PCI Hot-Plug User Interfaces
There are two different methods for performing PCI hot-plug operations on
Sun Fire 880 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 PCI hot-plug operation by pressing the push button for
the corresponding slot. The command-line method lets you initiate PCI hot-plug
operations via a remote login session, an 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 board, and also
show whether the operation has succeeded or failed. For additional details on
hot-plug status LEDs, see “About PCI Slot LEDs” on page 161.
Note –
Regardless of the method you use, it is often necessary to perform additional
administrative steps to prepare for a PCI hot-plug removal operation. Prior to
performing a removal operation, you must ensure that the devices residing on the
card are not currently in use. To identify and manually terminate usage of such
devices, you can use standard Solaris operating environment 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 880 Dynamic
Reconfiguration User’s Guide , available on the Solaris on Sun Hardware AnswerBook .
