PCI Hot Plug
PCI Hot Plug is an industry-standard solution that provides increased system availability and non-stop
serviceability in business-critical computing environments. PCI Hot Plug enables PCI networking adapters
to be replaced or added to a server without taking the system down. HP pioneered this technology and
has worked closely with the PCI Special Interest Group (SIG) and several key industry partners to
accelerate its adoption as an industry standard. PCI Hot Plug technology also has a broad range of
industry support from leading operating system suppliers including Microsoft® and Novell.
HP server adapters support PCI Hot Plug technology. To take advantage of this solution, you must use the
adapter in an HP or third-party system that supports PCI Hot Plug. To implement PCI Hot Plug, use the
configuration instructions that come with your system. If you use an HP system that supports PCI Hot Plug,
refer to the documentation for configuring and installing PCI Hot Plug devices in the HP SmartStart
application, which ships with HP systems.
If you use a third-party system that supports PCI Hot Plug, refer to the documentation that came with your
system or contact technical support for the vendor.
Support for enabling PCI Hot Plug
Different operating systems support PCI Hot Plug in different ways. The following list describes how
different operating systems enable PCI Hot Plug devices.
• Windows® 2000, Windows Server 2003, and Windows Server 2003 x64
o Can replace like item for like item
o Can add a new adapter to an empty slot
o Can add an option module to an existing NC3134 adapter
• Windows NT® 4.0
o Can replace like item for like item
o Cannot add a new adapter to an empty slot
• NetWare 6.x
o Can replace like item for like item
o Can remove an adapter
o Can add a new adapter to an empty slot
o Can add an option module to an existing NC3134 adapter (This feature is not supported on an
NC3134 adapter that has a persistent driver installed.)
• UnixWare 7.x and OpenServer 6.x
Requires hardware that implements PCI Hot Plug failover and a DDI 8 MDI driver that implements the
CFG_SUSPEND and CFG_RESUME subfunctions to the entry point routine. This lets the system
administrator suspend the driver, power down the slot, hot-swap or hot-replace the adapter, power
up the slot, and resume the driver, all without bringing the machine down. For further information
about PCI Hot Plug support, refer to your UNIX documentation.
• SCO OpenServer 5.x
