vSphere HA - Dealing with storage hba/link failure?

  • 772

I'm looking at putting in a small cluster spanning two locations on the same campus.

The vSphere hosts in each location would have a vSwitch connected to the production LAN, and I'd also be using a physical dedicated iSCSI LAN which would have switches in both locations with dedicated 10gbps fibre between both.

If the iSCSI fibre fails both hosts would be up and able to ping the other, but one host would not be able to see the iSCSI shared storage.

I can't find a guide that details how to configure HA in the situation above.

Thanks in advance.

    There's nothing to configure. If a host loses its storage then it can't maintain its VMs, at which point if it has VMKernel access to one or more hosts it'll announce itself as down at which point those hosts able to restart the down hosts last known VMs will do so according the the HA plan and policies. Once the downed host gets its storage back it'll rejoin the HA cluster at which point its capable of taking load, either manually or via DRS.

    Oh and don't forget that the VMKernel NICs have to be on the same VLAN, but I'm sure you've thought of that.

    Hope this helps.
