Equallogic Round Robin MPIO

Currently we are running VMFS volumes on HP Lefthand storage, i've linked 4 iSCSI VMKernels to one vmhba and changed the default load balancing option to Round Robin with every 3 IOPS.

Now I want to add Dell Equallogic storage and reuse the same configuration. I've added a rule in rc.local that every with a  identifier naa.6090 wil use Round Robin every 3 IOPS.

The Equallogic volumes are now set to Round Robin, but only use one adapter from the vmhba. On the Equallogic i've set Allow simultaneous connections on the volumes, but it still wont work.

I can use the Equallogic Multipathing Extension Module, but it wil only create a new vSwitch, i want to use the configured vmhba just like the HP Lefthand storage.

Output HP Lefthand LUN:

naa.6000xxxxxxxxxxxxxxxxxxxxx
    Device Display Name: LEFTHAND iSCSI Disk (naa.6000xxxxxxxxxxxxxxxxxxx)
    Storage Array Type: VMW_SATP_DEFAULT_AA
    Storage Array Type Device Config: SATP VMW_SATP_DEFAULT_AA does not support device configuration.

Output Dell Equallogic LUN:

Hi

I have setup Equalogic Round Robin MPIO many times without any issues using this document.

Thanks for the documentation, but on Equallogic.com there's a newer version compatible with ESX 4.1.

Yesterday I've reboot all the ESXi hosts, and now all the iSCSI adapters are active.

Verry strange :smileyconfused:
