Avago/LSI/MSM locate failed drive with storcli

First use the storcli binary to identify failed drives on each controller (sure, multiple instances of grep could be improved with regex)

./storcli /cALL/eALL/sALL show all|grep Failure|grep -vi predict

   Example output:

Status = Failure
/c0/e1/s5  Failure    46 -

  Start locating the failed drive:

./storcli /c0/e1/s5 start locate

  Example output:

CLI Version = 007.1017.0000.0000 May 10, 2019
Operating system = VMkernel 6.7.0
Controller = 0
Status = Success
Description = Start Drive Locate Succeeded.

   Stop locating the failed drive:

./storcli /c0/e1/s5 stop locate

  Example output:

CLI Version = 007.1017.0000.0000 May 10, 2019
Operating system = VMkernel 6.7.0
Controller = 0
Status = Success
Description = Stop Drive Locate Succeeded.

  To stop locate for all controllers, run the following command:

./storcli /cALL set activityforlocate=off
