Default Red hat linux server lost connectivity to the storage. Please suggest.

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
Host Adapter (rev 02)
05:00.0 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel
Host Adapter (rev 02)
05:00.1 Fibre Channel: Emulex Corporation Zephyr-X LightPulse Fibre Channel
Host Adapter (rev 02)

Please suggest or point us in the right direction.

Thanks
