# /sbin/ifup ethX 

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. 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-scripts/temp 

20. 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. 

 

When performing hot replacement of NICs used for iSCSI connection, use the following procedures. 

- 

- 

- 

A supplementary explanation of the procedure follows. 

- 

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.
