Hi,

One of our redhat server that was earlier zoned to EMC storage is not able
to see any LUNs/Disks all of a sudden.

We are not seeing any entries in /sys/class/fc_host.

# ls -ld /sys/class/fc_host
ls: /sys/class/fc_host: No such file or directory


# more /etc/redhat-release
Red Hat Enterprise Linux Server release 5.2 (Tikanga)

# uname -r
2.6.18-128.4.1.el5

# lspci | grep -i fibre
04:00.0 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel
Host Adapter (rev 02)
04:00.1 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel

Please suggest or point us in the right direction.

Thanks
