    # echo '- - -' > /sys/class/scsi_host/<host#>/scan
  3. Rescan all SCSI block devices associated with the volume group
    # echo 1 > /sys/block/<block device>/device/rescan
  4. Resize all physical volumes associated with the volume group
    # pvscan
    # pvresize /dev/<block device>
  5. Activate the volume group's logical volumes
