Although you can hot replace FC card used for dump device of sadump, collecting dump of memory fails
until reconfiguring HBA UEFI or extended BIOS with the partition inactive after replacing the FC card.

This section does not cover configuration changes in peripherals (e.g., UNIT addition or removal for a
SAN disk device).

This manual does not describe how to change the configuration of peripherals such as expanding and
removing the unit of SAN disk device.

To prevent a device name mismatch due to the failure, addition, removal, or replacement of an FC card,
access the SAN disk unit by using the by-id name (/dev/disk/by-id/...) for the device name.

If all the paths in a mounted disk become hidden when an FC card is hot replaced, unmount the disk.
Then, execute PCI hot plug.

FC card removal procedure

The procedure for removing an FC card and peripherals is as follows.

1. Make the necessary preparations.

Stop access to the FC card by stopping applications or by other such means.

2. Confirm the slot number of the PCI slot by using the following procedure.

See ‘Confirming the slot number of a PCI Express slot’ in “

3. Power off the PCI Express slot.

4. 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).
