3. Power off the PCI Express slot.
See 'Powering on and off PCI Express slots' in
4. After taking off all cables connected to the target card, physically remove the target card.

4.8.4 Network card removal procedure

Network card (referred to below as NIC) removal using hot plugging needs specific processing before and
after PCI slot power-on or power-off. Its procedure also includes the common PCI Express card removal
procedure.
The procedure describes operations where a single NIC is configured as one interface. It also describes
cases where multiple NICs are bonded together to configure one interface (bonding configuration). For
bonding multiple NIC by using PRIMECLUSTER Global Link Services (GLS), see 'PRIMECLUSTER Global
Link Service Configuration and Administration Guide Redundant Line Control Function' (J2UZ-7781).
NIC removal procedure
This section describes the procedure for hot plugging only a network card.
Note
When removing multiple NICs, be sure to remove them one by one. If you do this with multiple cards at the
same time, the correct settings may not be made.
1. Confirm the slot number of the PCI slot that has the mounted interface.
Confirm the interface mounting location through the configuration file information and the operating
system information.
First, confirm the bus address of the PCI slot that has the mounted interface to be removed.
# ls -l /sys/class/net/eth0/device
lrwxrwxrwx 1 root root 0 Sep 29 09:26 /sys/class/net ¥
/eth0/device
->../../../0000:00:01.2/0000:08:00.2/0000:0b:01.0
The ¥ at the end of a line indicates that there is no line feed.
Excluding the rest of the directory path, check the part corresponding to the file name in the symbolic link
destination file of the output results. In the above example, the underlined part shows the bus address.
("0000:0b:01" in the example)
Next, check the PCI slot number for this bus address.
# grep -il 0000:0b:01 /sys/bus/pci/slots/*/address
/sys/bus/pci/slots/20/address
Read the output file path as shown below, and confirm the PCI slot number.
/sys/bus/pci/slots/<slot number>/address
Notes
If the above file path is not output, it indicates that the NIC is not mounted in a PCI slot (e.g., GbE port in
the IOU).
With the PCI slot number confirmed here, see
and Slot Numbers
