sas_disk_blink
SAS_DISK_BLINK(8) SDPARM SAS_DISK_BLINK(8) 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. AUTHORS
