Hot-Pluggability

Hot-pluggability refers to the ability to remove and replace a component

without interfering with system operation. There are three components in a

ProLiant Storage System /U system that are considered hot-pluggable:

■ Drives - Failed hot-pluggable drives in fault-tolerant configurations can

be replaced without interrupting system operation. The data on the

failed drive will be automatically restored on the replacement drive.

■ Fan array - If one of the cooling fans in the storage system should fail

(status indicator is amber), the entire fan array can be replaced without

interrupting system operation.

■ Power supply - In systems with the optional redundant power supply

installed, either power supply may be removed and replaced without

interrupting system operation.

See Chapter 4 for specific limitations when replacing hot-pluggable

components. It is important to understand that the hot-pluggability features

must also be supported by the operating system, and in the case of the drives,

the SCSI controller. See Table 1-2.
