Procedures to Replace Failed Disks
1.3.2
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 refresh RDR Utility status frequently right 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)
When the disk is physically formatted and recycled, the inserted disk might be
automatically set to RDR.
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
>.
Here, an example that a failure of the disk in slot 1 of the PCI module 10 is explained.
1. Click
Start
–
RDR
–
RDR Utility
to start RDR Utility.
2. Remove the disk in the slot 1 of the PCI module 10.
3. Wait for at least 15 seconds, and insert a new disk to the slot 1 of the PCI module 10.
If a popup window asking for rebooting the system is displayed, select
Restart Later
and close the
popup window.
