PRIMEQUEST System Disk Mirror for Windows User's Guide V1.0

3.1.1 Preparing for Disk Swap (Removing Disks)

Before exchanging disks, remove disks to be replaced from PSDM management.

To perform the preparatory procedures (to remove disks) for disk swap, you must be a user with administrator privileges (a user of the Administrators group).

1. Setting boot control

   If a disk is removed, the system is rebooted automatically. Because it is required to turn off the power to the PRIMEQUEST partition during disk swapping, configure the setting to prevent Windows automatic startup on system reboot.

   The procedure below explains how to configure this setting.

   1. Open [Partition]-[Partition#x]-[Boot Control] on the MMB Web-UI. Where #x is the PRIMEQUEST partition number.
      

   2. Select [Force boot into EFI Boot Manager] from the [Boot Selector] pull-down menu and click [Apply].

   
   

2. Opening the command prompt

   Select [start]-[All Programs]-[Accessories]-[Command Prompt] to open Command Prompt.

   
   

3. Checking the disk to be replaced

   Check the disk name, status, mirror group name, and location of the disk to be replaced.

   For faulty disks, the STATUS field shows "ERROR."

   Example: The disk number of the disk to be replaced is 1, the disk name is Disk1, the status is ERROR, the mirror group name is Group0, and the location is IOU#0-HDD#1.

   > sdxinfo -D
   OBJ  NAME   TYPE   GROUP   DEVNAM DEVBLKS      STATUS
   ---- ------ ------ ------- ------ ------------ -------
   disk Disk0  mirror Group0  0          35291136 VALID
   disk Disk1  mirror Group0  1          35291136 ERROR

   > sdxinfo -P
   OBJ    NAME BLOCKS       STATUS  DKNAME LOCATION
   ------ ---- ------------ ------- ------ ---------------------------------------
   device 0        35291136 VALID   Disk0  IOU#0-HDD#0
   device 1        35291136 ERROR   Disk1  IOU#0-HDD#1

   
   For details on the sdxinfo command, see "sdxinfo - Disk configuration and status viewing."

   

   • If only one VALID disk exists in the mirror group, it is not possible to replace only the VALID disk with another. Disks other than the VALID disk must be swapped first.
     

   • If no disk in VALID status exists in the mirror group, the procedures described in this section are not applicable. In this event, remove the mirroring once and then perform disk swap.

   
   

4. Removing the disk

   Remove the disk to be replaced from PSDM management.

   Responding to the message "Do you want to proceed(yes/no)?," type "yes" and press the Enter key. If the command ends normally, system reboot will commence automatically.

   Example: The disk Disk1 is swapped.

   > sdxsysdisk -R -d Disk1
   SDX: sdxsysdisk: 64206: INFO: After execution of this command, the system will reboot automatically. Do you want to proceed (yes/no)? yes

   
   

   
   For details on the sdxsysdisk command, see "sdxsysdisk - Mirroring and unmirroring."

   
   

5. Stopping the system

   When the EFI Boot Manager menu is displayed and the input mode is entered, turn off the power to the PRIMEQUEST partition.

   EFI Boot Manager ver 1.xx [xx.xx]

   If Windows automatic startup occurred, shut down Windows before turning off the power to the PRIMEQUEST partition.
