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.
