-w or -W wouldn't be too bad an alternative (_w_rite cache). > We also have a scsi(8) tool that seems more analogous to atactl (which > can manipulate cache behavior). scsi(8) can manipulate write cache on some drives too. But in this case we're talking about a setting for the volume rather than for drives, so bioctl(8) wouldn't be a bad choice. (I don't know about mpii, but for mpi the vendor management tool in some OS allows you to set this, and bioctl is the closest analogue to this).
