Perhaps someone from >> LSI/Avago/Broadcom could supply more information about that. Indeed, mpt3sas has internal enclosure some how. snip from "sas3ircu 0 display" output: Device is a Hard disk Enclosure # : 1 Slot # : 4 SAS Address : 4433221-1-0400-0000 State : Ready (RDY) And it's possible to locate it using "sas3ircu 0 locate 1:4 ON" to locate the drive.
