Hot swap allows a user to replace a failed drive in a redundant array while the system remains up. Hot swap can be used when 24x7 system operation is a consideration. If multiple drives are faulted in a RAID 10 configuration, you must rebuild the drives sequentially by port number starting with the lowest port number.
Click on the check box of the failed drive.
Click the Remove Drive button.
Physically remove the failed drive and replace it with a new drive.
Click on the check box of the new drive.
Click the Add Drive button.
Click on the check boxes of the members of the array to be rebuilt. This should include the new drive added in step 3.
Click the Rebuild Array button. The rebuild process will run in the background and an event notification will be sent when it is completed.
Selecting the Force Continue on Source Errors check box prior to rebuilding the array ensures rebuilds are not terminated if ECC errors are detected on the source disk. By default, this function is disabled.
