Dell VRTX + vCenter 5.5 + Shared storage == ESXi host import issue into vCenter. Please help!

All,

I have two VRTX to be used for lab purposes that I am currently configuring.

The VRTX feature 4 blades with a shared storage infrastructure. Each blade has ESXi 5.5 installed on it.

I have configured the shared storage on the VRTX and all of the blades can access it just fine.

The issue I am currently facing is when adding the ESXi hosts to vCenter for management.

Adding the first host goes without a hitch. However, adding any subsequent host fails because vCenter finds datastore attached to the hosts to have the same ID.

The error message is (see the attached screenshot): "Datastore 'Primary-Shared-Storage' conflicts with an existing datastore in the datacenter that has the same URL (ds://vmfs/volumes/xxxxx/), but is backed by different physical storage".

Anyone knows how to resolve this?

Thanks.

Thanks for the reply.

I think I have found a workaround.

First, that link does not address my particular issue.

See, this is a brand new vCenter appliance install and configuration. Only one host of the four hosts to be added was added.

The issue again is that each ESXi host is a VRTX blade (M620), which has access to the datastore created on the shared VRTX storage.

Basically, each host is mounting the same shared datastore (the single datastore created on the shared storage), which works fine except for vCenter complaining when importing the hosts.

In any case, my resolution was as follow:

- Add the first host with the datastore attached and mounted

- Unmount the datastore and detach the shared controller from the other hosts before adding them in vCenter

- Re-attach the shared controller and mount the datastore through vCenter after the hosts were added

- Re-configure each host for vSphere HA if needed

Thanks.

These steps also worked for me with the VRTX

I have encountered the same problem, after upgrading the PERC8 driver to 06.802.71.00, issue can fix.

Download driver from https://my.vmware.com/web/vmware/details?downloadGroup=DT-ESXI5X-DELL-MEGARAID_SAS-068027100&product...
