Setting The V-Vol; Setting The Lu Ownership - Hitachi AMS2100 User Manual

Setting the V-VOL

You can set a V-VOL or delete an existing SnapShot logical unit.
Prerequisites
• To create a SnapShot pair, you must first set up 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.
• When deleting the V-VOL, the pair state must be Simplex.
To set the V-VOL:
1. From the command prompt, register the array to which you want to set
the V-VOL, then connect to the array.
2. Execute the aureplicationvvol command create a V-VOL. For
example:
•
% aureplicationvvol –unit array-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.
%
3. To delete an existing SnapShot logical unit, refer to the following
example of deleting SnapShot logical unit 1000. When deleting the V-
VOL, the pair state must be Simplex.
•
% aureplicationvvol –unit array-name –rm -lu 1000
Are you sure you want to delete the SnapShot logical unit 1000?
(y/n[n]): y
The SnapShot logical unit has been successfully deleted.

Setting the LU ownership

The load balancing function is not applied to the LUs specified as a SnapShot
pair. Since the ownership of the LUs specified as a SnapShot pair is the same
as the ownership of the LUs specified as a data pool, perform the setting so
that the ownership of LUs specified as a data pool is balanced in advance.
To set LU ownership using CLI:
1. From the command prompt, register the array to which you want to set
the LU ownership, and then connect to the array.
2. Execute the autuningluown command to confirm an LU ownership.
