From dc293f60b02ff9a4d51ccae153b1685cc8a34d79 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 9 Mar 2021 14:56:42 +0100 Subject: [PATCH] scsi: fix sense code for EREMOTEIO MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit SENSE_CODE(LUN_COMM_FAILURE) has an ABORTED COMMAND sense key, so it results in a retry in Linux. To ensure that EREMOTEIO is forwarded to the guest, use a HARDWARE ERROR sense key instead. Note that the code before commit d7a84021d was incorrect because it used HARDWARE_ERROR as a SCSI status, not as a sense key.
