Enable Jumbo frames on a Qlogic iSCSI HBA

Last week I was googling for a post on how to enable Jumbo frames in VMware ESXi on a Qlogic QLE406Xc iSCSI HBA. There are a couple of great post on how to enable Jumbo frames on Software iSCSI, like these:

But they didn’t provide the solution for me.

To set the MTU of the iSCSI HBA you need to be in the Bios of the card. So restart the host and at the right moment press Control + Q.

Slide1

When you’re in the Qlogic Fast!Util(bios) Choose the HBA and press enter:

Slide2

Choose Configuration Settings, and press enter:

Slide3

Choose Advanced Adapter Settings, and press enter:

Slide4

In the Advanced Adapter Settings go to te MTU setting and press enter:

Slide5

In the pop-up menu choose 9000 and press enter:

Slide7

Check if the MTU setting is correct and press Escape:

Slide8

In the pop-up screen choose to save the changes and press enter:

Slide9

Do this for all HBA’s in the host and reboot the server.

Your iSCSI HBA’s now have an MTU of 9000 (Jumbo frames). Make sure your SAN (in our case an EMC VNXe3300) also supports jumbo frames.
