You cannot use cpcfg on a chassis platform.


Only on a chassis platform running 12.1.x or 13.0.x.


Save a UCS from the source volume, reboot to the destination volume, then load that UCS file.

Fix Information

cpcfg could incorrectly calculate the amount of free space available, refusing to do the copy unless the /shared filesystem had sufficient space to do the copy. This has been resolved and this free space calculation is done correctly.
