For a newly added bonding interface with a SLAVE interface, execute the following command to activate
the interfaces. You need not execute the ifenslave command individually for the SLAVE interface.

Removing PCI Express cards
This section describes the PCI Express card removal procedure with the PCI Hot Plug function.
The procedure includes common steps for all PCI Express cards and the additional steps required for a
specific card function or driver.
Thus, the descriptions cover both the common operations required for all cards (e.g., power supply
operations) and the specific procedures required for certain types of card. For details on removal of the cards
not described in this section, see the respective product manuals.

There are two ways to perform PCI hot plug:
-
Operation by using sysfs
-
Operation by using dp commands
You can perform the operation by using dp commands if Dynamic Reconfiguration utility is installed in the
partition. If not, be sure to use the operation by using sysfs. Although you can perform the operation by using
sysfs even if Dynamic Reconfiguration utility is installed in the partition, it is recommended to perform the
operation by using dp commands to prevent wrong operation.
Hereafter, description about the operation by using dp commands starts at ‘For the partition with Dynamic
Reconfiguration utility installed’ and description about the operation by sysfs starts at ‘For the partition without
Dynamic Reconfiguration utility installed’.
Note
If you hot add PCI Express cards into an IOU, see ‘

4.8.1 Common removal procedures for all PCI Express cards
1. Performing the required operating system and software operations depending on the PCI Express card
type
2. Powering off a PCI slot
3. Removing a PCI Express card
4. Performing the required operating system and software operations depending on the PCI Express card
type
Note
This section describes instructions for the operating system and subsystems (e.g., commands, configuration
file editing). Be sure to refer to the respective product manuals to confirm the command syntax and impact on
the system before performing tasks with those instructions.
The following sections describe card removal with the required instructions (e.g., commands, configuration
file editing) for the operating system and subsystems, together with the actual hardware operations. Step 3 is
performed by the field engineer in charge of your system.
