Important:
Caution: If you do not use a multi-path driver, shut down any host applications that are currently using the array to prevent application errors when the I/O path changes.
Procedure for Logical Drives
To change controller ownership of a logical drive, select a logical drive in the Logical View; then, either select the Logical Drive >> Change Ownership pull-down menu option and select the controller from the sub-menu, or select Change Ownership from the right-mouse pop-up menu and select the controller from the sub-menu.
Result: The ownership of the logical drive is changed. I/O to the logical drive is now directed through this I/O path.
NOTE: The logical drive might not use the new I/O path until the multi-path driver reconfigures to recognize the new path. Typically, this takes less than five minutes.
Procedure for Arrays
To change controller ownership of an array, select an array in the Logical View; then, either select the Array >> Change Ownership pull-down menu option and select the controller from the sub-menu, or select Change Ownership from the right-mouse pop-up menu and select the controller from the sub-menu.
Important: Changing ownership at the array level causes every logical drive in that array to transfer to the other controller and use the new I/O path. If you do not want to set every logical drive to the new path, change ownership at the logical drive level instead.
Result: The ownership of the array is changed. I/O to the array is now directed through this I/O path.
NOTE: The array might not use the new I/O path until the multi-path driver reconfigures to recognize the new path. Typically, this takes less than five minutes.
