How to Make SCSI Enclosure LED’s Blink



# yum install sg3_utils

It depends on your particular backplane being visible to the host system (it should be visible as SCSI device under lsscsi -g).

In general, to turn on ID LED in a slot 1 of the /dev/sg4 enclosure you should invoke a command

# sg_ses --dsn=1 --set=ident /dev/sg4

and to Turn it off

# sg_ses --dsn=1 --clear=ident /dev/sg4
