PCI Hot Plug Utilities
You can use either the PCI Hot Plug button on the server or your operating
system PCI Hot Plug utility to control the PCI Hot Plug slots.
■ The PCI Hot Plug button allows for PCI Hot Plug access directly at each
PCI slot, which provides PCI Hot Plug control directly at the server
without requiring the PCI Hot Plug utility software.
■ You can also use the utility software to replace a card in the hot-plug
slot or configure a board that you have already added to the system. The
PCI Hot Plug utility software allows you to enable or disable specific
slots to the system. Compaq, in partnership with Microsoft, Novell and
SCO, has developed PCI Hot Plug software support for each operating
system. For more information on the PCI Hot Plug software application,
refer to “PCI Hot Plug Important Facts” in the online PCI Hot Plug
Administration Guide or in materials on the Documentation CD.
Additional information is available in Chapter 7, “Server Configuration
and Utilities.”
IMPORTANT: OS/2 and Solaris operating systems do not support PCI Hot Plug
technologies.
Hot-Plug SCSI Hard Drives
IMPORTANT: Before adding or removing any hot-plug SCSI drives, place the server in
Standby mode. Refer to your operating system instructions for additional instructions.
Important Guidelines For Replacing
Hot-Plug SCSI Hard Drives
When replacing hot-plug hard drives, observe the following guidelines:
■ Never remove a hot-plug drive if the drive’s LED is green. Replace a
hot-plug hard drive only when its LED is amber-colored.
■ Never remove more than one drive at a time. When a drive is replaced,
the controller uses data from the other drives in the array to reconstruct
data on the replacement drive. If more than one drive is removed at a
time, the complete data set needed to reconstruct data on replacement
drives will not be available.
■ Never remove a working drive when another drive has failed. An amber
LED light indicates a drives in failure mode. Permanent data loss occurs
if a working drive is removed when replacing a failed drive.
