perform below operations:
- Pull up the IOU from the cabinet physically.
- Integrate the IOU into other inactive partition.
- Hot add the IOU into other active partition.
Perform the necessary post processing (such as re-starting an application) for the operations performed for

4.6 Hot Replacement of PCI Express Cards
This section describes the following methods of PCI Express card replacement with the PCI Hot Plug (PHP)
function:
- Common replacement operations for all PCI Express cards such as power supply operations
- Specific operations added to procedures to use a specified card function or a driver for installation
There are two ways to perform PCI hot plug:
- Operation by using sysfs
- Operation by using dr commands
You can perform the operation by using dr 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 dr commands to prevent wrong operation.
Hereafter, description about the operation by using dr 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'.
Notes
- If you replace PCI Express cards on an IOU, see
- In hot replacement of PCI Express cards, if you reboot the partition on OS without hot adding new PCI
card to same PCI Express slot after you performed hot remove command, you cannot hot add a PCI
Express card to the PCI Express slot unless you power off the partition.
If you reboot the partition on OS before hot adding, you must power off the partition and replace the PCI
Express card.
- If the Extended Partitioning is enabled, dr command is not supported for PCI Express card hot
replacement.
