.SH WARNINGS
.sp
.LP
\fBiicpshd\fR should be run only when the system is in single-user mode. When
you run \fBiicpshd\fR, the command makes no attempt to check if a Point-in-Time
set is in use. Running \fBiicpshd\fR with the \fB-s\fR flag while Point-in-Time
is using the old shadow volume can result in shadow volume data loss. If you
use the \fB-s\fR option, you must manually copy the data on the old shadow
volume to the new shadow volume.
