Pci Hot-Plug User Interfaces; How To Initiate A Reconfiguration Boot - Sun Microsystems Fire V890 Service Manual

PCI Hot-Plug User Interfaces

There are two different methods for performing PCI hot-plug operations on Sun Fire
V890 systems:
Push-button method
■
Command-line method
■
The push-button method relies on push buttons and status LEDs located near each
PCI slot. You can initiate a hot-plug operation by pressing the push button for the
corresponding slot. The command-line method lets you perform hot-plug operations
via a remote login session, a Remote System Control (RSC) console, or a locally
attached console. This method involves the Solaris cfgadm(1) command.
Both hot-plug methods make use of the status LEDs located near each PCI slot.
These LEDs indicate where and when it is safe to insert or remove a card, and also
show whether the operation has succeeded or failed. For additional details on hot-
plug status LEDs, see
Note – Regardless of the method you use, it is often necessary to perform additional
administrative steps to prepare for a hot-plug removal operation. Prior to
performing a removal operation, you must ensure that the devices residing on the
board are not currently in use. To identify and manually terminate usage of such
devices, you can use standard Solaris Operating System commands such as
mount(1M), umount(1M), swap(1M), ifconfig(1M), and ps(1).
For detailed PCI hot-plug procedures, refer to the Sun Fire V890 Dynamic
Reconfiguration User's Guide, which is available at http://docs.sun.com, under
Solaris on Sun Hardware. Refer to the Sun Fire V890 Server Product Notes for late-
breaking details.

How to Initiate a Reconfiguration Boot

After installing any new internal option or external storage device, you must
perform a reconfiguration boot so that the operating system is able to recognize any
newly installed devices. In addition, if you remove any device and do not install a
replacement device prior to rebooting the system, you must perform a
reconfiguration boot in order for the operating system to recognize the configuration
change. This requirement also applies to any component that is connected to the
system's I
supplies.
