Encled - utility to change location / fault LED for enclosure.
I'm not sure if it works with every avaible enclosures, but at least it
works with Supermicro chases with SAS enclosures (LSI).
Encled heavily depends on linux kernel's /sys/class/enclosure
Previous name was sdled, but now it supports not only 'sd' devices
but empty disk slots too.
Usage:
encled (without options) - display all slots devices status and disk letter
encled enclosure/slot - display status of requested device
encled enclosure/slot fault - set led indicator to 'faulty'
this WILL NOT make device faulty, just set
enclosure led to 'FAULTY' status.
encled enclosure/slot locate - set led indicator to 'locate' status
encled enclosure/slot off - turn of faulty/locate status
encled device locate/fault/off will work with sd device (sda, sde)
encled ALL off
encled ALL fault
encled ALL locate - turn all devices to that status (note CAPS ALL)
examples:
encled 4:0:1:0/12 - show status for enclosure 4:0:1:0 slot 12
encled ALL off - disable all indication for all slots in all enclosures
encled 5:0:24:0/24 fault - set fault indicator for enclosure 5:0:24:0 slot 24
encled 5:0:24:0/12 locate - set location indicator for enclosure 5:0:24:0 slot 12
encled sda locate - enable 'locate' for slot with sda block device
encled /dev/sdbz fault - enable fault indicator slot with sdbz block device
