So what's happening here is the firmware is detecting a Xfer-ready from the storage when in fact the data-direction for a mode-select should be a write (DATA_OUT). The following patch fixes the problem (typo). Verified by Brian, as well. diff --git a/drivers/md/dm-mpath-rdac.c b/drivers/md/dm-mpath-rdac.c index 8b776b8..16b1613 100644 --- a/drivers/md/dm-mpath-rdac.c +++ b/drivers/md/dm-mpath-rdac.c @@ -292,7 +292,7 @@ static struct request *get_rdac_req(struct rdac_handler *h, rq->end_io_data = h; rq->timeout = h->timeout; rq->cmd_type = REQ_TYPE_BLOCK_PC; - rq->cmd_flags = REQ_FAILFAST | REQ_NOMERGE; + rq->cmd_flags |= REQ_FAILFAST | REQ_NOMERGE; return rq; } -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
