28 The \fBnscadm\fR command performs several network storage control functions.
31 The \fBnscadm\fR \fBfreeze\fR command closes existing references to the
32 specified device, and blocks future accesses. This allows maintenance of
33 virtual volume device drivers (for example, RAID 0, RAID 1, RAID 5) to be
34 performed without shutting down the system.
37 The \fBnscadm\fR \fBunfreeze\fR command reverses the effects of \fBnscadm\fR
38 \fBfreeze\fR for the specified device.
41 The \fBnscadm\fR \fBisfrozen\fR command returns the current status of the
