Enable Jumbo Frames on Hardware ISCSI HBA vmhba

posted 12 Jun 2011, 07:04 by Tristan Self
If you need to use jumbo frames on your ISCSI you need to run this command from the command line of the ESX host:

esxcfg-hwiscsi -j enable <vmhbaX>


esxcfg-hwiscsi -j enable vmhba1

You'll need to reboot to let the changes take effect. To verify run:
esxcfg-hwiscsi -l – lists the current settings.
