Be careful updating microcode. Its best to determine what the latest levels are for your hardware, then verify compatibility between connecting hardware.

For example, before upgrading the microcode on your HBA, you might want to make sure what level of firmware is required on your DS4300 or you McData SAN switch to maintain compatability.

You should never assume you can update one component and all others will continue to work properly.

Microde updates require research and planning. Take the time to do the extra work to ensure success.
