Home / Disabling FC Fibre Channel Card in Linux
The "lspci" command can be used to display the available Fibre Channel (FC) Adapters: The Fibre Channel (FC) HBA port access on RedHat can be temporarily disabled using the unbind string against the pci-device-id bus address. Red Hat Enterprise Linux 8 provides the following native Fibre Channel drivers: 10. Re-scanning Fibre Channel logical units after resizing a LUN If you changed the logical unit number (LUN) size on the external storage, use the echo command to update the kernel's view of the size. The following article describes how you can temporarily (unbind) disable HBA (Fibre Channel) ports (controllers) on RedHat for testing Veritas Dynamic Multi-pathing (DMP) behaviour and vxattachd interoperability.
