[PATCH 1/3] mpt2sas: Return the correct sense key for DIF errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Martin K. Petersen" <martin.petersen@xxxxxxxxxx>

Only a target device should return ABORTED COMMAND when a PI error is
discovered. The HBA should always set the sense key to ILLEGAL REQUEST.
