Note: The initial mirror synchronization can take up to several hours. The process itself runs in the background. You can begin the operating system installation at any time, even while the synchronization is running. During the synchronization, the server may be restarted or turned off as needed. If not finished, the procedure will continue after restarting without user intervention. 10.The following message appears: Drv[dd] Ctrl[cc] Lang[eng] - Options set. Action Required is Stop Controller Press Enter to stop the controller. 11.Enter the command connect dd, where dd is the previously used the LSI driver handle to restart the controller. In our example, the command would be connect 50. Note: Actions described in steps 10 and 11 do not affect the progress of the mirror synchronization. Deleting the disk content There are situations when it is necessary to delete the contents of the disk. For example, you want to install an operating system on a disk that was previously used in a non-EFI system (that is, with a disk with a standard Master Boot Record (MBR), or you want to delete a partition that is reserved and cannot be deleted by other means (for example, a Microsoft Reserved Partition - see "Microsoft Reserved Partition" on page 88). Tip: If you need to perform a low-level format of the disk, use the LSI Configuration utility, which was described in "Configuring SCSI controller and internal disks" on page 74. To delete the content of the disk, perform the following steps: 1. Download the DISKPART.EFI drive partitioning utility. Transfer it to the x450 using a device such as a USB memory key or CD-R.

Deleting the disk content
There are situations when it is necessary to delete the contents of the disk. For
example, you want to install an operating system on a disk that was previously
used in a non-EFI system (that is, with a disk with a standard Master Boot
Record (MBR), or you want to delete a partition that is reserved and cannot be
deleted by other means (for example, a Microsoft Reserved Partition — see
“Microsoft Reserved Partition” on page 88).
To delete the content of the disk, perform the following steps:
1.
Download the DISKPART.EFI drive partitioning utility. Transfer it to the x450
using a device such as a USB memory key or CD-R. This is available from:
Note:
The initial mirror synchronization can take up to several hours. The
process itself runs in the background. You can begin the operating system
installation at any time, even while the synchronization is running.
During the synchronization, the server may be restarted or turned off as
needed. If not finished, the procedure will continue after restarting without
user intervention.
Note:
Actions described in steps 10 and 11 do not affect the progress of
the mirror synchronization.
Tip:
If you need to perform a low-level format of the disk, use the LSI
Configuration utility, which was described in “Configuring SCSI controller and
internal disks” on page 74.
