Situation

This is an environment with SAN/Storage, with (Brocade) Switch and Qlogic QLE2562 HBAs in the servers. 
A SPEED of 8GB/s is configured on the HBA and on the Switch.

- Rebuild the initrd (using mkinitrd)
- Reboot the system 
- Verify that the new firmware is loaded (fw=5.03.01 or higher) by using for instance
