sas_disk_blink - blink the LED on a SAS disk
sas_disk_blink [--help] [--set NUM] [--verbose] DEVICE
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.
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.
