LSI sense codes
Posted by jpluimers on 2016/04/29
A while ago, I had RAID arrays suddenly drop out with unexpected sense codes.
I had a hard time tracking down what was wrong (it ended up being a faulty LSI Multi-lane Internal SFF-8087 to SATA/SAS Cable).
This caused all sorts of unexpected failures, hard to track down to any specific sense code.
As drives are bound to fail, and finding sense codes is a bit difficult, here are a few links that might help if I ever run into trouble again:
- Each sense codes is actually a Key Code Qualifier – Wikipedia, the free encyclopedia.

This sense (b/00/00: Aborted Command – no additional sense code) gave Matthijs ter Woord the idea the cable might be at fault:
04/19/15 8:14:35: EVT#4602644-04/19/15 8:14:35: 113=Unexpected sense: PD 0a(e0xfc/s1) Path 4433221102000000, CDB: 2f 00 00 0f f2 6d 00 10 00 00, Sense: b/00/00
Other sense codes I had:
- 6/29/00: Unit Attention – POR or device reset occurred
- 5/24/00: Illegal Request – invalid field in CDB (Command Descriptor Block)
Note that some Dell PERC controllers are OEM LSI megaRAID controllers. Same for some IBM (including the M1015)
Note not all drives are LSI megaRAID compatible, especially not this SSD:
