The microcode is restored to its previous state

DISK ERROR
When a disk error occurs during an upgrade, the
MCF function is canceled. The next time you re-
enter the MCF function, the MCFs applied during
the canceled function will be restored to their pre-
vious levels.
There is no roll-back in this case, since it is not a
logical error but a hardware error, which must be
corrected before anything else.
