I know, but if I understand it correctly, I need to not only disable a
particular path, I need to disable mpath support entirely to get
sg_write_buffer to talk to mpt_sas directly, instead of going through
the scsi_vhci glob in the middle (which, presumably, is what's causing
this problem). If I'm misunderstanding this, please do set me straight.
