System Hangs When Performing a Hot Plug Operation
After you load the hot plug driver on your system, you will see slots listed in the
/sys/bus/
pci/slots
directory.
2. Review the available Emulex PCI device IDs by issuing the
lspci
command.
This command lists the devices that are available for hot plugging.
#
lspci |grep -i Emulex
08:00.0 Fibre Channel: Emulex Corporation Lancer-X: LightPulse Fibre Channel Host
Adapter (rev 10)
08:00.1 Fibre Channel: Emulex Corporation Lancer-X: LightPulse Fibre Channel Host
Adapter (rev 10)
3. Use the
cd
command to navigate to the directory where slots are listed, and issue the
ls
command to review the available PCI devices.
#
cd /sys/bus/pci/slots
#
ls
4. From the slots that are displayed, map the listed slots to the device IDs that were listed in
Step 2.
5. Verify the power status of the slots by issuing the
cat
slot-device-ID/power
command for
each available slot.
#
cat 0000\:08\:00.0/power
# 1
#
cat 0000\:08\:00.1/power
# 1
In this example, the output of
1
indicates the slots are powered up.
6. Issue the
echo 0 >
slot-device-ID
/power
command to power down the slot that you
want to use for hot plugging.
7. Verify that you have powered down the slot by issuing the
ls
command.
#
ls
0000:08:00.1
In this example, you can see the first slot is powered down, because only the second slot is
listed.
8. Perform the hot plug operation by inserting the card into the slot that you powered down.
9. Issue the
cd
command to navigate to the directory of the powered down slot, and then issue
the
echo 1 >
slot-device-ID
/power
command to power up the slot.
