Mirroring Windows Server 2. GBT and MBR Boot and System Disks. Previous. Table of Contents.

An Overview of GPT and MBR Partition Styles. Before a Windows Server 2008 system disk can be mirrored it is important to identify the partition style used by the disk. GPT is a modern partition table. Contrary NTFS is a filesystem, which is different from a partition table. Windows 7 needs the old MSDOS partition table and a. Understanding MBR Disks. With MBR the first sector of the disk is reserved to store a partition table and the master boot record. The remainder of the disk is divided. If you discover that Windows 8 isn't quite your cup of tea, and you have no feasible path to downgrade, it may be a good idea to dual boot with Linux to have an.

It is important to note that the steps necessary for mirroring system disks differs depending on whether the disk uses the MBR or GPT partitioning style.

As such, this chapter will cover the steps necessary to mirror both types of Windows Server 2. In order for a disk to be used to store data it must first have partitions created on it. These partitions are then formatted with a particular file system (FAT, FAT3. NTFS) and used either as a basic disk or as dynamic disk. Obviously, the operating system needs some mechanism for organizing and managing these disk partitions and Windows Server 2.

Master Boot Record (MBR) or GUID Partition Table (GPT). GPT, on the other hand, was originally developed for 6. Itanium based systems. With the arrival of Windows Server 2. MBR and GPT partition styles.

It is important to note, however, that 3. MBR disk partitions and 6. GPT partitions. Of most significance is the fact that the two partition styles have very different configurations in terms of special mandatory partitions required in order to store data. In addition, other mandatory partitions are required on each disk style in order to operate as boot and system disks. In terms of MBR disks a master boot record (MBR) partition is required.

On GPT disks, EFI system (ESP) and Microsoft Reserved (MSR) partitions must be present in order for the disk to be bootable. It is important, therefore, that these partitions are created as part of the system disk mirroring configuration process. For the purposes of this chapter we will be working with a system containing two disk drives. Disk 0 is the system disk and disk 1 is an unallocated disk installed for the purpose of mirroring the system disk. This process can be performed using either the Disk Management interface or from the command prompt using the diskpart tool (covered in the next section).

The Disk Management interface can be accessed either from the Server Manager or Computer Management tools. To launch the Server Manager, open the Start menu and click on the Server Manager option, or click on the Server Manager icon in the task bar. Alternatively launch Computer Management from Start - > All Programs - > Administration Tools - > Computer Management or run compmgmt. Run dialog. To achieve this right click on the system drive in the Disk Management graphical view, select Convert to Dynamic Disk.. To achieve this right click on the system volume in the Disk Management graphical view and select Add Mirror.. The resulting Add Mirror dialog will list the disk drives available on the system. Select the desired disk (in this case disk 1) as shown below.

With a suitable mirror disk selected, click on Add Mirror to begin the resynching process. During this phase the operating system will copy all the files from the original system volume (including System, Boot, Page.

File and Crash Dump) to the mirror disk. It will also create the master boot record (MBR). Finally, Windows will add the mirror as a secondary boot option in the Boot Manager such that it can be selected when the system is rebooted.

During the reboot process the boot menu will appear listing the shadow system partition as Microsoft Windows Server 2. WIN2. 8BOX< /google>. Mirroring Boot and System Volumes on an MBR Disk from the Command Prompt. The system and boot volumes on an MBR disk may also be mirrored from the command prompt using the diskpart tool. Begin by listing the disks attached to the system using the diskpart list disk command. DISKPART> list disk. Disk ### Status Size Free Dyn Gpt.

Disk 0 Online 3. GB 1. 5 GB *. * Disk 1 Online 1.

GB 1. 7 GB *. In the above output disk 0 is the current system disk and disk 1 is the disk to be used as the shadow system disk. If the disks are not yet dynamic they need to be converted before the remainder of the mirroring set up and can be completed. DISKPART> select disk 0. Disk 0 is now the selected disk. To obtain a list of volumes, select the disk and use the list volume command. DISKPART> list volume.

Volume ### Ltr Label Fs Type Size Status Info. Volume 0 C NTFS Simple 1. GB Healthy System. Volume 1 D DVD- ROM 0 B No Media. In the above example the system volume is listed as Volume 0. To mirror this volume, select the volume and then add disk 1 as a mirror using the add disk= command.

DISKPART> select volume 0. Volume 0 is the selected volume. When a list volume command is run during this process, the volume status will be listed as Rebuild until the resynching is complete. DISKPART> list volume. Volume ### Ltr Label Fs Type Size Status Info. Volume 0 C NTFS Mirror 1. GB Rebuild System.

Volume 1 D DVD- ROM 0 B No Media. When the Status changes to Healthy the mirroring is complete. Next time the system is rebooted the mirror will be listed in the boot menu as Microsoft Windows Server 2. For the purposes of this tutorial we will be working with a system containing a GPT system disk and a new disk numbered as disks 0 and 1 respectively. The objective will be to mirror the GTP system disk on disk 1.

Once started, diskpart will present the DISKPART> prompt where commands may be entered. Before disk 1 can be used, any existing partitions on that disk must be removed. To identify any current partitions, select this disk and list partitions as follows. DISKPART> list partition. Partition ### Type Size Offset. Partition 1 Primary 1. GB 1. 02. 4 KB. Clearly, this disk already contains a partition.

If this data is required, be sure to back it up before removing any partitions. Once the backup is complete, select and delete any partitions as follows. DISKPART> select partition 1.

Partition 1 is now the selected partition. Since the disk no longer contains any partitions this can be now be achieved using the convert command.

DISKPART> convert GPT. Disk. Part successfully converted the selected disk to GPT format. To do so select the system disk and list the partitions. DISKPART> select disk 0. DISKPART> list partition. Partition ### Type Size Offset. Partition 1 System 3.

MB 3. 2 KB. Partition 2 Primary 1. MB 3. 04 MB. Partition 3 Reserved 3. MB 1. 3 GB. In the above output, Partitions 1 and 3 are the EFI and MSR partitions respectively. In order to accurately mirror the system disk these partitions also need to created on the mirror disk using the create partition command and the efi and msr options as follows. DISKPART> select disk 1.

Disk 1 is now the selected disk. Before this can be achieved, the partitions need to be assigned drive letters. DISKPART> select disk 1. Disk 1 is now the selected disk. Note that it may be necessary to launch the command prompt with elevated privileges. To do this, locate the command prompt in the Start menu, right click on it and select Run as Administrator. Once the disks are converted to dynamic disks the final stage in the process is to add disk 1 as the mirror for the system disk.

Once again start up diskpart and execute the following commands. DISKPART> select disk 0.

Disk 0 is now the selected disk. DISKPART> select volume C. Volume 0 is the selected volume. In addition to resynching the mirrored volumes Windows will also add the mirrored disk to the boot configuration such that it will be listed as the Microsoft Windows Server 2.
