Issue

  • Mistakenly ran: 
[root@host ~]# echo 1 > /sys/block/sda/device/delete
  • Realizing, attempted to recover by running: 
[root@host ~]# echo 0  > /sys/block/sda/device/delete
  • However, the device did not reappear in the /dev directory. How can I get it back?

Environment

  • Red Hat Enterprise Linux 6
