Booting a System with a Backup RDR Boot Disk

1. Remove power from the system.
2. Remove all boot disks from the internal storage enclosure, if any are installed.
3. Insert the backup boot disk.
4. Press the system power button.

Reusing Data Disks

If you have stored a copy of a data disk that was created with RDR disk mirroring, use
the following procedures to reuse the disk in the system.

Reusing a Stored-Data Disk

After you perform this procedure:
•
The data on the stored-data disk is overwritten with the data on the disk in its
companion slot.
•
The stored-data disk remains an RDR disk.
To reuse a stored-data disk
1. Make sure the original partner of the stored disk is in the companion slot.
2. Insert the stored disk into its original slot. The system automatically resynchronizes
the stored disk with the partner disk.
Wait for the disk to be fully resynchronized before removing the stored disk or before
removing power from the system.

Removing the RDR Configuration from a Stored-Data Disk

This procedure removes the RDR configuration from a stored-data disk and deletes all
of its data.
