Noob question - What is sd(8,3)

Submitted by Anonymous
on February 25, 2007 - 2:00pm

Had a power outage this morning, and noticed the following snippet in dmesg. I'm not sure which hard drive or partition it's referring to as sd(8,3). Any help would be greatly appreciated.

Sections below include
* snippet
* mount
* /proc/scsi/scsi
* dmesg

----- Snippet -----

Thanks, I wasn't aware of that file. :(

Pretty clear to me now from that file that sd(8,3) refers to sda3.

Thanks for the very quick response!
