4.7.3 FC card (Fibre Channel card) addition procedure
The descriptions in this section assume that an FC card is being added.
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 addition procedure
The procedure for adding new FC cards and peripherals is as follows.
1. 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”.
2. Confirm that power status of the PCI Express slot
See ‘Checking the power status of a PCI Express slot’ in “4.6.2 PCI Express card replacement procedure
in detail”.
3. Physically add the target card by using MMB Maintenance Wizard.
For details on the operation of replacement, see step 1 to 7 of ‘Operation for Hot replacement of PCI
Express card by Maintenance Wizard’ in “4.7.2 PCI Express card addition procedure in detail”.
4. Reconfigure the peripheral according to its manual.
For example, suppose that the storage device used is ETERNUS and that the host affinity function is
used (to set the access right for each server). Their settings would need to be changed as a result of FC
card replacement.
5. Connect the FC card cable.
6. Power on the PCI Express slot.
See ‘Powering on and off PCI Express slots’ in “4.6.2 PCI Express card replacement procedure in detail”.
