Using RDR for Fault Tolerance

Disk Storage Management 4-9

NOTE

If you receive an error message when using the Add

Physical Disk To RDR Virtual Disk command, the disk

you are trying to add may not have sufficient free space for

the metadata. Be sure the disk has a minimum of 10MB

free space.

A System Shutdown message may appear, stating that the system will reboot in two

minutes. If the message appears, let the system restart.

NOTES

1. If you have added a system disk to an RDR virtual

disk, a message notifies you that the system will

reboot. The message gives you the option of

confirming or cancelling the request. The system also

restarts if you add a data disk to an RDR virtual disk

and the software cannot unmount all data volumes on

the disk.

2. You cannot add a physical disk to RDR if the disk is

dynamic or a nonblank data disk.

5. In the Device Configuration Change dialog box, click Yes.

6. Repeat steps 3–5 for the corresponding disk in I/O element 11.

For example, expand ftServer I/O Enclosures, I/O Enclosure - 11,

Storage Enclosure - 40, Slot - 1, and then click Disk - 0.

7. Allow time for the two disks to synchronize.

• While the disks are resynchronizing, LEDs blink to indicate read and write

operations and ftSMC displays a value of OpState: State Syncing in the details

pane for the disk.

To view the progress of the synchronization in ftSMC, expand Logical Disk

Information under ftServer I/O Enclosures, and select the virtual disk (for

example, RDR Virtual Disk 1). In the details pane, the progress is noted as a

percentage, as follows:

Status: Resync: 20 percent

When the disks are synchronized, the LEDs on both disks are lit steady green

and ftSMC displays a value of OpState: State: Duplex in the details pane for

the disk and for the virtual disk. The value next to Status for the virtual disk is

None.
