Warnings

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