Why the DELL storage volumes not appearing in Vmware host?

This is using a DELL Poweredge R630 physical server, setup as VMware ESXi 6.0 U2 host. A DELL Compellent SCv2020 2U storage also purchased. This storage came with 2 controllers, with 4-port SAS interfaces. A 12 Gbps SAS HBA card (dual-port) is connected to the host. From the host HBA card, I connected 2 SAS cables to the "port 1" of both top and bottom SAS interfaces of the SCv2020.

After that, VMware ESXi 6.0 U2 was setup successfully on server's SDCards. I used DELL Storage Enterprise manager client to initialise and setup the SCv2020 storage. Server was defined, since only a server, no server cluster is created. A test volume of 500 Gb is created and "mapped" to the host. Everything seems fine.

However, in vSphere client connected to the host, in Configuration > Storage adapter, no doubt the 12 Gbps SAS HBA card is detected, no storage and volume were "allocated" after the scan. I don't think I did the setup wrong. Could it be the SAS HBA driver has to be explicitly download and install again?

Thanks in advance.

Hi,

if I check the vmware compatibility guides here :
http://www.vmware.com/resources/compatibility/search.php?deviceCategory=san

I see Storage Center model, so I suppose it concerns SC series and your San model.
You'll see you need your San firmware version to be at least 6.6 (or 6.7 or 7.0 or 7.1), otherwise your configuration is not supported.

Also note that your Multipathing policy in ESXi must be Round Robin as stated too in the compatibility guides.

As per your SAS hba driver in ESXi, did you install the Dell custom iso of ESXi ?


Are these 3 settings (firmware version, multipath policy, good ESXi iso source) correct in your configuration ?

Hi all,

I found this DELL article > http://www.dell.com/support/article/us/en/19/how11081;
After downloading and updating with the suggested driver, the volumes were mapped successfully.

Ok, so it was a driver version issue.
You did not tell me if you use the Dell custom ESXi iso to install ESXi.. it could matter.

Hi mrtortur,

It doesn't matter. I tried both, either DELL custom ESXi iso or VMware original ESXi iso works.

By using the suggested article, it works. Now, the volume mapping is working perfectly.
