Procedures to Replace Failed Disks
This section describes a procedure for replacing a disk when a failure occurs to a disk that is duplexed by the
RDR function.
Important

Do not update RDR Utility frequently immediately after inserting a disk.

For a disk to be inserted, use a new or physically formatted disk which has the
same capacity as the disk of the corresponding slot (in this example, the disk in
slot 1 of the PCI module 10)
Tips

The display of RDR Utility is not updated automatically. Therefore, update it every time
you check the status of disks by clicking Refresh from Action on the menu or pressing
< F5 >.

When the disk is physically formatted and recycled, the inserted disk might be
automatically set to RDR.
Here, an example that a failure of the disk in slot 1 of the PCI module 10 is explained.
