Suppressing update copy operations during pair restoration

You can suppress update copy operations when you restore pairs using Quick Restore. Suppressing
update copy operations keeps the P-VOL and S-VOL unsynchronized and reduces the effect on
host server I/O performance.

Prerequisite: The pair status is “PAIR”.

Enable the Swap & Freeze system option.

For more information about how to enable this system option, see

“Enabling system options”
