Is it possible to multipath across multiple iSCSI HBAs

I have Dependent iSCSI HBAs (Broadcom quad port NICs with iSCSI Offload). Each NIC presents itself as an individual HBA to the Host.

If I configure 2 of said NICs as iSCSI HBAs, and present the disks to them instead of using the software initiator, will it perform multipathing or get confused and present the drive twice?

It should perform multipathing.

When you start your ESX/ESXi host or rescan your storage adapter, the host discovers all physical paths to storage devices available to the host. Based on a set of claim rules defined in the /etc/vmware/esx.conf file,the host determines which multipathing plug-in (MPP) should claim the paths to a particular device and become responsible for managing the multipathing support for the device.

Never mind, the Broadcom HBAs are not supported as proper Hardware iSCSI adapters in VMware anyway.

Will  be sticking with the Software intiator.

Thanks Hank!

I agree though, as a general question, MPPs are SAN vendor/model specific not HBA specific so in theory it should work.

There are so many 'should's' in VMware circles don't you find!
