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 re- ferred 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 Mean- ing" (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 sd- parm(8) man page. AUTHORS Written by D.
