Command Line Interface Reference Guide
Tip: Partitions can be optionally created at the controller (controller paritioning) or at
the Windows OS through the disk administrator as host partitions.
After using this switch, information is written to the data area of the disk.
Note: Factory-shipped disks are typically partitioned. HP does not recommend
presenting new disks that are partitioned to a controller that is initially part of a
Windows-based system. Before adding new disks to a subsystem that presents units to
host systems that uses Windows operating systems, HP recommends that you add the
disk to the array and then issue the INITIALIZE
DISKxxxx command with the
DESTROY_MBR switch for all new factory-shipped disks and replacement spares. This
action eliminates the MBR block that is factory-written on new disk drives before they
are shipped from HP.
Failure to destroy the MBR block of new factory-shipped disks causes Windows to
create two single unallocated partitions. After issuance of this command and
presentation of the disk to a Windows host as a unit, the device is seen as a single
drive letter device.
If two disks are discovered (one being an 8-MB partition) after presenting a
new unit to a Windows host, use caution in identifying the correct disk
number to delete.
Enter the following command to initialize disk DISK031000 and destroy its
MBR partition:
INITIALIZE DISK031000 DESTROY_MBR
SAVE_CONFIGURATION
NOSAVE_CONFIGURATION (default)
Instructs the controller to save the controller configuration (or not to save the
configuration) to the container being initialized. If enabled, the
SAVE_CONFIGURATION switch, which is only supported on
single-controller configurations, saves a configuration to a disk or storageset.
The configuration can be retrieved later and downloaded onto a replacement
controller. It also retains code patches to the ACS software.
