       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.

       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.
