Storage Management supports virtual disk creation on 4KB sector hard-disk drives connected to PERC 9
hardware controllers.
NOTE: 4KB sector hard-disk drives are not supported on controllers prior to PERC 9 family of
hardware controllers. If the 4KB sector hard-disk drive is connected to any hardware controller prior
to PERC 9, the 4KB sector hard-disk drive is displayed as Unsupported.
• When you create a virtual disk using the Advanced Wizard, you can select the physical disk sector
from the Sector Size drop-down list. The options available are:
– 512B
– 4KB
• You cannot use both 4KB sector hard-disk drives and 512B sector hard-disk drives for a virtual disk
creation as mixing of hard-disk drive sectors is not allowed in Storage Management.
NOTE: If the system contains any 512e sector hard-disk drives, the 512e sector hard-disk drives
are identified/reported as 512B sector hard-disk drives and follows the behavior of the 512B
sector hard-disk drives.
Hot Spare Considerations — 4KBSector Hard-Disk Drives
The following is the Hot Spare considerations (Dedicated and Global Hot Spare) for 4KB sector hard-disk
drives supported on PERC 9 hardware controllers:
• You cannot assign 4KB sector hard-disk drives as Dedicated Hot Spare for virtual disks created with
512B sector hard-disk drives and vice versa.
• You cannot assign 4KB sector hard-disk drives as Global Hot Spare, if the virtual disk created consists
of 512B sector hard-disk drives only and vice versa.
• You can assign 4KB sector hard-disk drives as Global Hot Spare, if there are 4KB sector hard-disk
drives and 512B sector hard-disk drives in the virtual disks created and vice versa.
NOTE: If you perform this action a warning message is displayed.

Reconfiguration Considerations — 4KB Sector Hard-Disk Drives
You cannot reconfigure 4KB sector hard-disk drives with virtual disks that consist of 512B sector hard-
disk drives and vice versa.
