CHAPTER 7 PCI Card Hot Maintenance in SUSE Linux Enterprise Server 12
7.7 Hot Replacement of PCI Express Cards
Also, if the single NIC interface has a VLAN device and the VLAN interface was temporarily removed,
restore the VLAN interface. If the priority option has changed, set it again.
# /sbin/vconfig add ethX Y
# /sbin/ifup ethX.Y
(enter command to set VLAN option as needed)
[For SLAVE under bonding]
Execute the following command to incorporate the SLAVE interface into the existing bonding
configuration. Incorporate all the necessary interfaces.
# /sbin/ifenslave bondY ethX
The VLAN-related operation is normally not required because a VLAN is created on the bonding device.
19. Mount all cables connected to the particular PCIC.
This step is performed by the field engineer in charge of your system.
Note
In GLS configuration with NIC switching way, you do not need to perform this step.
20. Remove the directory to which the interface configuration file was saved.
After all the interfaces to be replaced have been replaced, remove the save directory created in step 6 by
executing the following command.
# rmdir /etc/sysconfig/network/temp
21. Execute the higher-level application processing required after NIC replacement.
Perform the necessary post processing (such as starting an application or restoring changed settings) for
the operations performed for the higher-level applications in step 3.

7.7.5 Hot replacement procedure for iSCSI (NIC)

When performing hot replacement of NICs used for iSCSI connection, use the following procedures.
- 7.1.1 Overview of common replacement procedures for PCI Express cards
- 7.1.2 PCI Express card replacement procedure in detail
- 7.1.4 Network card replacement procedure
A supplementary explanation of the procedure follows.
Prerequisites for iSCSI (NIC) hot replacement
- The prerequisites for iSCSI (NIC) hot replacement are as follows.
- The storage connection is established on a multipath using DM-MP (Device-Mapper Multipath) or
ETERNUS multidriver (EMPD).
- To replace more than one iSCSI card, one card at a time will be replaced.
- A single NIC is configured as one interface.
Work to be performed before iSCSI (NIC) replacement
For iSCSI (NIC) hot replacement, be sure to follow the procedure below when performing Step 2 of the 'NIC
replacement procedure' in
