Physical Disks
NOTE: The physical disks in a virtual disk must be of the same drive type (HDD, SSD or NVMe PCIe SSD). For example, you
cannot mix an HDD and an NVMe PCIe SSD in the same virtual disk.
NOTE: The drive activity LED blinks continuously while there are background tasks running on the disk.

Physical disk features
Physical disk roaming
Physical disk roaming is moving the physical disks from one cable connection or backplane slot to another on the same
controller. The controller automatically recognizes the relocated physical disks and logically places them in the virtual disks,
which are part of the disk group. You can perform disk roaming only when the system is turned off.
CAUTION:
Do not attempt disk roaming during online capacity expansion (OCE). This causes loss of the virtual
disk.
Physical disk hot-swapping
NOTE: To check if the backplane supports hot swapping, see your system documentation.
Hot-swapping is the manual replacement of a disk while the PERC S150 is online and performing its normal functions. The
following requirements must be met before hot-swapping a physical disk:
● The system backplane or enclosure must support hot swapping for the PERC S150.
● The replacement disk must be of the same protocol and disk technology. For example, only a SATA hard drive can replace a
SATA hard drive and only a SATA SSD can replace a SATA SSD.
NOTE: Disk hot-swapping is not supported in UEFI HII; it is supported only in OS mode.
NOTE: When hot-swapping a physical disk, ensure that the new disk is of equal or greater capacity to the physical disk that
is being replaced.
Physical disk power management
Power management is a power-saving feature of the PERC S150. This feature supports power management of SATA hard drives
(HDD) by using Extended Power Conditions (EPC). The EPC feature set provides the host with additional methods to control
the power condition of a device.
Physical disk failure detection
Physical disk failure is detected and the controller automatically rebuilds a new physical disk assigned as a hot spare.
NOTE: Refer to drive mixing restrictions for rebuilding.
