NAME
       sas_disk_blink - blink the LED on a SAS disk


SYNOPSIS
       sas_disk_blink [--help] [--set NUM] [--verbose] DEVICE


DESCRIPTION
       This bash shell script attempts to blink the LED on the SAS disk referred to by DEVICE. By
       default the LED will blink for 30 seconds. This is  meant  to  help  identify  which  disk
       corresponds to a given DEVICE.

       The  script  use the sdparm utility and manipulates the "Ready LED Meaning" (RLM) field in
       the Protocol specific port mode page in order to blink the LED.


OPTIONS
       Arguments to long options are mandatory for short options as well.

       -h, --help
              print out the usage message then exit.

       -s, --set NUM
              when NUM is 0 then the RLM field is cleared. When NUM is 1 then the  RLM  field  is
              set.  When  NUM > 1 then the SAS disk LED is made to blink for NUM seconds. If this
              option is not given then the SAS disk LED is made to blink for 30 seconds.

       -v, --verbose
              increase level or verbosity.


EXIT STATUS
       The exit status of this script is 0 when it is successful. Otherwise the  exit  status  is
       that of the last sdparm utility called. See the sdparm(8) man page.
