Figure 4-5
Enable mirroring on the LSI adapter
6.
For both disks, change disk properties in the Mirrored Pair column.
The possible values are Primary, Secondary and Hot spare. Pressing the
Spacebar key marks one of the disks as Primary and the other as Secondary.
The physical disks in the internal drive bays are highlighted (SCSI ID 0 and 1).
7.
Exit the window by pressing Esc. No changes are made to the configuration
at this point.
8.
The following message appears:
Warning: Data on Secondary or Hot Spare! Mirroring will overwrite!
Confirm by pressing Enter and continue.
9.
Save the changes on the next window and exit the menu. The disks will
synchronize in the background.
Tip:
The option to mark the disk as hot spare is of no use on the x450.
Because of the physical limitation of the server (internal maximum of two
disks), it is not possible to add a hot spare disk to the mirrored volume
configuration anyway.
Note:
After confirming the mirror creation, the data on the secondary disk
is lost. The secondary disk will be overwritten by the content of the primary
disk whose content stays intact.
