Why Fc device is still mounted in single user mode?
 
Hi All,

I recently rebooted my server to fix some disk error, I　entered single user mode first, and I can see that all the Fc devices are still mounted. why since network is disabled by default in single user mode?

Thanks in advance.

FC devices = fiber channel?

if so you probably have the modules needed to load your fiber channel card in your kernel or initrd so the system thinks they are local disks.

can you post your fstab?

Hi,

Does this mean Fibre channel do not need IP network support?

Thanks

I think this would explain your question:

How does the Linux kernel know which drivers to load at boot?

excerpt from link above:

The kernel generates events for devices on e.g. the PCI bus when they are plugged (either hot or cold; events are queued until userspace runs AFAIR). udev will receive these events and do modprobe calls which include the PID/VID (product/vendor IDs) of the device(s); this is usually a string with some * in it. modprobe will then calculate the intersection of the set expressed by udev's load request wildcard and the set of aliases of kernel modules (themselves being possibly wildcards).

fiber channel is separate from ethernet or IP networking.

iscsi would need the IP networking.
