Zhang,
 Thanks for your email.

DIX is supported in mpt3sas , but not by default and hence while loading
mpt3sas driver set module parameter "prot_mask=0x7F" to enable DIX
support.

Thanks,
 Chaitra

Subject: DIF/DIX in mpt3sas

Hi there,

Thanks for reading my email.

I am a Ph.D student of University of Minnesota, Twin Cities. Recently, I
am working on a project of T10 PI-capable MD module. However, I fail to
use DIX with the HBA/driver combination of LSI Logic / Symbios Logic
SAS3008 PCI-Express Fusion-MPT SAS-3 (rev 02) /mpt3sas even though I have
formatted the drives with DIF protection type 1. May I know if DIX (data
integrity extension) is supported in mpt3sas driver?

Thanks,
Baoquan Zhang--
