Checking the power status of a PCI Express slot
See ‘Checking the power status of a PCI Express slot’ in “4.6.2 PCI Express card replacement procedure in
detail”.
Powering off PCI Express slots
See ‘Powering on and off PCI Express slots’ in “4.6.2 PCI Express card replacement procedure in detail”.
4.8.3 FC card (Fibre Channel card) removal procedure
The descriptions in this section assume that an FC card is being removed.
Notes
- The FC card used for SAN boot does not support hot plugging.
- 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 “4.6.2 PCI Express card replacement procedure
in detail”.
3. Power off the PCI Express slot.
See ‘Powering on and off PCI Express slots’ in “4.6.2 PCI Express card replacement procedure in detail”.
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).
