Description
The reverse resync
operation on the pair
has been accepted
normally. The reverse
resyn operation is
1
executed. When a
split pair is reverse
resynchronized, the XP
storage system copies
only the T-VOL
differential data to the
S-VOL. The reverse
copy cannot be
performed on
suspended pairs. No
update copy
operations are
performed during
reverse copy or quick
restore.
The XP storage system
does not perform
update copy
operations to a
suspended T-VOL. The
storage system marks
the entire S-VOL track
map as differential
data, so the entire
S-VOL is copied to the
T-VOL when the pair
is resumed. Use resync
command to resume a
suspended pair.
Reverse copy and
quick restore cannot
be used to resume
suspended pairs.
