3Select Change→ Copy Priority.

The Change Copy Priority window is displayed.

4In the Copy Priority area, select the appropriate copy priority, depending on your system performance needs.

NOTE: There are 5 copy priority rates available: lowest, low, medium, high, and highest. If the copy priority is set at the lowest rate, I/O activity is prioritized, and the virtual disk copy takes longer.

Stopping a Virtual Disk Copy

You can stop a virtual disk copy operation that has an In Progress status, a Pending status, or a Failed status. Stopping a virtual disk copy that has a Failed status clears the Needs Attention status displayed for the storage array.

Keep these guidelines in mind when you stop a virtual disk copy:

•To use this option, select only one copy pair in the Copy Manager.

•When the virtual disk copy is stopped, all of the mapped hosts have write access to the source virtual disk. If data is written to the source virtual disk, the data on the target virtual disk no longer matches the data on the source virtual disk.

To stop a virtual disk copy, complete the following steps:

1In the AMW, select Virtual Disk→ Copy→ Copy Manager. The Copy Manager window is displayed.

2Select the copy pair in the table.

3Select Copy→ Stop.

4Click Yes.
