pci/devices/0000:00:18.0/ata1/host0/target0:0:0/0:0:0:0/block/sda
/sys/bus/pci/devices/0000:00:18.0/ata2/host1/target1:0:0/1:0:0:0/block/sdb
/sys/bus/pci/devices/0000:00:18.0/ata3/host2/target2:0:0/2:0:0:0/block/sdc
  ...   

As a first step, the old drive has to be deleted (see), and (see):

echo 1 > /sys/block/sda/device/delete

Then rescan the host bus:

echo "- - -" >/sys/class/scsi_host/host<n>/scan

or

for i in /sys/class/scsi_host/host* ; do echo "- - -" > $i/scan ; done
