been created and in this group, the new pair has been created too. Refer
to the following example.
•
% aureplicationlocal –unit subsystem-name –ss –create –pvol 200
–svol 1001 –gno 20

(y/n[n]): y
The pair has been created successfully.

2. Add the name to the group if necessary using command to change the
pair information. Refer to the following example.
•
% aureplicationlocal –unit subsystem-name –ss –chg –gno 20 –pvol
200 –svol 1001
Are you sure you want to change pair information?
(y/n[n]): y
The pair information has been changed successfully.

3. Create the next pair that belongs to the created group specifying the
number of the created group with –gno option.
SnapShot pairs that share the same P-VOL must use same Data Pool.

can be created.
