Setting the LU ownership

The load balancing function is not applied to the LUs specified as a TCE pair.
Since the ownership of the LUs specified as a TCE 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.
Perform the following steps to set LU ownership by 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 –unit array-name –refer
LU
1000
1001
2000
2001
%
The Core shows N/A: AMS2100/2300
3. Execute the
•
% autuningluown -unit array-name -set -lu 2001 -ctl0 -coreX
Are you sure you want to set the LU ownership? (y/n [n]): y
The LU ownership has been set successfully.

4. Execute the autuningluown command to confirm an LU ownership.
