3. Execute the aupool command to verify that the Data Pool has been
created. Refer to the following example.
4. When deleting the logical unit set as the Data Pool, it is necessary to
delete all Snapshot images (V-VOLs). To delete an existing Data Pool,
refer to the following example.
5. To change an existing threshold value for a Data Pool, refer to the
following example.
Setting the V-VOL
To create a SnapShot pair you must first set a V-VOL.
If a specification for the logical unit assigned to a V-VOL is omitted when
setting the V-VOL, Navigator 2 assigns the smallest undefined number to
the logical unit.
To set the V-VOL:
1. From the command prompt, register the subsystem to which you want
to set the V-VOL, then connect to the subsystem.
2. Execute the aureplicationvvol command create a V-VOL. For
example:
% aupool –unit subsystem-name –refer -poolno 0
Data Pool : 0
Data Pool Usage Rate: 6% (2.0/30.0 GB)
Threshold : 70%
Status : Normal
LUN Capacity RAID Group RAID Level Type Status
100 30.0GB 0 6( 9D+2P) SAS Normal
%
% aupool –unit subsystem-name –rm -poolno 0
Are you sure you want to delete all logical units from the data
pool 0?
(y/n[n]): y
The logical units have been successfully deleted.
%
% aupool –unit subsystem-name –cng -poolno 0 -thres 70
Are you sure you want to change the threshold of usage rate in
the data pool?
(y/n[n]): y
The threshold of the data pool usage rate has been successfully
changed.
%
% aureplicationvvol –unit subsystem-name –add –lu 1000 –size 1
Are you sure you want to create the SnapShot logical unit 1000?
(y/n[n]): y
The SnapShot logical unit has been successfully created.
