As part of a recent deployment I’ve been implementing EMC VSI for VMware vSphere Web Client v6.5 in a vSphere 5.5 environment. If you’re not familiar with this product, it “enables administrators to view, manage, and optimize storage for VMware ESX/ESXi servers and hosts and then map that storage to the hosts.” It covers a bunch of EMC products, and can be really useful in understanding where your VMs sit in relation to your EMC storage environment. It also really helps non-storage admins get going quickly in an EMC environment.
To get up and running, you:
- Download the appliance from EMC;
- Deploy the appliance into your environment;
- Register the plug-in with vCenter by going to https://ApplianceIP:8443/vsi_usm/admin;
- Register the Solutions Integration Service in the vCenter Web Client; and
- Start adding arrays as required.
So this is all pretty straightforward. BTW the default username is admin, and the default password is ChangeMe. You’ll be prompted to change the password the first time you log in to the appliance.
So the problem for me arose when I went to register a second SIS appliance.
By way of background, there are two vCenter 5.5 U2 instances running at two different data centres. I do, however, have them running in Linked Mode. And I think this is the problem. I know that you can only register one instance at a time with one vCenter. While it’s not an issue to deploy a second appliance at the second DC, every time I go to register the service in vCenter, regardless of where I’m logged in, it always points to the first vCenter instance. Which is a bit of a PITA, and not something I’d expected to be a problem. As a workaround, I’ve deployed one instance of the appliance at the primary DC and added both arrays to it to get the client up and running. And yes, I agree, if I have a site down I’m probably not going to be super focused on storage provisioning activities at my secondary DC. But I do enjoy whinging about things when they don’t work the way I expected them in the first instance.
I’d read in previous versions that Linked Mode wasn’t supported, but figured this was no longer an issue as it’s not mentioned in the 6.5 Product Guide. This thread on ECN seems to back up what I suspect. I’d be keen to hear if other people have run into this issue.
