esxcfg-hwiscsi ARP redirect enable fails on IBM/Em...

felgercarb · ‎01-21-2014

We recently installed a couple of IBM PureFlex chassis with x240 compute nodes. We're using the IBM-custom image of ESXi 5.1 (build 799733), unpatched at the moment as this is a brand-new configuration. To interoperate properly with our Compellent SAN, with which we're using pure iSCSI, I need to enable ARP redirect on the nodes' Emulex HBAs. The nodes have Emulex CN4054 mezzanine cards with the iSCSI offload feature-on-demand enabled. When I try to enable ARP redirect on these adapters, the command fails.

~ # esxcfg-hwiscsi -l vmhba1

DHCP Configuration Disabled

ARP Redirection Disabled

MTU Size = 8342

~ # esxcfg-hwiscsi -a allow vmhba1

Allowing ARP redirection failed.

Can someone please offer an opinion on why this command fails? I also tested enabling/disabling jumbo frames, which failed similarly.

Thanks in advance!

then Run 2nd command to enable ARP Redirect: esxcfg-hwiscsi -a allow vmhba#

Take care!

Perhaps it wasn't clear that these lines from the middle of my original post were the output from the commands you recommended:
