T-VOL
The areas which are already copied can be written as
usual.
If the host server tries to write data to the area which is
not copied yet, firstly ShadowImage for z/OS copies
that area from the S-VOL, and then the host server will
write data to the area after the copy operation
completes. Therefore, the result will be the same as
when the host server writes data to the area which is
already copied.
Cannot be written. Write processing
will finish abnormally.

remains dimmed when the total number of volumes defined in the storage
system is less than 1,024 volumes.
