1-7 Introduction to the ProLiant Storage System /U
Compaq ProLiant Storage System /U User Guide
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.
