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 S140 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 S140.
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.
