Procedure:
1. Copy STORCON.EXE and the IIR firmware file on to bootable DOS diskette.
2. Place diskette in drive A: and boot your system.
3. Once booted, type "storcon /defect" at the A:\ prompt.
4. When Storage Console loads, perform the firmware update procedure, starting at step 3, as
described in the appendix section titled FLASH Memory Programming.
PCI Hot Plug Overview
The PCI Hot Plug (PCI HP) specification defines the requirements for adapter cards, system
platforms, and system software to enable the insertion and removal of PCI adapter cards without
turning off the platform or rebooting the operating system. The process may include stopping a
portion of the software or controlling the power cycle of a portion of the hardware such as, in this
case, a PCI slot. This industry standard offers customers higher system availability by helping to
eliminate both planned and unplanned downtimes.
PCI HP requires network operating system (NOS) and PCI adapter driver support. PCI HP is
different from other types of hot swapable devices since such devices (like a fan or power supply)
do not require the cooperation or knowledge of the NOS or any specialized driver in order to
perform an online replacement.
A PCI Hot Plug system requires a hot plug platform, a hot plug OS, and hot plug adapter drivers. A
system can include any combination of hot plug and conventional versions of each of these
components, including a mix of both hot plug and conventional adapter drivers. However, a
particular adapter can be hot plugged only if all three components for that adapter support hot plug
operation.
PCI Hot Plug enables the features of replacement/repair (Hot Replacement), addition (Hot
Addition), adapter update, and deletion (Hot Deletion) of PCI adapters. Hot Replacement consists
of replacing a malfunctioning adapter in a system utilizing, in sequence, the Hot Removal followed
by the Hot Insertion functions of PCI Hot Plug. Hot Addition consists of adding a completely new
device to the system utilizing the Hot Insertion function of PCI Hot Plug. Hot Deletion consists of
removing (but not replacing) an existing adapter in a system utilizing the Hot Removal function of
PCI Hot Plug.
There are two basic functions of PCI Hot Plug:
Hot Insertion
The insertion of a device into a powered-down PCI HP slot only (the system remains powered on)
and power up of that slot once device is inserted. This assumes that driver for (PnP) device being
inserted does not require reboot or driver is already loaded.
Hot Removal
Removal of a device by first powering down the HP PCI slot on which the device is inserted then
physically removing the device from the HP PCI slot. Surprise Removal, the removal of the card
while the slot still powered, is not supported.
